Category: Visa & Paperwork

Last updated: November 2026_

Your D-2 visa got you into Korea, but the date that matters once you’re here is the one on your Residence Card: the end of your period of stay. Degree programmes usually outlast it, so many international degree students need to extend it at least once. Korean immigration calls this an extension of stay (체류기간 연장허가); most students just call it a visa extension.

It’s usually routine. A few things can delay or complicate it: applying late, leaving Korea while the application is under review, low grades without an explanation, and unpaid health insurance premiums.

This guide is based on official guidance from Korea’s government portal and HiKorea, and on recent notices from Korean universities’ international offices. It covers when to apply, the three ways to do it, the documents, what grades and finances have to do with it, and what happens after you apply.

The short answer

• You can apply from four months before your stay expires. The deadline is the expiry date itself — or, online, one working day before it.
• There are three routes: through your university’s international office, online through HiKorea, or in person at your immigration office.
• The government fee is ₩60,000 in person, ₩50,000 online. If your university uses an agency for group applications, the total you pay can be higher — check your university’s notice.
• Core documents: application form, passport, Residence Card, proof of residence, plus a certificate of enrolment and transcript. Proof of funds is often required, though some universities’ students are exempt if they meet a grade threshold.
• Don’t leave Korea while your application is under review. Check with your international office before any trip.
• Settle any unpaid NHIS premiums first. Arrears may affect your application.

What an extension is — and isn’t

An extension keeps your D-2 status and moves the end date of your stay. It isn’t a new visa, and you can’t do it from abroad: it’s handled only inside Korea, by the immigration office with jurisdiction over your address. If you’re changing to a different status — for example D-2 to D-10 after graduation — that’s a different procedure.

When to apply

You can apply from four months before your period of stay expires, and you must apply by the expiry date. Online, the deadline is effectively one working day before expiry: HiKorea accepts online applications only on weekdays, from 07:00 to 22:00, not on weekends or public holidays. If your stay expires on a Monday, don’t count on applying online on Sunday.

A visit reservation is not an application. If you’re applying in person, booking a slot on HiKorea doesn’t count as applying — your application is received only when you visit and submit it. If your expiry date is close, make sure the visit itself happens in time.

Many universities collect extension applications in a set window each semester, often right after tuition is paid, and submit them together. That window is the deadline for using your university’s service, not your legal deadline. If you miss it, you can usually still apply yourself online or in person — but you’ll be doing it on your own, so don’t plan around missing it.

Applying late has consequences. Staying past your expiry date without a pending application is a violation of immigration law and can lead to fines, and a record of it can complicate later applications.

Three ways to apply

Route	What you pay	Notes
Through your university	Check your university’s notice — agency fees may be added	The international office files on your behalf, sometimes through an agency. At Ewha, for example, the 2026 fall group application cost ₩75,000 in total and took about four to five weeks.
Online via HiKorea	₩50,000	Upload scanned documents; no visit needed for many applicants.
In person	₩60,000	Book a visit through HiKorea in advance, then visit to submit.

Not every applicant can use the online route; some cases have to be handled in person.

Documents

Required for everyone:

• Application form (통합신청서, Form No. 34) — downloadable from HiKorea
• Passport
• Residence Card
• Proof of residence — a lease, dormitory confirmation, or similar
• Fee

Commonly required for D-2:

• Certificate of enrolment (재학증명서)
• Transcript (성적증명서)
• Proof of funds — typically a bank balance certificate in your own name from a Korean bank, or a scholarship certificate
• Proof of tuition payment for the coming semester, at some universities

Start with your international office’s checklist: it reflects what your university and its immigration office usually expect. But the final requirements are set by immigration. Documents can differ depending on your circumstances and on your university’s certification status for international students, and immigration can ask any applicant for more.

Get documents issued close to your application date. Balance certificates in particular often have to be recent.

Grades and proof of funds

Your transcript is how immigration checks you’re actually studying, and at some universities it also decides whether you need to prove your funds.

At Ewha, for example, regular-semester students whose previous-semester and cumulative GPA are both 2.0/4.3 or above are exempt from submitting proof of funds. Students in extra semesters and graduate students who have completed coursework (수료생) are not covered by the exemption (Ewha OISA).

Grades can also change what else you’re asked for:

• Students with low grades may be asked to submit a statement explaining their academic performance (학습부진사유서), and may be given a shorter extension.
• Students in extra semesters beyond the normal length of their programme are usually asked for a statement explaining why.

If your grades dropped for a reason — illness, a family emergency — explain it in writing and attach supporting documents.

Attendance matters too. Immigration expects D-2 students to attend their classes, and universities report students who stop attending. Some international offices check attendance before supporting an extension; ask yours whether it does.

Health insurance: clear it before you apply

Immigration checks National Health Insurance payment records when you apply to extend your stay, and unpaid premiums may affect your application. Check what you owe on NHIS’s website or app, pay it, and keep the receipt. NHIS Health Insurance for International Students explains how premiums and arrears work.

After you apply

• Check your application’s status. On HiKorea, you can follow it under My Page → e-application status.
• Respond to requests for more documents. Immigration may ask for supplementary documents by text or email, with a deadline. Missing it can delay or sink your application (Chosun University, 2026).
• Processing time: the government portal gives about 10 days for standard cases and up to two months if further review is needed. University group applications can take longer — four to five weeks in Ewha’s 2026 notice.
• Don’t leave Korea while it’s pending. Universities warn that leaving during review can cause problems with the application. If you must travel, ask your international office before you book.
• Once it’s approved, check the result on HiKorea and confirm the new end date. Ask your international office or immigration office how the new date will be recorded on your Residence Card — this can differ by route.
• If your address changed, report it within 15 days of moving (Getting Your ARC in Korea covers this).

Special cases

• Graduate students who have completed coursework (수료생): extending as a research student is usually possible, but universities often require registration as a research student and a supervisor’s confirmation. Ask your department and international office early.
• Finishing your degree: after graduation, D-2 extensions generally stop. You either leave Korea, change to another status such as the D-10 job-seeking visa, or apply for an extension for the purpose of departure (출국을 위한 기간연장). That’s a separate procedure for a stay of no more than 30 days, requires a flight ticket and has no fee — it isn’t a way to stay longer.
• Part-time work: an extension doesn’t renew your work permission automatically. Check the end date on your part-time work permit.

FAQ

My stay expires next week and I haven’t applied. Is it too late? Not yet. Apply online by one working day before expiry, or in person by the expiry date — remembering that a reservation isn’t an application. Tell your international office.

I missed my university’s group application window. What now? You can usually still apply yourself, online through HiKorea or in person, as long as you’re within your legal deadline (Kwangwoon University notice).

Can I apply before my tuition is paid? Some universities require proof of tuition payment, so their application window opens after the payment period. Follow your university’s schedule.

Will I get a full year? Extensions are often granted for a year or until the end of your programme, but immigration decides the length. Low grades, a short remaining study period and other factors can mean a shorter extension.

I’m an exchange student. Does this apply to me? Usually your stay is set to cover your exchange period. If your exchange is extended, talk to your international office about whether you need to apply.

Do I have to go to the immigration office? Often not — the university or online routes may cover you. But immigration can ask any applicant to visit or submit more documents.

Last updated: November 2026

Most international students meet Korea’s National Health Insurance not at a hospital but in their mailbox: a bill arrives, addressed to the place written on their Residence Card, for health insurance they don’t remember signing up for. They didn’t sign up. For students on D-2 and D-4 status, enrolment is automatic, and the premium is a recurring monthly expense to budget for, like rent.

Once you’re enrolled, you’re covered on the same terms as Korean citizens, at almost any clinic, hospital or pharmacy in the country. The rules around it — when it starts, what happens if a payment slips, whether your own insurance can replace it — are where students get caught out.

This guide is based on official guidance from the National Health Insurance Service (NHIS), the government’s legal information portal, and 2026 notices from Korean universities’ international offices. It covers students enrolled as regional subscribers on D-2 or D-4 status: who is enrolled and when, what you pay, what you get, how to pay, and what happens if a payment is missed.

The short answer

• Students on D-2 status are enrolled automatically from their date of foreign registration on first entry. Language students (D-4-1) are enrolled after six months in Korea.
• In 2026, students who qualify for the 50% student reduction pay ₩79,320 a month. That figure already includes the reduction.
• You’re covered like a Korean citizen: show your Residence Card and the insurance share is applied at the counter. You still pay a co-payment, and some treatments aren’t covered.
• Premiums are paid in advance, by the 25th of the month before.
• Unpaid premiums have consequences: late fees, restricted coverage, and possible problems when you apply to extend your stay.
• Private insurance from home doesn’t automatically replace NHIS. Exclusion is possible only in narrow cases, and NHIS decides.

Why you’re enrolled without signing anything

Korea runs a single national health insurance system, and since 2021 international students have been brought into it by default rather than by choice. You don’t fill in an application. When immigration registers you, your details pass to NHIS, and NHIS enrols you as a regional subscriber — the category for people who aren’t insured through an employer.

That’s why the first sign is usually the bill. It goes to the address on your Residence Card (ARC), which is one more reason to keep that address up to date: you must report a move within 15 days, and a bill sent to your old dormitory is still a bill you owe.

When your coverage starts

This is the part that differs most between students, so check which line is yours:

Status	Coverage generally starts
D-2 students (first entry)	the date of foreign registration
D-4-3 elementary, middle and high school students	the date of foreign registration (first entry)
D-4-1 general language trainees	after six months in Korea

D-2 covers exchange students as well as degree students, so if you’re here on exchange, the first line applies to you too. Re-entry after time abroad can be treated differently from first entry, and other statuses have their own rules — if yours isn’t in the table, ask NHIS.

Two practical consequences:

• There’s a gap before NHIS starts. For D-2 students it runs from arrival until foreign registration; for D-4-1 students it’s the whole first six months. Whatever insurance you arranged before flying is what protects you during that time. Some universities require proof of additional insurance, and many run their own group insurance — ask your international office what yours requires and offers. (Your First 30 Days in Korea has the arrival checklist.)
• “Automatic” doesn’t mean “instant paperwork.” Your registration, your NHIS record and your first bill can take a little time to line up. If you need medical care in the first weeks and aren’t sure whether you’re covered yet, NHIS can tell you your enrolment date.

What you pay

In 2026, D-2 and D-4 students who qualify for the student reduction pay ₩79,320 a month — ₩951,840 over twelve months. Universities’ 2026 notices give the same figure; it rose from ₩76,390 in 2025 and is updated once a year, so check for the new figure early in 2027.

That amount is 50% of the minimum premium that foreign regional subscribers pay. The reduction is not automatic for everyone. To qualify, both of these must apply:

• annual income amount (소득금액) of ₩3.6 million or less — some 2026 university notices express this as monthly income of ₩300,000 or less
• property tax base (재산 과세표준) of ₩135 million or less

“Income amount” here is how NHIS assesses income, and it isn’t necessarily the same as what lands in your bank account from a part-time job. If you have income in Korea — from part-time work or anything else — ask NHIS how it’s counted for you rather than estimating it yourself. Students who don’t meet the conditions pay more than ₩79,320.

The ₩79,320 is already the reduced amount; there’s no second 50% to subtract. Budget for it alongside your other fixed costs.

What it covers

NHIS covers enrolled international students on the same terms as Korean citizens. In practice:

• Show your Residence Card at reception. There’s no claim form. The insurance share is deducted on the spot and you pay the rest.
• You still pay a co-payment. Your share is smaller at a neighbourhood clinic (의원) than at a large general or university hospital, which is one reason Koreans start at a local clinic for everyday problems.
• Some treatments are non-covered (비급여) and you pay them in full. Clinics can tell you in advance whether something is covered.
• Prescriptions are filled at a pharmacy (약국) with the same insurance applied.

NHIS doesn’t cover everything, and that’s the gap university group insurance or private insurance often fills. If your university enrols you in group insurance, check whether the policy requires your NHIS premiums to be paid up. At some universities, Sogang among them, group insurance covers you only if your NHIS premiums aren’t overdue.

How to pay

NHIS sends a bill showing the amount and the ways to pay. Common options include:

• Bank transfer to the virtual account number on your bill
• Automatic debit from a Korean bank account — the easiest way not to forget, once you have a bank account
• NHIS’s website or app, where you can also check what you owe

Whichever you choose, remember the timing: each month’s premium is due by the 25th of the month before — the January premium by 25 December, for example. Students who think of it as a bill for the month just past are the ones who fall behind without noticing.

If a bill hasn’t arrived, or you’ve missed a payment, contact NHIS straight away. Its foreign-language line is 033-811-2000 (multilingual).

What happens if you don’t pay

There are three separate things to keep apart: the due date, the point at which your coverage is restricted, and what immigration sees when you apply to extend your stay.

Late fees start after the due date. Once the 25th passes, late fees accrue on the overdue amount, so even a short delay costs something.

Coverage is restricted if the premium is still unpaid a month later. Under the standard revised in April 2025, if a premium due by the 25th is still unpaid by the 25th of the following month, your insurance benefits can be restricted from the month after that. For example: the February premium is due on 25 January; if it’s still unpaid on 25 February, coverage can be restricted from March. While coverage is restricted, you pay for treatment yourself. If that happens, pay what you owe and ask NHIS how treatment during that period is handled.

Your extension of stay can be affected. Immigration checks NHIS payment records when you apply to extend your stay (often called a visa extension). Unpaid premiums may affect that application. Clear everything before you apply.

The common causes are mundane: a bill went to an old address, an automatic debit failed when an account changed, or a student assumed a scholarship or the university was paying. If you hold a scholarship, check with its provider whether it covers NHIS.

Can your own insurance replace NHIS?

Not automatically. Holding private insurance from home doesn’t by itself exempt you, and you shouldn’t decide on your own that you’re excluded.

Exclusion from NHIS is possible only in narrow cases — broadly, when you can prove equivalent coverage under a foreign country’s law, a foreign insurance contract, or an employer contract. You apply to NHIS with documents, often including a Korean translation of your policy, and NHIS decides case by case.

Timing matters. Exclusion normally applies from when you apply, but in some circumstances — for example, if you haven’t yet paid a premium, or apply soon after your first payment — it can be backdated to the date you were enrolled, subject to conditions. Because whether and when you’ve paid can affect this, if you’re considering exclusion, contact NHIS early and ask three things together: the deadline for applying, whether to keep paying while it’s reviewed, and whether your exclusion could be backdated. Your international office may also know what NHIS has accepted from students at your university.

Holidays, leaving Korea and family

• Going home for vacation: under the rules, leaving Korea for a month or more can end your enrolment from the day after you leave. If you’re going abroad for that long, ask NHIS before you go how your coverage and premiums will be handled when you return.
• Leaving Korea for good: settle your final premiums before departure. Unpaid amounts remain on your record.
• Spouse or children with you: they’re enrolled under their own rules. Ask NHIS how to register them rather than assuming they’re covered through you.

FAQ

I’m on D-2 and I haven’t received a bill. Am I covered? Possibly — enrolment is tied to your registration, not the bill. Check your status with NHIS, and confirm the address on your Residence Card is current so the bills reach you.

Can I see a doctor before my Residence Card arrives? Yes. Clinics will treat you either way; the question is whether NHIS rates apply. If your enrolment has started, bring your passport and registration receipt and ask whether the clinic can confirm your eligibility. If not, your private or university insurance is what you claim on.

My university says I’m in group insurance. Do I still need NHIS? Yes. University group insurance generally supplements NHIS rather than replacing it. Check your policy’s conditions, including whether it requires your NHIS premiums to be paid up.

Does NHIS cover dental and eye care? Basic treatments are covered with co-payments, but many dental procedures and glasses or contact lenses are partly or fully non-covered. Ask for a price before treatment.

Will the premium change while I’m studying? Very likely, once a year. Your international office will normally post the new amount.

Why a branch may refuse you, what a 한도제한계좌 is, and how to get the limits reviewed

Last updated: September 2026

You have your visa, you have an address, and you have tuition to pay, rent to transfer, and a phone bill waiting. So you walk into a Korean bank, and you are told — politely, and often with real regret — that they can’t open an account for you today.

This is one of the most common administrative surprises for new international students in Korea, and almost nobody arrives expecting it. It is also not personal, not a judgement about you, and not the end of the conversation.

This post explains why the refusal happens, what to bring so that it doesn’t, what a transaction-limited account is and why you may get one first, and how those limits are reviewed later. The ARC guide covers the residence card this all depends on; the D-2 visa guide shows where both sit in your first weeks.

The short answer

• Can you open an account before your Residence Card arrives? Sometimes — but not at every bank or branch.
• What should you expect at first? Often a transaction-limited account (한도제한계좌).
• What should you bring? Passport, Residence Card if issued, proof of enrolment, proof of address, and a Korean phone number.
• Where should you go? Start with the branch your university recommends, ideally one on or beside campus.
• Can the limits be removed later? Yes — through a separate review of your financial purpose and supporting documents.

Why a branch may say no

Korean banks are not being difficult for the sake of it. Two things are happening behind the counter.

Identity and transaction-purpose checks. Korean banks must verify who the customer is and understand the intended use of a new account. If that purpose cannot be documented clearly, the bank may decline to open the account, or open it with transaction limits instead. A newly arrived student with no registration number, no phone contract in their name and no address history may therefore be asked for additional documents before the bank is satisfied that it understands what the account is for.

The 대포통장 problem. Korea has spent years dealing with accounts opened in one person’s name and then sold or handed to someone else for fraud — voice phishing, scam proceeds, gambling payments. Banks and their staff face real consequences when an account they opened turns out to be one of these. The result is a culture of caution that falls hardest on customers who can’t yet document their life here.

So the branch is not asking are you trustworthy? It is asking can I document what this account is for? Everything below is about making that question easy to answer.

The order things have to happen in

New arrivals often try these in the wrong order and get stuck in a loop: the bank wants a Korean phone number, the carrier wants a residence card, immigration takes weeks.

The sequence that usually works:

1. Arrive. Apply for your ARC early — booking the appointment in your first week matters more than anything else on this list.
2. Get a phone number you can receive messages on. A prepaid SIM (선불폰) bought with a passport may let you receive ordinary calls and texts before your Residence Card arrives. It may not support Korean mobile identity verification (본인인증), which many services require. Once the card arrives, ask your carrier whether your registration details need to be updated.
3. Open what you can. Depending on the bank and branch, you may be able to open an account — often with transaction limits — on your passport plus enrolment documents before the card arrives. Or you may be told to come back with the card. Both answers are normal.
4. When the card arrives, go back. Register the card at the branch, then ask what it takes to have your limits reviewed.

If step 3 doesn’t work out, the refusal doesn’t prevent you from trying again once the card arrives. Step 4 is where most students’ accounts become genuinely usable.

What to bring

Bring more than you think you need. A branch that can’t complete one check will often accept another document in its place, and the difference between “come back next week” and “let’s open it now” is frequently one extra piece of paper.

• ☐ Passport (original).
• ☐ Residence Card (ARC) if you have it. If you don’t, bring your immigration receipt (접수증) — and see the note below about what it can and can’t do.
• ☐ Certificate of enrolment (재학증명서), or an admission certificate if the semester hasn’t started. This is your evidence of why you need an account, which is the part the bank has to understand.
• ☐ A Korean phone number registered to you, if the bank requires one. Bring the handset — the branch may send verification messages during registration.
• ☐ Proof of address — dormitory confirmation, lease, or residence provision letter.
• ☐ Anything showing money moving in your life here: a scholarship or stipend notice, a tuition invoice, a lab or teaching assistantship contract, a utility bill. Individually unimpressive, collectively useful.

You do not normally need a Korean seal (도장); a signature is fine at the banks students use.

About the receipt. The immigration receipt proves you have applied for registration. It is not the card, and whether a given bank will act on it is that bank’s decision, not a rule you can look up. If a branch needs documentary proof of registration before the card exists, ask your immigration office whether a certificate of foreign registration (외국인등록 사실증명) can be issued at that stage, and ask the branch whether they accept it. Both answers vary — the ARC guide says the same thing, because it is the same wall in two places.

The transaction-limited account (한도제한계좌)

Here is the part that surprises people who did everything right and still feel shortchanged.

If a bank cannot fully verify the purpose of a new account, it may open the account with transaction limits instead of refusing outright. This is a transaction-limited account — 한도제한계좌 in official usage, also called 금융거래한도계좌 or simply 한도계좌 at some banks — and it applies to Korean and foreign customers alike. It is a real account with your name on it — but transfers and withdrawals are capped, and the caps are lower than you expect.

The basic limits are broadly standardised; the review that removes them is not. As of September 2026, a transaction-limited account at a branch-based bank typically allows up to ₩3 million per day at the counter and ₩1 million per day through an ATM or through internet and mobile banking. Internet-only banks may apply different limits, commonly in the ₩1–2 million range. You can check the current figures in the Financial Services Commission’s notice and on bank pages such as Hana Bank’s guide. What differs much more between banks is the opening requirements, the documents they accept, and the criteria and process for lifting the limits.

Nothing lifts automatically. The card arriving does not lift the limits. Time passing does not, by itself. The account becoming a normal account is a separate review that you request and document.

What this means practically: in your first weeks, a large one-off payment — a housing deposit, a tuition instalment — may exceed what your account can send in a day. Find that out before the deadline. If the payment exceeds your limit, contact the branch before the due date. The bank may require a limit review, additional evidence, or a different payment arrangement; presenting the invoice does not automatically override the account limit.

(Housing deposits in Korea are large enough that this collides with the limits regularly. See How Korean Housing Deposits Work.)

Getting the limits reviewed

Banks lift limits when you can document a continuing, legitimate reason to move money. Every bank keeps its own criteria and its own list of acceptable evidence, so treat what follows as the categories that tend to work rather than a checklist that guarantees anything:

• Enrolment and academic status — a current certificate of enrolment, a tuition invoice or receipt in your name.
• Income or funding — an assistantship or part-time work contract with your employer’s details, a scholarship or stipend award letter, a payslip once one exists.
• Housing — a lease in your name, especially with the deposit and monthly rent stated.
• Ordinary life, documented — utility bills, a phone contract in your name, insurance payments.
• Account activity — some banks may consider an established pattern of ordinary transactions, although transaction history alone may not be sufficient.

How to ask: go to the branch where you opened the account, bring originals, and say plainly what you need to be able to do — I need to pay my landlord ₩500,000 on the 25th of every month. A concrete purpose is much easier for a bank to assess than a general request for higher limits.

Expect a review with an outcome, not a form with a result. Some students get full limits at once; some get a partial increase; some are asked to come back with one more document. A request for additional evidence is not necessarily a final refusal.

Which bank, and which branch

The branch matters more than the bank.

Go to a campus branch if there is one. A branch inside or beside a university, in a city with a large international student population, handles this every March and September. They know which documents exist, they have the forms, and — the underrated part — they have staff who can explain a limited account in English or Chinese.

Ask your international office where students bank. Many universities have a relationship with a specific bank, sometimes with a desk on campus during orientation, sometimes with student ID cards that double as bank cards. Following that path removes most of the friction this post is about.

Major banks — Shinhan, Woori, KB Kookmin, Hana, NH Nonghyup, IBK — all serve foreign residents, and several run dedicated foreign-customer desks and multilingual apps. Differences between them matter far less than the branch you walk into.

Internet-only banks (Kakao Bank, Toss Bank, K Bank) are a moving target. Eligibility for foreign residents, and which documents their app-based verification will accept, have changed repeatedly and can differ from what a friend experienced last year. Check the bank’s own current notice rather than a forum post. The practical advice: open a branch account first, and treat an internet-only account as a convenience to add later.

After it’s open

Register electronic banking deliberately. Internet and mobile banking, a security card or OTP, and a certificate (금융인증서 / 공동인증서) are separate registrations. Do them at the counter while someone can help; doing it alone in an app later, in Korean, is a bad afternoon.

Get the debit card (체크카드). Ask whether it’s issued on the spot or mailed, and whether your account limits affect card use.

Plan on a debit card first. Credit-card approval can be difficult for students without regular Korean income or domestic credit history. A Korean debit card covers most everyday payments, although some deposits, instalment purchases and overseas transactions may require a credit card or a separately enabled card.

Fix identity verification (본인인증) early. Korean apps — payments, delivery, tickets, government portals — verify you through your phone, and this generally works when the name and registration details held by your carrier match your Residence Card exactly. If verification keeps failing, that mismatch is the first thing to check, at the carrier rather than the bank.

Link Open Banking (오픈뱅킹) once your account is normal, so you can see and move money between accounts from one app.

Sending and receiving money abroad

Sending money abroad may require additional checks depending on the amount, your residence status, the source of the funds and the purpose of the transfer. Requirements can also differ between a bank transfer and a licensed remittance provider, and some banks handle certain transfers only through a designated foreign-exchange bank account. Before making a large or time-sensitive transfer, ask the provider exactly which identification and supporting documents it requires. Bring your card, your passport, and your enrolment or funding documents.

Receiving money from abroad is usually straightforward: give the sender your bank’s SWIFT code, the branch, your account number, and your name exactly as the bank holds it — mismatched names are the usual cause of a delayed incoming transfer. The bank may still contact you if it needs to confirm the sender, the source, or the purpose of a transfer.

Compare what a transfer actually costs. Bank wire fees, the exchange rate spread, and the receiving bank’s charge are three separate costs, and the cheapest advertised fee is not always the cheapest transfer. Licensed non-bank remittance providers operate in Korea and are often cheaper for smaller amounts; they need the same kind of identity documents you needed at the bank.

If you’re refused

Ask exactly what was missing. Not why can’t I open an account, but which document would let you open it? The answer is usually specific and obtainable.

Come back with what they asked for. A refusal at one branch does not necessarily mean every branch or bank will refuse you, but the productive next step is the missing document rather than a different door.

Then try a campus branch familiar with international students, or ask your international office to call ahead. Some will send someone with you. A Korean-speaking friend helps less than you’d think with policy and more than you’d think with the ten minutes of explanation around it.

If the answer is “after your ARC,” that is a real answer and not a brush-off. Use a prepaid SIM and a cash buffer in the meantime, and plan any large payment around the gap.

Before you leave Korea

Decide whether you still need the account — for refunds, final bills, or a future return. Deposits, insurance and utility refunds sometimes arrive after your flight, and if you’re coming back on the same registration, keeping the account may be simpler than reopening one.

If you close it, move the remaining balance out first, and do it while you can still visit the branch. If you keep it, ask how the bank handles dormancy, what happens when your Residence Card expires, whether you’ll be able to log in from abroad, and how your certificates get renewed.

FAQ

Can I open an account without an ARC? Sometimes, often with transaction limits, depending on the bank and the branch. Bring your passport, enrolment documents, a Korean phone number and proof of address, and ask. If the answer is no, it is not a permanent no.

Why is my transfer limit so low when I have a perfectly normal account? Because it is probably a 한도제한계좌. The basic daily limits are broadly standardised; lifting them is a documented review you have to request.

How long until my limits are lifted? There is no standard period, which is why no honest guide gives you one. It depends on the bank’s criteria and the documents you can show.

Can someone else pay my tuition or deposit for me? Sometimes — but confirm the procedure with the university or the landlord first. A third party may be allowed to transfer money to your assigned account, provided the payment can be matched to you. What you must not do is borrow another person’s account, card, password or banking credentials, or route unexplained funds through someone else’s account.

Do I need a Korean seal? No — a signature is accepted at the banks students use.

Which bank is best for international students? The one with a branch on or beside your campus, staffed by people who did this fifty times last March.

None of this is about being trusted. It’s about being documentable — and every document the bank wants is one you can get. If a branch asked you for something this guide didn’t mention, tell me and the next version will have it.

What Most Embassies Require — and What Depends on Your Country

Last updated: September 2026

Korea has a national baseline for D-2 visa applications, but there is no single checklist that works unchanged at every embassy or consulate. The Korea Visa Portal sets out the basic requirements; your local mission may add country-, residence-, or case-specific documents. Throughout this guide, mission means the embassy or consulate handling your application.

That’s why two students with the same admission letter get different instructions, and why forum threads contradict each other without anyone lying. Your own mission’s published checklist is the final word. This guide is the thing to read before it: the common core, the areas that vary most, and how to read your mission’s page so you only make the trip once.

For how the visa fits together end to end — what’s sequential, what you can do in parallel, what happens after you land — see the D-2 visa guide.

The short answer

• Where is the authoritative list? The Korean embassy or consulate with jurisdiction over you.
• What should you check first? Whether your academic documents need authentication. If they do, that’s the slowest item, and it doesn’t wait for anything else.
• What comes from the university? The Certificate of Admission (표준입학허가서), and the university’s business registration certificate where required.
• What varies most by country? Authentication, translation, financial proof, and health documents.
• What arrives at the end? Not a passport sticker — a Visa Grant Notice you print and carry.

What comes from where

Document area	Usually provided by	What may vary
Application, photo, passport	Applicant	Form version, photo size, passport validity
Admission documents	University	Original or copy, business registration certificate
Academic records	School or issuing authority	Apostille, legalization, transcript, translation
Financial proof	Applicant, parent or sponsor	Minimum balance, holding period, issue date
TB certificate	Designated hospital	Nationality, residence, visa length, approved clinic

The core list

Almost every mission asks for these. Prepare clear scans and copies of all documents, and submit originals only where the checklist requires them.

• ☐ Visa application form, completed and signed. Use the form your mission publishes, not one you found elsewhere.
• ☐ Passport photo in the size your mission specifies, taken recently against a plain background. Photo specifications differ between missions more often than people expect — check before you print.
• ☐ A passport valid for at least the minimum period stated by your mission, often six months or more, plus a photocopy of the bio page. Some missions also want copies of previous Korean visas or entry stamps if you’ve been to Korea before.
• ☐ Certificate of Admission (표준입학허가서) issued by your university. This is the standardized form the mission needs; a general acceptance letter is not a substitute. When it’s issued depends on the university — usually tied to a tuition deposit, sometimes to another step — so ask your admissions office what triggers it.
• ☐ A copy of the university’s business registration certificate (사업자등록증), where required. The university provides this; ask the international office if it wasn’t in your admission packet.
• ☐ Proof of your highest completed education, in the form required by your mission. An apostille, consular legalization, certified copy, or transcript may be required depending on where the document was issued and where you apply — see the next section, because this is where most of the delay lives.
• ☐ Financial documents showing you can fund your studies and stay.
• ☐ Application fee, in the form your mission accepts. Fees differ by nationality and visa type under reciprocity arrangements, and some nationals are exempt, so read the fee line on your mission’s page rather than budgeting from a figure someone quoted online.
• ☐ Anything your mission adds. Missions add and waive documents at their discretion — a study plan, a CV, proof of relationship for family-funded applicants, a police certificate, a self-introduction. If it’s on their list, it’s required; if it isn’t, don’t submit it uninvited.

Keep a complete digital copy of the whole set before you hand anything over. You will need the same categories of document again at extension time, and having last year’s file saves a week.

Four document areas that vary most

1. Authentication: apostille, legalization, or something else

Many missions require your diploma and transcript to be authenticated. Not all of them, and not in the same form — so the first question is whether authentication is required at all, and in what form.

If it is, the route usually turns on the country where the document was issued, not on your nationality:

• If the issuing country is covered by the Hague Apostille Convention — Korea has been a party since 2007 — an apostille from that country’s designated authority is normally the correct route. That authority is often the foreign ministry, sometimes a court or a state office.
• If it isn’t, the usual route is consular legalization: certification by that country’s authorities, then confirmation by the Korean embassy or consulate there (영사확인).
• Some missions accept or require something else — a certified copy, a transcript sent directly by the issuing institution, or verification through a designated body.

Membership of the convention changes, so check the issuing country’s current status on the HCCH status table rather than a list copied from a forum.

Two practical points. First, if authentication is required, do it first. It is measured in weeks, occasionally months, and it is a common reason students miss a semester. Second, check what gets authenticated — some missions want the diploma only, some want the transcript too, and if your school issues digital documents, ask how the authenticating authority handles them.

Some missions additionally require academic credentials to be verified through a designated body rather than, or in addition to, authentication — this comes up for degrees from particular countries. If your mission’s page mentions a verification institution, treat that as a separate lead time on top of everything above.

2. Translation

If your documents aren’t in Korean or English, expect to submit translations — and expect rules about who may translate them. Some missions accept a translation by a professional agency with a stamp; some require notarization; some require the translation to be authenticated along with the original. Ask before paying a translator, because a translation that doesn’t meet the form requirement is a document you’ll buy twice.

3. Financial proof

This is the item where quoted numbers do the most damage. Your mission’s requirement is not one figure but four separate specifications: the balance, the statement period, the holding period (if any), and how recently the certificate must be issued. The D-2 visa guide breaks those four questions down, and a dedicated post on financial-capacity review is coming.

Three things students routinely get wrong here:

• Your university’s financial document is not the mission’s. Some universities require their own proof at the admission stage, with its own date requirements. You may need two originals.
• A scholarship letter doesn’t automatically replace a bank statement. Some missions accept it instead; others want both. Ask.
• A sponsor’s account is not always acceptable on its own. Where it is, missions usually want proof of the relationship and sometimes a notarized sponsorship letter.

Related: what studying in Korea actually costs, which is the number your funding plan should be built around.

4. Health documents

Applicants from certain countries must submit a tuberculosis test certificate from a hospital designated by the Korean government — not any clinic. If your country is on that list, find the designated hospital early; appointment availability, not the test, is the bottleneck. Whether the same certificate is needed again at the registration stage in Korea depends on your immigration office, which the ARC guide covers.

How to read your mission’s checklist

Find the right mission first. Jurisdiction is normally your country of nationality, or a country where you hold legal long-term residence — and missions state their own rules on whom they accept. The wrong consulate’s checklist is a correct checklist for someone else. Korea’s overseas missions are listed on the government’s embassy directory.

Match your exact status code. D-2 has sub-categories: D-2-1 through D-2-8, assigned by your university from your program. Requirements, forms, and even the length of stay granted can differ between them — a short-term exchange or language-track applicant is not a doctoral candidate.

Read the four columns people skip: original or copy, whether it must be authenticated, how recently it must have been issued, and whether it must be in Korean or English. Most files sent back for correction fail on one of these four, not on a missing document.

Check how the mission accepts applications. Appointment-only, walk-in on set days, by post, or only through a designated agency — this varies, and so does whether a family member can submit on your behalf.

Know what approval looks like. Korea no longer puts visa stickers in passports. You’ll receive a Visa Grant Notice (사증발급확인서) to print and carry with your passport, with a window inside which you must enter Korea. Also note there is a separate route in which the university applies in Korea for a Certificate of Visa Issuance Confirmation on your behalf — if your international office mentions this, follow their instructions rather than the standard consular sequence; the timeline post covers that path.

The order that saves weeks

1. Day of admission: check immediately whether authentication of your diploma and transcript is required. If it is, start that process first — nothing else has a longer lead time.
2. Same week: ask the international office two questions — when is the Certificate of Admission issued, and what triggers it? and which financial document do you need from me, and by when?
3. Same week: open your mission’s checklist and note the four columns above for every line item.
4. Same week: check appointment availability. In busy seasons, you may need to reserve a slot before every document has arrived.
5. In parallel: passport validity, photos, business registration certificate, translations, TB test if applicable.
6. When the Certificate of Admission arrives: submit. Processing times vary by mission and lengthen before semester start.
7. On approval: print the Visa Grant Notice, check the entry window, and book flights inside it.

The visa guide shows where each of these sits in the larger timeline, and a post on the admission-to-visa timeline is coming.

Why files get sent back

Common reasons for document resubmission or delayed review include:

• Name mismatches. Your passport, diploma, bank certificate and admission form must agree — including middle names, transliteration and the order of names. Even a minor inconsistency can delay review.
• A document that’s too old. Bank certificates and family documents often have an issued-within window. They expire quietly.
• Academic documents in the wrong form — unauthenticated where authentication was required, or authentication on the wrong document.
• A financial statement covering the wrong period. A recent large deposit may also require explanation if the mission asks for transaction history or a minimum holding period.
• Photo specification. Size, background, or age of the photo.
• A missing university document — most often the business registration certificate, because students assume the mission already has it.

None of these are judgements about you, and all of them are fixable — but each fix costs a cycle of processing time, which is the one thing you can’t buy back before a semester starts.

Once you land

The documents don’t stop at the border, they just change hands. If your authorized stay exceeds 90 days, you will generally need to register for a Residence Card within 90 days of arrival — see Getting Your ARC in Korea. Shortly after that you’ll be asked for the same enrolment and address documents again, this time by a bank: Opening a bank account in Korea.

FAQ

Is there one official list of D-2 documents? There is a national baseline on the Korea Visa Portal, and then your mission’s own list, which is the one that binds you.

Do I need an apostille? Only if your embassy or consulate requires your academic documents to be authenticated. If authentication is required and the country where the document was issued is covered by the Apostille Convention, an apostille is usually the correct route. Otherwise, follow the legalization or verification process specified by your mission.

Can I apply with a general acceptance letter instead of the Certificate of Admission? No. Missions want the standardized certificate issued by the university.

How much money do I need to show? It depends on your mission and your university, and on four separate specifications rather than one number — balance, statement period, holding period, and how recent the certificate is.

Do I need a criminal record certificate? It isn’t part of the standard D-2 core, but some missions request additional documents. Your mission’s list decides.

Will I get a visa sticker in my passport? No — a Visa Grant Notice to print and carry, with an entry window to respect.

Checklists are boring right up until one line costs you a semester. If your mission asked for something this list doesn’t have, tell me which mission and which document — that’s exactly how this page gets better.

Last updated: September 2026

If you’re staying in Korea for more than 90 days, you register as a foreign resident at the immigration office for your area, within 90 days of arrival. What you receive is the 외국인등록증 — printed in English as Residence Card, and called the ARC by nearly everyone. It carries your foreign registration number (외국인등록번호), the 13-digit ID that banks, carriers, hospitals, and government portals use to identify you.

The D-2 visa guide shows where registration sits in your first weeks. This post is the registration itself: booking, documents, the visit, the wait, and — the part most guides skip — what you still need to check with each bank and carrier after the card arrives. Because the card confirms your registration; it doesn’t, by itself, complete anyone else’s paperwork.

Two waits, not one

It helps to know from the start that there are two separate waiting periods, and they don’t overlap:

• Waiting for an appointment. Slots at immigration offices in university cities fill quickly in March and September. Booking in your first week is the single most useful thing you can do.
• Waiting for the card after your visit — typically a few weeks, longer at semester peaks.

Guides that say “about three weeks” are usually counting only the second one. Plan for both.

Step 1 — Book, and know what booking isn’t

Reservations are made at hikorea.go.kr through the visit reservation (방문예약) menu; the site runs in English and Chinese. Two rules that aren’t obvious from the interface:

• Book at the office with jurisdiction over your address. Each office serves a fixed list of districts. The one with the earliest slot, or the one nearest campus, is not necessarily yours.
• Most offices don’t take walk-ins at busy times. Some keep limited capacity; in a university city at semester start, treat the reservation as required.

A reservation is not a registration. The legal duty is to register within 90 days of arrival; booking a slot doesn’t pause that clock. If the earliest available date falls after your 90-day deadline, don’t simply book it and wait — contact your immigration office or the Immigration Contact Center (☎ 1345, multilingual) before the deadline and ask how to proceed.

Ask about group registration. Many universities collect documents from new international students and submit them together at semester start, on the school’s schedule and by the school’s method. This spares you the individual booking scramble; it does not necessarily make the card arrive sooner, and university batches can take longer to process. Ask your international office which route they recommend for your intake.

Step 2 — Documents

The standard set for a D-2 student. Your office or university may add to it, so check Hi Korea’s list for your status before the visit.

• ☐ Integrated application form (통합신청서) — downloadable from Hi Korea, also available at the office.
• ☐ Passport — bring the original. Whether a photocopy is also required varies by office; bringing one costs nothing.
• ☐ One color photo, 3.5 × 4.5 cm — taken within the last six months, facing forward, white or plain background, face fully visible. Any photo that meets the official specification is fine; Korean ID-photo booths (증명사진) know the format if you need a new one.
• ☐ Fee: ₩35,000 (raised from ₩30,000 in January 2025). If you choose delivery by registered mail instead of pickup, the postage is charged separately.
• ☐ Certificate of enrollment (재학증명서). If you’re registering before the semester officially starts, your portal may not issue one yet — ask your international office what they provide instead (an admission certificate or a letter is common).
• ☐ Proof of residence. Which document depends on where you live: a dormitory confirmation from the university; a housing lease (임대차계약서) with the address and the landlord’s signature; or, if you’re staying with someone, a residence provision letter (숙소제공확인서) with that person’s details. Each has its own requirements — a lease missing the landlord’s signature is the classic reason a residence document is rejected.

Tuberculosis test certificate. Nationals of certain countries must submit one from a designated hospital. If you’re from a listed country, you most likely provided this at the visa stage; whether you need to submit it again for registration depends on your office and your documentation, so confirm on Hi Korea or with your international office beforehand rather than at the counter.

Step 3 — The visit

The appointment is short: documents across the counter, fingerprints scanned, fee paid. When you submit, you’ll be asked how you want to receive the card — pickup at the office or registered mail to your address. Decide before you go.

You’ll leave with a receipt (접수증) confirming your application. Keep it. It shows you’ve applied, which matters if anyone asks about your status. It is not the card, and most banks and carriers won’t treat it as one. If a bank, employer, or landlord needs proof of registration before the card arrives, ask your immigration office whether a certificate of foreign registration (외국인등록 사실증명) can be issued at that stage — and ask the institution whether they accept it. Both answers vary.

Step 4 — The wait

Card production typically takes a few weeks, longer at semester peaks when offices are processing large numbers of students. This is normal and not something you can speed up after the fact — which is why booking early matters.

You can move during the wait, but two things follow. First, once registered, any change of residence must be reported within 15 days of moving in (at the immigration office, through Hi Korea, or at a community service center). Second, if you chose mail delivery and you move before it arrives, the card goes to the old address. If a move is likely, choose in-person pickup when you submit; if you’ve already applied and then move, contact your office promptly to update your address and confirm where the card will be sent.

(About to sign a one-room lease? Korean housing deposits work differently from most countries — see How Korean Housing Deposits Work.)

When the card arrives — check, then update

Check the card. Name spelling, date of birth, visa status, and the expiry date of your period of stay. If anything is wrong, contact the office that issued it.

Update what you’ve already opened. If you opened a limited account on your passport or bought a prepaid SIM in the first weeks, those records don’t update themselves. Take the card to your bank branch and carrier so they register your number. Conditions like transfer limits and internet-banking access are set by each bank under its own rules and are not automatically changed when you present the card — ask what applies to your account. Same with 본인인증: it works when the name and number registered with your carrier match your card exactly, so if verification fails after you have the card, that mismatch is the first thing to check.

Mobile Residence Card. Korea issues a mobile Residence Card (모바일 외국인등록증) through the government’s Mobile ID (모바일 신분증) app; it’s an official form of ID, not just a convenience, and it’s issued by tapping an IC-chip card to your phone or via a QR code at issuance. Banks and other services have begun accepting it for identity checks, including account opening at some banks, but support varies by service — ask before relying on it. The physical card comes first.

If things go wrong

You lose the card. Report the loss and apply for reissue at your immigration office within 14 days. The reissue fee is ₩35,000. Ask when you apply how the replacement will be delivered; if you’ve moved, update your address at the same visit.

You’re past the 90 days. Contact your immigration office or 1345 right away and follow their instructions. A late registration carries a fine that depends on how late, but registering late is far better than not registering, which puts your status at risk.

Your documents are refused at the counter. Usually the photo or the residence document. Ask the officer whether you can submit the corrected document later without a new appointment, or whether you need to rebook. Practices differ by office, and asking on the spot can save you the reservation wait.

FAQ

Can I walk in without an appointment? At most offices during busy periods, no. Some keep limited walk-in capacity; in a university city at semester start, book on Hi Korea.

Do I have to carry the ARC? Foreign residents are required to carry the Residence Card or passport and present it when asked. In practice the card lives in your wallet and the passport stays somewhere safe.

How much is the fine for registering late? It depends on how late, which is why there’s no single number here. If you’re past the deadline, contact your office now rather than calculating.

Is the number on the receipt usable? The receipt confirms you applied. Whether any institution can use your registration before the card arrives is up to that institution; ask them, and ask your office about a certificate of foreign registration if you need documentary proof.

Nothing here is exotic — just the sequence, and the checks that don’t happen on their own. If your registration hit a snag this guide didn’t cover, tell me; the next version will cover it.

Last updated: September 2026, checked against Ministry of Justice / Hi Korea notices and Korean embassy guidance current at that date. Immigration rules change often; a companion post tracking those changes is coming._

Official sources on the Korean student visa are accurate about the rules. What they rarely explain is how the pieces connect — which document unlocks which, what you can prepare in parallel, and what happens after you land. I work inside a Korean university and help international graduate students with exactly these steps, and this guide is the map I wish they’d had.

We’ll follow the visa’s full life: getting it, landing with it, keeping it, and what it can become after graduation. Details that depend on your country or your university are in their own posts; this one shows you where they fit.

What the D-2 Is — and What It Isn’t

The D-2 visa is for students enrolled at Korean higher-education institutions. Its sub-categories follow your program: D-2-1 (associate), D-2-2 (bachelor’s), D-2-3 (master’s), D-2-4 (doctoral), D-2-5 (research), D-2-6 (exchange), D-2-7 (work-study linked programs), and D-2-8 (visiting student, under one year). Your university assigns the sub-category from your enrollment; you don’t choose it.

What the D-2 is not: a language-study visa. If you’re going to a Korean Language Institute first, that’s the D-4 — different rules and different work rights. Moving from D-4 to D-2 after admission to a degree program is a status change that can be done inside Korea.

→ D-4 vs D-2: Language Visa vs Degree Visa Explained (coming soon)

Two checks to run before you pay a deposit

1. Is the university, and your specific program, currently restricted from issuing student visas? Each year the Ministries of Education and Justice designate institutions whose visa issuance is limited because of problems in managing international students. For the year starting with the fall 2026 semester, this covers 16 institutions for degree programs and 4 for language programs. Restrictions apply by program type, so a university can be restricted for language trainees but not degree students, or the reverse. The current list is published by the Ministry of Education and reflected on the Study in Korea portal; your consulate can also confirm it.

2. Does the university hold accreditation (인증대학)? This is a separate scheme from the restriction list. Accreditation is a quality certification for managing international students, and it can simplify parts of the visa process — for instance, some embassies apply lighter financial-document requirements to accredited universities. Not being accredited does not by itself block a visa. It’s worth knowing your university’s status because it changes what your embassy will ask for.

Getting the Visa: What Depends on What

The D-2 process has a few steps that really are sequential, and a larger set of documents you can prepare at any time. Keeping them apart saves weeks.

The sequential part

Admission → Certificate of Admission (표준입학허가서, COA). The COA is a standardized Ministry of Justice form issued by your university, and it’s the document the embassy needs to see. When it’s issued depends on the university: many issue it after the tuition deposit is paid, some on a different schedule, and scholarship or exchange arrangements often follow their own rules. Ask your admissions office when the COA is issued and what triggers it — that answer sets your timeline more than anything else.

COA → Embassy application. Once the COA is in hand, you apply at the Korean embassy or consulate that has jurisdiction over you — normally your home country, or a country where you hold legal long-term residence (embassies state their own rules on who they accept). A fresh D-2 is generally not applied for from inside Korea; the main in-Korea route is a status change, such as D-4 to D-2.

Application → Visa Grant Notice. Korea no longer places visa stickers in passports. Approval arrives as a Visa Grant Notice (사증발급확인서) that you print and carry with your passport. Processing time varies widely by post — some embassies quote a few working days, others several weeks, and all of them slow down in the weeks before a semester starts — so check your embassy’s stated time rather than assuming. The notice has a validity window for entry (commonly around 90 days); enter Korea within it.

→ From Admission Letter to Visa: Timeline + What Can Go Wrong (coming soon)

The part you can prepare in parallel

None of these wait for the COA. Start them the day you’re admitted, or earlier.

• Passport with enough validity for your program, plus passport photos in the size your embassy specifies.
• Highest diploma and transcript, authenticated the way your embassy requires — apostille where your country is in the Hague convention, consular legalization where it isn’t. This is the slowest item for many applicants; start it first.
• Financial documents — see below.
• University business registration certificate (사업자등록증). The university provides this; ask if it’s not in your admission packet.
• Health documents, if your embassy requires them. A tuberculosis test certificate from a designated hospital is the common one, required for applicants from certain countries.
• Anything specific to your embassy. Embassies add and waive documents at their discretion; their published checklist is the final word.

→ Visa Documents Checklist by Country

Financial proof: four questions, not one number

You’ll see a figure — often around ₩20,000,000 — quoted as “the” requirement. Treat that as a reference point, not a rule. Embassies differ, and they differ on more than the amount. Before you assemble anything, get answers to four questions from your embassy’s checklist and your university’s admission guide:

1. What balance must the account show?
2. What statement period do they want — some ask for the last three months of transactions, others six.
3. How long must the funds have been held, if there’s a holding requirement at all?
4. How recently must the certificate be issued — within two weeks of applying, within a month?

Two more things to confirm. First, some universities require their own financial document at the admission stage, separate from the embassy’s — so you may need two originals with different dates. Second, if you hold a scholarship, don’t assume the award letter replaces bank documents: some consulates accept it in place of them, others require a bank statement in addition. Ask.

After You Land: The Registration Chain

The visa gets you into the country. What makes you a functioning resident is a short chain of registrations that begins on arrival.

1. Residence Card (외국인등록증, “ARC”). Apply at the immigration office for your area within 90 days of arrival. The issuance fee is ₩35,000 (raised from ₩30,000 in January 2025). Appointment slots in university cities fill quickly at the start of each semester, so book early, and expect the card itself to take some weeks after your visit. Full walkthrough: Getting Your ARC in Korea.

2. Bank account and phone. Both are far easier with the ARC, and identity verification (본인인증) on Korean websites generally depends on a Korean phone number registered in your name. Before the card arrives, you can still get by: many banks offer limited accounts on a passport, and prepaid SIM options exist for the first weeks. What you’re waiting for is the full set — a regular account, a contract phone, and verification — and each provider’s conditions differ, so ask before assuming you’re blocked.

→ Why Korean Banks Reject Foreign Students (+ How to Open an Account) · Korean Phone Numbers & 본인인증

3. National Health Insurance (NHIS). Enrollment is mandatory for international students and happens automatically — on D-2, from your date of foreign registration on first entry; for language students on D-4-1, after six months in Korea. What is not automatic is payment: premiums are billed monthly, and you need to set up how you’ll pay them (automatic transfer from a Korean account is the usual choice once you have one). Unpaid premiums can affect your application to extend your stay.

→ NHIS Health Insurance for Students · Your First 30 Days in Korea

Keeping the Visa

A D-2 is conditional on your enrollment, and the conditions are checked at extension time. Here’s what to know and when.

• Enrollment, attendance, and academic standing. Universities report attendance and status to immigration. Falling below attendance thresholds or being placed on academic probation can affect your extension. If you’re considering a leave of absence, talk to your international office first — your enrollment is the legal basis of your stay.
• Extensions. D-2 status is granted for up to two years at a time. Extending means enrollment proof, attendance records, and financial documents again — the same categories as your original application, so keep copies of everything.
• Part-time work needs a permit. Work is allowed with a permit (체류자격외활동허가), within hour limits tied to your program level and Korean proficiency, and outside certain excluded job categories. The rules have specific conditions and change periodically, so they live in their own guide.
• Report a change of address within 15 days. If you move, you must file a change of residence (체류지 변경 신고) within 15 days of moving in — at the immigration office, through Hi Korea, or at a community service center (주민센터). Late reporting carries a fine.

After Graduation: Where the D-2 Can Lead

Graduates who meet the requirements can apply for the D-10 job-seeking visa. Following a December 2025 change, graduates of Korean universities can stay on a D-10 for up to three years in total, extended one year at a time. From a D-10, a job offer that meets the criteria can support an application for an E-7 work visa — an application with its own requirements on the job, the employer, and your qualifications, not an automatic conversion. Korean policy has been widening these routes, and they’re worth planning for from your first year.

FAQ

How long does the D-2 take? At the embassy, anywhere from a few working days to several weeks depending on the post — check your embassy’s stated processing time. End to end, count on two to four months, because the COA, document authentication, and financial statements each have their own lead times. Work backwards from your semester start.

How much money do I need to show? It depends on your embassy and your university, and on four separate things: balance, statement period, holding period, and how recent the certificate must be. Get all four from your embassy’s checklist before you prepare anything.

Can I apply from inside Korea? A new D-2, generally no — it goes through the embassy with jurisdiction over you. The common in-Korea route is a status change, most often D-4 to D-2 after admission.

Can I work on a D-2? Yes, with a work permit obtained separately, within the hour limits, and never before the permit is issued.

What if I take a leave of absence or my attendance drops? Your enrollment is what your visa rests on, so both affect it. Ask your international office before you act, not after.
