Almost everything else in Korea waits on this one card. Bank account, phone contract, health insurance, part-time work permit — every one of them asks for your Residence Card before it asks for anything else. And the deadline to apply is easy to miscount, because the clock starts when you land, not when your visa was stamped.
The 90-day clock starts the day you land
If you’re staying longer than 90 days, you must register and apply within 90 days of your entry date — the day you cleared immigration, not the day your visa was issued or became valid. Get the visa two months before you fly, assume the 90 days runs from the visa date, and you’ve quietly burned a third of it.
The deadline is rarely what trips people up. Appointments are. You can only apply with a HiKorea booking, and slots at busy immigration offices — Seoul above all, and doubly so when a semester is starting — get taken weeks in advance. Book in your first week or two even if the only opening is a month out. Rescheduling is easy. Conjuring a slot seven days before your deadline is not.
The name changed in 2021 and nobody switched over
The Ministry of Justice dropped the word “alien” back in January 2021, and the document has officially been the Residence Card ever since. In 2023 it got a redesign too — color photo, larger format, and a QR code carrying your registration data.
In practice, though, everyone still says ARC. Immigration staff, employers, bank tellers, landlords, and every forum thread you’ll read. So don’t get thrown when a bank form says “외국인등록증” or an HR person asks for your ARC. Same card, three names, no difference in what it does for you.
What to bring
| Item | Notes |
|---|---|
| Application form | Available in English on HiKorea — fill it in before you go |
| Passport | Original |
| Passport photo | Standard 3.5 × 4.5cm, recent |
| Fee | ₩30,000 in the standard case |
| Proof of address | Lease, dorm confirmation, or similar |
| Visa-specific documents | Varies a lot — employment contract for E-series, certificate of enrollment for D-2, and so on |
That last row is where people get sent home. What counts as sufficient swings hard by visa type, and immigration won’t process a half-complete file. Pull up the document list for your exact visa on HiKorea before the appointment. The generic list is not the list that applies to you.
Then you wait 2–3 weeks
Processing usually runs about two to three weeks after you apply. Those two to three weeks are what quietly wreck a lot of first months in Korea: no finished bank account, no postpaid phone contract, no student work permit application, all at once.
You can work around a lot of it, though. A prepaid SIM gets you a Korean number on your passport alone — see our SIM and eSIM guide — and that’s usually enough to get through the first few weeks. Just don’t schedule anything that hard-requires the physical card until it’s in your hand.
Need data before your card arrives?
A data-only eSIM needs nothing but your passport number, so it works from the day you land through the whole registration wait. We keep a live price comparison across providers, sorted by how long you need it.

Your visa gets you into the country. The Residence Card makes you legible to every system inside it. Korean institutions run on the registration number printed on that card the same way they run on a resident registration number for citizens: it’s the key that banks, insurers, telecoms, and government portals index you by. Without it you’re not banned from those services exactly. You’re just invisible to the systems that provide them.
Which is why the ordering matters. Dozens of “how do I do X in Korea” questions turn out to have the same buried first step, and this card is it.
What comes next
Once your card arrives, the usual order is a bank account, then National Health Insurance (which enrolls you automatically anyway), and if you’re a student, a part-time work permit. If you’re about to sign a lease, read up on protecting your deposit first — that’s the one where mistakes cost real money.
If you’re still mapping out the whole move, our Moving to Korea checklist lays out every step in the order it actually becomes urgent.
If you skim one thing
- You have 90 days from your entry date, not your visa date, and the appointment queue is the real bottleneck. Book early even for a far-off slot.
- Residence Card officially, ARC everywhere else. Same document.
- Budget ₩30,000 and 2–3 weeks of processing, and spend that gap on a prepaid SIM instead of waiting around for the card to show up.
Frequently asked questions
How long do I have to apply for a Residence Card (ARC) in Korea?
You have 90 days from your entry date — the day you actually cleared immigration, not the day your visa was issued. Anyone staying longer than 90 days has to register within that window.
Is the Residence Card the same thing as an ARC?
Yes. The Ministry of Justice dropped the word alien in January 2021 and renamed it the Residence Card, but immigration staff, employers, and banks all still say ARC. Same document either way.
How much does it cost to get an ARC in Korea?
The fee is ₩30,000 in the standard case, paid at the immigration office when you apply.
How long does it take to receive your Residence Card after applying?
Roughly two to three weeks. During that wait you generally cannot finish opening a bank account, sign a postpaid phone contract, or apply for a student work permit, so a prepaid SIM is the usual stopgap.
