The Alien Registration Card (Residence Card) in Korea

It is the single most important piece of paper in your first months. Get it within 90 days, and almost everything else (bank, phone, insurance) opens up.

If you are staying in Korea longer than 90 days, you must register with immigration and receive a residence card. Most people still call it the alien registration card, or ARC, and you will see both names everywhere. The government officially renamed it the residence card in 2021, but the function is identical: it is your legal ID inside Korea, tied to your visa, and it is required for a bank account, a long-term phone plan, health insurance, and almost every other adult task.

TL;DR
  • Register within 90 days of arrival. Missing the deadline can mean a fine.
  • Book a slot on HiKorea first. Walk-ins are generally not accepted; you reserve a time, then submit documents in person at your local immigration office.
  • "ARC" and "residence card" are the same thing. The name changed in 2021; the document did not.
  • The card unlocks everything else. Bank account, long-term phone contract, and health insurance all key off it.
  • It takes a few weeks to arrive. Use a prepaid SIM and a passport-only bank account in the meantime if you need them sooner.

The 90-day rule

You must apply for your residence card within 90 days of entering Korea. This is a legal deadline, not a suggestion, and applying late can result in a fine. The safest approach is to treat it as a first-month task rather than a 90-day one, because immigration appointment slots can book out and processing itself takes time.

What you need

Exact requirements vary slightly by office and nationality, so always confirm against your immigration office's current list. A typical student set includes:

  • Your passport and a copy.
  • The application form (available on HiKorea and at the office).
  • A passport-style photo.
  • Your certificate of enrollment or admission from your university.
  • Proof of your Korean address (a lease, a dormitory confirmation, or a residence document).
  • The fee, paid in revenue stamps at the office (a modest amount, often around KRW 30,000).
  • For some nationalities, a tuberculosis test result from a designated hospital.

Your university's international office almost always runs a briefing on exactly which documents your cohort needs and which immigration office to use. Start there.

The step-by-step process

  1. Settle your address. You need a confirmed place to live and proof of it before you apply.
  2. Get your enrollment certificate from your university.
  3. Make a reservation on HiKorea for your local immigration office.
  4. Submit your documents in person at the appointment and pay the fee.
  5. Collect or receive your card. Processing typically takes a few weeks; some offices mail the card, others have you return to pick it up.

What the card unlocks

Once you have your residence card (and the registration number on it), you can:

Keeping it valid

Your card is tied to your visa, so keep both current. If you move, you must report your new address to immigration (often within 14 days). If you extend or change your visa, the card is updated to match. Carry it or keep a clear photo of it; it is your ID in Korea.

What to do next

  1. Read the Life in Korea overview for how this fits the wider settling-in sequence.
  2. Once your card arrives, open a bank account.
  3. Confirm your health insurance enrollment.

Frequently asked questions

How long do I have to register for an alien registration card in Korea?
You must apply within 90 days of entering Korea. Applying late can result in a fine, so most students treat it as a first-month task. Appointment slots and processing both take time, so book your HiKorea reservation early.
Is the alien registration card the same as the residence card?
Yes. The government officially renamed the alien registration card the residence card in 2021, but the function is the same and both names are still used everywhere. It is your legal ID in Korea, tied to your visa.
How do I apply for an ARC as a student?
Settle your address and get your enrollment certificate, make a reservation on HiKorea for your local immigration office, then submit your passport, application form, photo, enrollment certificate, proof of address, and the fee in person. Some nationalities also need a tuberculosis test. Many universities run a group application for new students.
How long does it take to get the residence card?
After you submit your documents, processing typically takes a few weeks. Some offices mail the card to you; others have you return to collect it. In the meantime, use a prepaid SIM and, if needed, a basic passport-only bank account.
What can I do before my residence card arrives?
You can get a prepaid SIM with just your passport for an immediate phone number, and some banks offer a limited passport-only account. Full banking, a long-term phone contract, and confirmed health insurance generally wait until the card and your registration number are issued.
