Alien registration: do it within 90 days of arrival
Last checked: 2026-11-10
This is general information. Rules and criteria can change and differ by situation, so confirm the latest details on HiKorea or with your school's international office before applying. It is not legal advice.
Students staying in Korea longer than 90 days register as foreigners and receive an Alien Registration Card (ARC). It is the first step before a bank account, a phone plan and health insurance.
When and where?
Register within 90 days of entering Korea at your local immigration office. Many universities help or give group guidance, so ask your international office first.
Many offices need a visit reservation through HiKorea. The booking process can differ by office.
Documents you usually need
- Original passport and a standard-size photo
- Integrated application form (from the immigration office or HiKorea)
- Certificate of enrollment (or admission letter)
- Proof of address: dormitory confirmation, lease contract, etc.
- The fee (payment methods are explained at the office)
Requirements vary by school, nationality and office. Follow your school's guide and HiKorea for the exact list.
After registering
- Receive your ARC: usually by mail or in person, and it takes some time.
- Report address changes within the required period, including a move between dormitories.
- Health insurance, bank, phone: all easier with an ARC.
- Prepare your extension before your stay period ends.
Common mistakes
- Missing the 90 days and paying a fine
- Forgetting proof of address, such as a dormitory certificate
- Forgetting to report a new address after moving
- Visiting without a reservation and being turned away
