The very first thing every international student arriving in Korea needs to do is obtain an Alien Registration Card (ARC). Without an ARC, you cannot open a bank account, enroll in health insurance, get a SIM card plan, or apply for a part-time work permit. Under Article 31 of the Immigration Act, anyone staying in Korea for more than 90 days must apply within 90 days of entry. Missing this deadline can result in a fine of up to 10,000,000 won.
This is especially important for students starting the 2026 fall semester: orientation, classes, and dormitory move-in all happen at the same time, making it easy to put off alien registration. This guide covers everything — use it to get your ARC done comfortably before the deadline. All D-2 (undergraduate, master's, doctoral, exchange) and D-4 (language training) visa holders are subject to this requirement.
Why Alien Registration Matters — Legal Obligation to Everyday Life
Alien registration is not just a bureaucratic formality. Once you complete it, you receive a 13-digit Alien Registration Number — similar to a Korean resident registration number. Without this number, virtually nothing in Korea can get started: bank accounts, National Health Insurance enrollment, National Pension contributions, part-time work permit applications, library cards, government scholarship applications — all require your Alien Registration Number.
The ARC itself functions as a government-issued ID. Under Article 27 of the Immigration Act, foreigners must present their ARC upon request by immigration or judicial police officers; failure to do so can result in a fine of up to 1,000,000 won. The ARC also reduces the risk of losing your passport, since you can use it for routine ID verification instead.
Your ARC remains valid throughout your visa period and is renewed alongside your visa at each extension. If your registered information changes — name, passport number, address, school — you must report it to the Immigration Office within 15 days.
Situations in Daily Korean Life Where You Need Your Alien Registration Number
- Opening a bank account and setting up internet banking
- Enrolling in National Health Insurance (mandatory for international students after 6 months)
- Applying for a part-time work permit (required document for submission through your university International Office)
- Getting a SIM card or a mobile plan (except prepaid)
- Registering on government portals
- Obtaining a digital certificate
⚠️ 90-Day Deadline — Day 1 Is Your Entry Date
The day you enter Korea counts as Day 1. If you arrive on September 1, the 90th day is November 29. Appointment slots fill up weeks in advance during the September semester rush, so booking your HiKorea appointment within 1-2 weeks of arrival is the single most important step.
HiKorea Appointment Booking — 5-Step Complete Walkthrough
Alien registration requires a prior appointment made via HiKorea (www.hikorea.go.kr) before visiting your local Immigration Office. Walk-ins are often refused or result in long waits with no guarantee of being processed. In September, thousands of international students across the country apply simultaneously — competition for slots is fierce.
HiKorea Appointment: 5 Steps
Switch to the English service. Log in or register using your passport number. Enter your name exactly as it appears on your passport.
From the top navigation, select Civil Services then Visit Reservation and choose Alien Registration as your service type.
Choose based on your school or residential address. If you visit a branch outside your jurisdiction, your application may be refused.
Available dates appear highlighted in green. In September, slots may fill up weeks in advance — always choose the earliest open date.
Enter your personal information and finalize the booking. You will receive an SMS confirmation — take a screenshot and bring it to your appointment.
💡 Check Your University Group Registration Service First!
Universities such as Ewha Womans University, Dongguk University, and Incheon National University offer an on-campus group alien registration service for new international students. This is far more convenient than visiting individually — check your International Office notice board before and after enrollment.
Complete Document Checklist for Alien Registration
A single missing document means same-day rejection and a second visit. Check every item against the list below the evening before your appointment.
📋 Mandatory Documents for D-2 and D-4 Visa Holders (6 Items)
- Original passport — validity must cover your intended stay. Renew first if expiry is approaching.
- Standard Admission Letter or Certificate of Enrollment — issued by your university or language school International Office. D-4 holders submit a language school enrollment certificate.
- Proof of residence — lease agreement, dormitory move-in confirmation, or boarding house contract.
- Passport-size photo — taken within the last 6 months; 3.5 cm x 4.5 cm; white background; front-facing; no glasses; upper body visible.
- Application fee 30,000 won — cash or debit card. Some offices do not accept credit cards.
- Alien Registration Application Form — available in-person at the counter. Recommended to download and print from HiKorea in advance.
📋 Additional Documents (If Applicable)
- TB examination certificate: Required for nationals of high TB-risk countries. Issued by a Ministry of Justice-designated medical institution (including public health centers). Allow 1-3 days for results.
- Health insurance documents: If the National Health Insurance Service has already processed your enrollment, bring the confirmation letter.
- Under age 17: A registration certificate for minors applies; apply within 90 days of your 17th birthday.
No Proof of Residence? Here Is What to Do
If you have not yet moved into your dormitory or signed a lease, a temporary accommodation booking confirmation combined with a temporary address letter from your university International Office may be accepted as a substitute at some offices. Requirements vary by location, so contact your local Immigration Office or call 1345 before visiting.
Immigration Office Visit — Detailed 6-Step On-the-Day Process
Allow approximately 1-2 hours for your entire visit, including waiting time.
Using Your Temporary ID and What to Do After Your ARC Arrives
The Visit Confirmation Letter (Temporary ID) you receive after applying can be used for the following:
- University administration: submit additional documents to the International Office, apply for a student ID, submit scholarship applications
- Bank account opening: IBK Industrial Bank of Korea, Woori Bank, Shinhan Bank, and some other banks allow basic account opening with the Temporary ID (policies vary by bank)
- Health insurance processing: use as proof of alien registration when visiting the National Health Insurance Service
- Prepaid SIM activation: some carriers allow activation with the Temporary ID
Once your physical ARC arrives, store it safely and back up a photo of the front to cloud storage. If lost, replacement requires 30,000 won and a trip to the Immigration Office.
⚠️ Moving? Report Your New Address Within 15 Days!
After moving, you must report your new address to the Immigration Office or your local Community Service Center within 15 days. Failure to do so can result in a fine of up to 1,000,000 won.
Penalties for Missing the 90-Day Deadline
The 90-day alien registration deadline is a strict legal obligation under the Immigration Act. A violation remains permanently on your Korean immigration record and can seriously disadvantage future visa reviews.
| Violation | Penalty (Immigration Act) |
|---|---|
| Failure to register within 90 days | Up to 1 year imprisonment or fine up to 10,000,000 won |
| Failure to carry the ARC | Fine up to 1,000,000 won |
| Failure to report address change within 15 days | Fine up to 1,000,000 won |
| Failure to report other registered information changes | Fine up to 1,000,000 won |
| Visa extension / work visa change / permanent residency application | Violation history may result in review disadvantages |
If the deadline is approaching and you have not yet been able to make an appointment, call the Immigration Call Center immediately (1345) and ask for help.
