Whether you’re an expat, student, or long-term visitor in Korea, getting your Alien Registration Card (ARC) is a key part of settling in. But the process can be confusing. Here are 7 of the most common questions foreigners ask about the ARC — answered clearly and concisely.
1. Do I Need an ARC for Short-Term Visits?
If you’re staying in Korea less than 90 days, you usually don’t need an ARC.
But for stays over 90 days, you’re legally required to apply within 90 days of arrival.
This includes:
- International students
- English teachers
- Spouses of Korean nationals
- Long-term business visa holders
2. Can I Leave Korea Without an ARC?
If you haven’t received your ARC yet but have already applied, you’ll need to get a re-entry permit to leave and return to Korea.
If you already have your ARC, you may exit and re-enter freely as long as the card is valid.
Leaving without it may cause problems with immigration and future visas.
3. What Happens If I Overstay Without Registering?
Failing to register for an ARC within 90 days can result in:
- Overstay penalties
- Fines
- Possible deportation
The fine can range from KRW 100,000 to 1,000,000 depending on how long you’ve overstayed.
4. Do Children of Korean Nationals Need to Register?
If the child holds a foreign nationality, they are still required to register for an ARC just like any other foreigner — even if one or both parents are Korean citizens.
5. Can I Live Without the Card While I Wait?
Once you apply, there is usually a 3–4 week wait before you receive the physical card.
In the meantime:
- You can live and work legally
- A confirmation of application receipt may help with some services
However, many official processes still require the actual card.
6. What If I Lose My ARC?
You must report the loss to immigration within 14 days and request a replacement.
You’ll need:
- A police report
- Passport
- Application form
- Fee (around KRW 30,000)
7. What If You Move?
You must report a change of address within 14 days of moving.
Failure to do so can result in a fine of up to KRW 1,000,000.
You can usually update your address at your local immigration office or district office (gu-cheong).
The ARC is your essential ID while living in Korea. Keep it:
