Foreigner registration (외국인등록) in your first 90 days: documents, fees and what to know

Foreigners planning to stay in Korea for 91 days or longer must complete foreigner registration (외국인등록) and be issued a residence card — formerly called the ARC (Alien Registration Card), now officially renamed the Residence Card, though most people still call it the 외국인등록증 or ARC. Deadline: within 90 days from the date of entry (counted from the entry stamp in your passport, NOT the date you signed a housing lease or started working).

Basic documents: application form (통합신청서), passport, ID photo, proof of residence, and documents for your visa type (employment contract, certificate of admission, etc.). Book an appointment in advance on HiKorea (hikorea.go.kr) at the immigration office in charge of the area where you live.

Fee: about 30,000–35,000₩ (some sources list 30,000₩, others 35,000₩ — confirm the exact amount on HiKorea or at the counter when you apply).

Processing time: usually about 2–3 weeks; you receive the card afterward (pick it up in person or by mail, depending on the office).

Important note: residing without registering on time can lead to fines (under the Immigration Act 출입국관리법, fines can reach millions of won, and serious cases may face heavier penalties). Register early within the 90 days to avoid problems with future extensions or changes of status.
