If you have an Alien Registration and you move, you must report your new address within a set deadline. This isn't just a mailing-address change but a legal reporting duty reflected in immigration residence management, and missing it can bring a fine.
Deadline
Registered foreigners (ARC holders) must report within 15 days of moving in, while domestic-residence registrants like F-4 holders are sometimes guided to a tighter 14 days. Some old online notices say '14 days,' so use 15 days for registered foreigners and 14 days for F-4 to be safe.
Three ways to report
- HiKorea online: when within the 15-day window with documents ready, usually processed within 3 days; not available once the deadline passes
- Community center or district office: the simplest, usually processed on the spot
- Immigration office: for when online is blocked or special cases; appointment-based, so confirm ahead
Documents
Your ARC, the address-change report form, and proof of residence (lease, receipt, etc.) are the common essentials. A passport may be required depending on the case (especially at the immigration office), so bring it along to be safe.
