Do I need to register as a foreigner?

What the Law Says

South Korean law requires most foreign nationals to register their residence with immigration authorities. The requirement applies based on nationality, purpose of stay, and length of stay.

Under the Act on Registration of Foreigners, any foreigner aged 18 or older who intends to stay in South Korea for more than 90 days must register with the local immigration office within 90 days of entry.

Foreigners staying less than 90 days (e.g., short-term tourists under visa waiver) are generally exempt — unless they change status or extend their stay beyond 90 days.

Additionally, all foreigners — regardless of stay duration — must report their place of lodging to the local police station or immigration office within 24 hours if staying at a private residence (not a registered hotel or guesthouse).

Statutory Text

Any foreigner who has entered the Republic of Korea and intends to reside therein for more than ninety days shall register his/her residence with the head of the competent immigration office within ninety days from the date of entry.
