- Immigration checks are rigorous, and individual travelers (but not sightseeing groups) may be required to present documents or samples explaining the reason for entering the country, so please be prepared.
- Passengers who are deemed by the Korean government to be Korean nationals, or foreigners living in Korea in possession of an alien registration card, are not required to complete an arrivals card.
Foreign nationals who do not possess alien registration cards are still required to submit an arrivals card.
