American visa F 1 has expired, can Seoul still enter the country?

China citizens can apply for transit visas from Incheon Airport Customs as long as they hold valid visas from the United States, Canada, Australia, New Zealand, Japan and 30 European countries, pass through South Korea and issue exit tickets to third countries. Those who meet the requirements are allowed to transit for up to 30 days.

You must have a valid F/KLOC-0 visa and a return ticket to transfer in Korea, and you must have a visa-free entry permit. The specific number of days depends on the time given by the immigration officer at the time of entry. When the customs goes through the formalities, they need to show their joint ticket and travel to travel itinerary.

South Korea's requirements for visa-free stay for China passport holders F 1 are:

Visa F 1 is valid.

If your American visa expires and you want to go back to China, you should still be able to stay in Korea for a few days. Especially in the hands of South Korean border officials.
