About:24-Hour Visa-Free Transit
US-Seoul-Shanghai-US itinerary eligible for 240-hour
Is a flight connection through a third country sufficient to be eligible for a transit itinerary? I am a US national traveling to Shanghai for a one-week business meeting. Is the following itinerary eligible for the 240-hour visa-free transit policy: (1) US to Seoul, (2) Seoul to Shanghai, (3) Shanghai to the US?
I have a 6-hour layover in Seoul with a change of airlines. Do I need to enter S. Korea during my layover in Seoul?
