International travelers in transit at Incheon International Airport with a layover of 72 hours or less can tour Korea without a standard issued entry visa starting May 1.
The system began its trial period on October 29, 2012 and has proven beneficial. Foreign nationals who are transferring at Incheon International Airport to a third country are eligible for an official entry permit to the country when they sign up for a transit tourism program designated by the Ministry of Culture, Sports and Tourism.
As a precautionary measure, immigration assistants will accompany transit passengers throughout the entire stopover period, helping them through immigration procedures safely while they enjoy sightseeing during their scheduled layover. There is a fee of 10,000 won for participating in the assistance service.
