If you take an international flight to Vietnam, then take a domestic flight, you will complete immigration procedures at the international airport (Noi Bai, Tan Son Nhat...). You need to collect your luggage to complete customs procedures, then take the domestic flight.

According to current policies of Taiwan, China, and South Korea, Vietnamese passengers on transit flights with a waiting time of less than 24 hours, if they only stay in the transit area and do not leave the airport, do not need to apply for a transit visa.

If the Autogate is successfully used, the passenger has completed the procedure and does not need to stamp the Passport. If the Passport needs to be stamped, the passenger can choose to do the Immigration procedure according to the normal process.

Automatic immigration at Japan's international airports is only available to passengers with Japanese nationality.
