Where can I pay the fine for overdue visa at the airport?

The location of the visa late payment fee is decided by the host country. According to the relevant public information, Vietnamese visas in Vietnam for less than 3 days do not need to contact the local immigration bureau, but they have to go to the airport to pay a fine (about $23/day? 500,000 Vietnamese dong) and then get an exit visa to leave Vietnam. Thailand's visa has been overdue for one month, so you need to buy an air ticket to leave the country as soon as possible to avoid the more serious consequences caused by the overdue visa for too long. And to avoid conflicts with the Thai police and relevant departments, prepare for visa overdue fines. On the day of departure, you can leave the country after paying the overdue visa fine at the airport immigration office. No matter how long the Philippine visa expires, you can't pay a fine at the airport. Once the Philippine visa expires at the airport, it cannot leave the country.
