Good Morning Everyone,
If the TM 6 card is lost, what to do in that case? Please guide me to solve this issue.
Thanks.
TLDR : Answer Summary
If you lose your TM 6 card in Thailand, you should first go to the local police station to file a police report about the loss. After that, visit the immigration office with the police report to obtain a new TM 6 departure card. If you are on a visa that requires you to leave the country periodically, you can simply collect a new TM 6 card at the airport when exiting.
