You will need to get it switched to your new passport before you leave the country, otherwise you will have to start the process all over again. Make sure you get a re-entry permit before you leave the country so that your visa is still valid when you land back into Thailand
after you have come into Thailand 2 times in 2026 you will need to get a visa the 3rd time I think. People with more knowledge might know if I am correct or not.
GiftedFish5406 it means you can only come twice in 1 year on a visa exempt. First exempt you will get a 30 day extension and the second exempt you will only get 7 days extension in Thailand. After that you will be refused or get a visa.
If you get a new passport like I did, you have to do your 90 day reporting in person to the immigration office first time round,then you can do the 90 day reporting online from the second time
