Hi! For the TR visa and COE is it possible to book a flight out of Thailand to another country than the country of origin / the country from which you travelled to Thailand? For example if you fly from a country in Europe would it be accepted to have a flight ticket out of Thailand to another asian country?
TLDR : Answer Summary
Yes, when traveling on a TR visa with a Certificate of Entry (COE), it is acceptable to book an onward flight to a different country than your country of origin. An onward ticket is sufficient, and it does not need to be a return flight.
