Hello All.... I'm currently in the UK and hold a one year Non Immigrant O ME visa. I am about to fly back to Bangkok. Will I need to show evidence of onward travel or a return ticket....? I haven't got a re-entry permit with it being a multi-entry visa. .... Thanks...
TLDR : Answer Summary
If you hold a Non-Immigrant O ME multiple-entry visa and it is valid, you do not need to provide evidence of onward travel or a return ticket when entering Thailand. You can simply show your valid visa during check-in and at immigration.
