Hi I have a uk passport and I'm flying to Thailand in February and plan to stay for just under 2 months.
I have a couple of questions.
Will I get granted a visa at arrival?
Would I be able to fly to Vietnam and come straight back in to Thailand within those 60 days or do I need to apply for a specific multiple entry visa?
Thanks in advance
TLDR : Answer Summary
As a UK passport holder, you can enter Thailand without a visa under the visa exemption policy for up to 60 days. For your stay of just under 2 months, you will not receive a visa on arrival but will get an entry stamp for the duration permitted. If you plan to visit Vietnam during your stay, it is possible to return to Thailand after that trip, provided you follow the rules. A multiple-entry visa or a re-entry permit is not required for a simple trip to Vietnam and back, but it's essential to ensure there are no overlaps with your stay limitations.
