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 under a visa exemption for 60 days without needing to obtain a visa on arrival. You also have the option to visit Vietnam and re-enter Thailand without any issues, as long as you comply with the immigration rules. Each time you re-enter Thailand, you will be eligible for another 60-day exemption, allowing for a trip to Vietnam and back within your travel plans.
