Hi, I’m from the UK and planning to come to Thailand in December. I am staying for a week and then flying to vietnam and then back to Thailand. Am I able to do this on the normal tourist visa or would I need a multiple entry visa?
Thanks
TLDR : Answer Summary
The original poster can enter Thailand without requiring a multiple entry visa. They can utilize a visa-exempt entry for both visits, allowing them a stay of up to 30 days during their return after visiting Vietnam. A standard tourist visa would not be necessary in this case.
