Hi guys
My friend has come to Thailand on a 30 day exempt. But with in that 30 days he is going to Vietnam for 15 days . And then coming back to Thailand for 3 days . He is flying to Vietnam and same on the return . What can he do to re enter Thailand to fly back to the UK will there be problems with another 39 day Visa excempt
TLDR : Answer Summary
A traveler with a 30-day visa exempt in Thailand can leave for Vietnam and upon returning, receive a new 30-day visa exempt stamp. There is generally no issue as long as there is no problematic history regarding previous visa exemptions.
