I've entered Thailand by air twice in the past 3 months and will enter again in December. But between now and december I need to leave for a few days for a wedding in Vietnam. I read somewhere one can only use the exemption 3x in 6 months by air. Is that correct? If so, I guess I should apply for a re-entry permit for my short trip this month?
I know this question has been asked before but as things tend to change I'm asking again. Thanks everyone.
TLDR : Answer Summary
The user is inquiring about the validity of using a visa exemption for entry into Thailand multiple times within a 6-month period, particularly after having entered twice in the last 3 months and planning another entry in December. They seek clarification on whether a re-entry permit is necessary for a short trip to Vietnam, given the potential limitation of three entries by air within six months. Comments suggest there is no official limit on visa-exempt entries, but caution is advised if authorities suspect continued stay without a visa.
