I'm flying into BKK tomorrow via Japan from the US. The last time I entered (via Saigon) the Immigration Officer cautioned me about numerous use of VOA but didn't put the warning stamp in my passport.
I visit 2 times a year... 3 at most. Is there any formal restriction on this? Saigon trip was the first "Visa Run" I've ever made. Most of the time it's back and forth to the US.
Thanks for the add
TLDR : Answer Summary
The original poster (OP) is inquiring about any formal restrictions on frequent visa-exempt entries into Thailand, as they travel multiple times a year. Community responses indicate that there are no strict limits for Americans entering Thailand under visa exemptions, although it can depend on the immigration officer's discretion. Suggestions include considering alternatives like the METV visa for longer stays, especially if the OP is married to a Thai national. Others caution about having necessary documents ready for immigration and the current travel restrictions due to external circumstances.
