I'm currently on 30 day extension of 60 day tourist visa issued in US and expires next week. I plan on taking a flight to Vietnam on the exit by date and return the same day through Suvarnabhumi. Never had back to back entries into Thailand, but did have a visa exempt entry in September and November last year.
Should I have any issues reentering? I want to book a monthly airbnb home base but thinking to wait until after I gain reentry into BKK.
