I’m a US citizen. I believe we have 45 days allowed to visit on passport (it could be 30 days, I have read both). I just had a visa for 60 days which ran out. I’m currently visiting Cambodia. I would like to return to Thailand but I don’t know any of the rules. Can I return after my 30 day trip to Cambodia? And what is the best way to do this? Passport or another Visa? And if I want to stay longer, I see people on here writing about extending their visa (is this a tourist visa?). And what if I marry a Thai woman (currently have girlfriend there)? Can someone please enlighten me? Thank you
