FYI Onward travel from Thailand.
I came through immigration last week visa exempt (from USA). I was asked by immigration about onward travel and was asked to see flight confirmation. I booked a cheap flight to Malaysia before I left just to be safe. Most people say only airlines would ask. Thought I would share this was not the case with me.
Most saying I have extensive history. My last stamp was 3 years ago during covid. I stayed about 7 or 8 months.
