No advice. It’s experience. Tbh I’m kinda tired of seeing a group of ppl on here who seem similar scaring ppl. If I listened to what I’ve read in this group I probably wouldn’t have applied for a DTV. I came back in twice and was never asked for a ticket upon arrival in Bangkok airport. You can’t disagree with my experience
I have never had a problem when I re entered infact the two times I have entered back into Thai they never asked me for one. Sometimes they do at the departing airport but I haven’t been asked for the DTV since I’ve been using it
