To make this case more complicated: Say that said someone had two passports (of the same country) - only one passport associated with said visa. Could / should this someone maybe use the other passport for the 30 day exempt, first, and then fly out, and return on the other passport with the Thai visa? Or would changing passports in between raise more red flags then it would benefit the case?
So I guess, just not present the eVisa and see what kind of stamp is issued. If 30 day exemption, that visa should still be valid. If 60 days, the IO used up the single entry visa.
I recently got a METV with providing just a one way flight. As for the requirement to demonstrate need for multiple entry … I sent them a picture of the car and motorcycle to be used for crossing land borders. But every consulate and every immigration office is different in Thailand. They like to make their own rules up.
Unfortunately, yes. Visa exemption runs - especially via DMK airport are not advised. I got extorted there once returning on visa exempt after two weeks in Bali. Ever since I do visa instead of visa exemption. Doesn’t guarantee entry either, but makes it less likely to run into such trouble. It is such a swampy mess how they make up rules on the go. Given that there is no written law about any maximum amounts or comulating amounts of stay on tourist visa or visa exempts until this day.
Everybody can BUY a motorbike. Question is, whether you can register it in your own name. IF you can get a "residence certificate" on your mode of entry (almost everywhere except Bangkok), in most cases the answer is yes.
