I'm clueless about the 90 day reporting thing. How does it work? You just show up at the nearest immigration and show them your passport? Do you have to fill up a form?
visas have a date of issue. So if you were in Thailand while your evisa got issued then left and re-entered the country using your visa, the immigration officer will be absent to see that you were in Thailand at the time got approved. I hope it's clear enough 😅
