it's the extention that creates the problem entering, not the exemption. You can travel in and out of Thailand multiple time in a year, just as long as you do extend your trip every time. Also limited to 150 days pr calender year
Thomas Tohnan if you don't max your stay with extention, it will be fine. Even with 10 trips at 3 or 4 days each time, he will be regarded as a tourist.. It's not that group Immigration trying to target 😊
So according to the rules, you are permitted to enter after January 1st, as a new calendar year.. But have read several posts that claim this will not be the case... Not sure if it's visa agents that are persistent this will not work, but maybe worth a try entering after January 1st?
