You know the place that does 90 day reports and visa extensions, thats immigration to me not police. different building same guys at the airport, the ones that stamp you in and out, those guys told me that they will be looking for people who had the non b visa and went to covid extensions and think they can do a quick trip to another country, they are trying to close that loop hole, so they advised to come back after 30 days if you are in that position. you dont sound like you have a clue
Immigration on koh phangan, if you were on a non b and went to covid extensions you cant get any more extensions you have to leave and they are saying stay out min 30 days
I went to my local immigration few days ago, my friend who does not speak very much english was in the same boat it sounds, was on non b for a year then covid came, when it came time to renew they wanted 4 thai staff and social etc to be paid so he did not have tihis and went to covid extension when the full covid thing happend, that was march last year, now they say unless he goes back and does his full non b and workpermit etc, which he cant his business is gone he needs to leave before 25th, they will only give him a 7 day extension, they also noted that if he for say went to cambodia and tried to come back on visa exempt or on arrival they would see the covid extensions and his last non b and would not grant him entry , my experience a few days ago
