Just arrived yesterday from the US on 90 day non-O supposed to be for marriage. Bangkok Immigration just stamped it for 90 days to Dec 1st and reason was just Non Imm-O. No marriage or retired. I brought it to her attention and she argued that it would be fine. Can I get this fixed at the Udon Thani Immigration? My Visa application was for visiting Thai family for over 60 days and it states that.
