An Argentinian friend of us got rejected at Mae Sai border one week ago. They didn't let him leave Thailand. He had one day left on his visa exemption. So the next day he flew to KL for a week and came back to Chiang Mai.
He was at the border with his gf. The female thai immigration officer asked if they are both together than she came out of her both and showed them the sign saying no more visa runs. She started to shout and told them to talk to immigration. Than they got their passports back. They both have Argentinian passports which gives them 90 day visa exemption.
Are there any other reports like that?
