Has anyone come across this problem yet. According to immigration, affidavits have to be given now to prove that the passport holder and person named on a degree certificate are the same. It seems the British embassy will not do affidavits for this. Although they called it an affidavit at the time. They gave a letter which Thai immigration will not accept. Trying to convert a 60 day tourist visa into a non b here, which has always been possible. Any ideas how to fix this without having to go back to the U.K. for a non. b there?
