US Citizen living in Hua Hin for one year on the non immigrant O-A visa. I'm interested in converting to the Non O visa (which doesn't require health insurance). I am planning a trip to vietnam to cancel my O-A and will re-enter on the 90 day/ 1 year retirement O visa plan. I have 65,000 baht international transfer into my Thai bank for twelve months however I read that because I am voiding my O-A visa when I leave the country the 12 month track record of bank receipts will no longer be valid- requiring me to start over. Any verification of this? TIA
