thank you for the information!!! Did you get it in two days like the SETV? You have to exit every 60 days but can this be done in Mae Sai within the same day? I have everything but a letter saying I need ME. Mostly I have a family and it may be easier to do this than two back to back SETV with three RT flights out and back.
Search my posts in this forum. You can get a 60 day SETV for Thailand in Bali. Easy as pie. I posted very detailed info on this process two months ago.
