I am from the United States. I’m here on a tourist stamp. I have already gone to immigration office in Khon Kaen to get my 30 day extension. I am working on applying for a non immigration O marriage visa. My wife is a Thai national. We have been working on getting the paperwork ready and have our USA marriage certificate translated to Thai. My appointment in Bangkok to get it certificate at the Department of Consular Affairs next Tuesday the 15th. My extension stamp expires on September 7th. I’ve heard everything has to be done or filed 21 days before my stamp expires. It doesn’t look like I’m going to make it. Can I do a border run or any advice would be appreciated. The long holiday sure didn’t help.
