I know it is late there and I might not find anyone who can help me with my questions regarding entry visas. I hold a passport from the USA and am intending on arriving in Thailand around the end of the month. I have heard/read/researched so many varieties of the requirements and differences between the OA and the O. I am focusing on the O visa for now. I plan on coming in-country and just getting the tourist visa then going through the process of applying for the O. I am 74 and do NOT meet the financial requirements that I have read about. I am close, but not quite. I just watched a year-old video on Vagabond Buddha that said the O visa did not require an insurance policy. I have so much conflicting information on how to extend any of these types of visas including the basic tourist visa. (I read that the Thai government is cracking down on border runs, etc.) Any advice would be appreciated. I had thought about getting a work visa as I have been teaching English in Brazil for the last 15 years and am fully certified to do so...but my age seems to be an issue....ug.
