I am a 60- something in the US. I used to live in Roi-et, and am just starting to look into retiring there. I have a couple of basic questions: 1) from reading the info on the LA consulate page, I gather that if I have the 800k banked, I do not need to document monthly income. Correct? 2)since the bank account is required, this should mean I have to come to Thailand on the visa exemption first, then apply? and 3) if I were to start with a non-immigrant type O, can that be renewed or do I just start with O-A? Thank you for any information.
