You might consider the Non O Retirement visa via the Thai consulate in Los Angeles. No insurance required. You need to show funds in USA equivalent to 800k baht then….. You will need to open a bank account in Thailand and deposit 800,000 baht in order to obtain one year extensions of stay.
The 1). bank letter of account ownership and 2). the statement, can be a few days old. 3) The bankbook must be updated on the day of application. I just did my annual extension to my 90 day non o here in Chiang Mai.
If you are holding 800k baht in a bank account, may I suggest you re enter Thailand visa exempt and then immediately apply for a 90 day Non O visa in Thailand. Then, extend it for a year at the appropriate time. The Non O does not require health insurance and might save you some money that you will spend on insurance premiums.
I just got my first one year extension to my non o (retirement) visa in Chiang Mai last month. Immigration wanted to see the bank letter as you describe but only wanted a six month statement which I obtained at the Bangkok Bank branch at central airport plaza on the spot with no waiting.
You say you are getting a new visa stamp on Friday. Do you mean an extension? If you’re getting an extension at an immigration office on Friday…consider getting your reentry permit at the immigration office at the same time and avoid getting it at the airport.
