Sorry, just out of interest, US passport, 50-plus of age:
Suppose during visits to Thailand you managed to open a Thai bank account in y'r name. Then you transfered international 65k฿-plus into that account for at least 12 months. After that you bought a NON IMM O visa, based on Retirement in the US and after arriving in Thailand AND after 60 days you ask for a year extension based on retirement, can you use these 12 international transfers instead of 800k฿ (2 months before already deposited) on the bank ? I'm a bit confused because I read many times that for the first year extension you need that 800k฿ in the bank. Thanks !
