I am in the process of moving from to Florida. Went on a trip and opened a bank account through agent. Returned home and deposited the 800k in the account. Went back to Thailand 3 months later and applied for retirement visa through agent. Took 30 days and was approved. Had to return to US for routine medical appointments. Will return to Thailand in February for the long term. BTW , I FOUND Korean Air to be the most comfortable and one of the shortest flights (26-27 hours with transfers. Fly to Atlanta the Korea then Bangkok.
Going through this now for retirement visa. Came 5 months ago on visa exempt opened a bank account. Deposited the 800k thb it must be in the bank 2 MONTHS.
returned last week and submitted application for retirement visa. Just waiting for approval and return of my passport.
