I am an American in Thailand on an OA retirement visa that expires Jan 2, 2022. I opened my FCD and savings bank account in my name on Feb 1st 2021. I have transferred over 100,000 baht into my account every month beginning in Feb. I do not intend on leaving Thailand prior to Jan 2, 2022. Will I need 800,000 baht in the bank to extend for another year or can I use the monthly method albeit less than 12 months?
Thank you in advance.
