Jeremy Miller In my calculation, example, If you have a non o visa at the date of 20. January 2026. And you enter to Thailand at 21.Jaunary. 2025. from this date, 21.Jaunary, 90 days is counting. So you open a bank account in a thai bank and put the money of 800,000 Thb into that account. You have 800,000 THB on the date of 30.Jaunary in a thai bank. So you wait for 60 days or two month. after about 60 days, on 1. April, you applied to extend one year and You get it after weeks or something. Let me say, you get extension on 15. April. This means, your extension will expire on 14th. April in 2027. So you put
*****
THB into your bank from April.2026. and every month, then, from April 2026 to April 2027. You have 12 months regular transfer of
*****
THB. every month. so, you can use monthly method for that extension in April 2027.
