Can I use monthly transfers of 65k baht as proof of funds for a retirement visa extension after an ED visa?

The previous year's monthly transfers of a minimum of 65K baht a month into a thai bank account in your name only WOULD be okay and meet the requirement

BUT

You wouldn't get a Non-O visa

IF you were on an ED visa with a year of 90 day extensions, when you wanted to switch off it to an extension based on retirement you don't need a Non-O visa (you only needed a Non-Immigrant type one and the original ED visa fills that requirements)

All you really are doing is changing the reason for your extension to one from education to one based on retirement.

You get a document from your school stating that on xxx date you stop studying, you go to the immigration office, cancel your current extension, and immediately apply for the year extension based on retirement for 1900baht.

Or leave it in your own bank till 4 months before you apply for retirement visa. You only need the 800k in 2 months before applying for the visa. Why go through hassle of monthly transfers.

Do you actually need to get an ed visa in first place? I know you can't work on a retirement visa but don't think taking classes is an issue. Seems like you'd be wasting money unnecessarily. I could be wrong but that was my understanding

Immigration requires that your bank statements for the past year must show that each month your bt65k+ was received by the Thai bank from an overseas source. If any month is missed, or the amount is less than bt65k, you start all over, and that year won't count. If you can afford it, it is much easier to just leave bt800,000 in a Thai bank account in your name, and never touch it.

As long as you can show 65k/month for the previous 12 calendar months as international transfers you'll be right
