What are the requirements for transferring funds for a retirement visa application in Thailand?

Remember, If you are applying for your initial Non-O retirement visa in Thailand, you need to have 800K in your bank account when you apply for a visa (not 1-year extension). 65K monthly bank transfer wouldn't meet the in-country Non-O requirement. 65K * 12 months makes 780K.

1.It does matter. IF you want to use the 12 months of monthly deposits the money must come from a foreign bank account and it must show the international transfer code in your bank book.

That is why many people had problems with wise transfers as they often came as domestic transfer and that is NOT allowed by Immigration.

The holder of the foreign bank account is not shown and of no interest.

shouldn't matter at all and in fact won't even show that on your bank book where it shows the transaction code

nope, no requirement to do anything but transfer in 65K baht a month to the account for the previous 12 months before you apply for a year extension. you can pull it out as soon as you want to, there is no minimum balance you need to keep

your foreign spouse would have to get a Non-O 90 day visa outside the country from a thai consulate AFTER you have your year extension (most consulates won't issue it until the spouse that meets the requirements has the year extension)
