How long does the 400K baht need to be seasoned when changing from a retirement visa to a marriage visa in Thailand?

Sorry to have deleted the previous responses.

This is why CORRECT terminology is so important.

@Wayne ******

if you've been here 5 years you don't have ANY visa (read your stamp, it should say extension of stay).

Ellie was correct stating you can't change a a VISA issued for one reason to another reason.

BUT

seeing as you're on a yearly extension you CAN change the reason for your extension from retirement to marriage the next time you go for a new extension.

AND

Ellie was also correct in stating you need to meet the seasoning of funds for the current extension based on retirement you're on now if you're using banked money <- meaning you need to keep the 800K baht in the account 3 months after your extension was granted and then the balance can't go below 400K baht the rest of the year. <- Which means you will have no problem with the seasoning for the marriage extension. Which is that the 400K baht funds need to be in the account for 2 months before you apply for your new extension. .. .
