@Ken *******
there is no visa/extension that requires the money to be left in the account for 2 months after you get an extension
The seasoning for extensions is like this
-Retirement; 2 months before, 3 months after (then not lower than 400K for the rest of the year)
-Marriage; 2 months before (some offices also want the funds left one month after until the under consideration stamp runs out)
-Raising thai children; no seasoning time
-Raising foreign children; 500K in an account for 30 days before the first year and 3 months for every year after that
