keep in mind

that if you are getting a new yearly extension from an existing one where you are using banked money method (the 800K baht in a thai bank account in your name only) you also need the bank to print out a year's detail transaction history.
This is to show that last year you kept the 800K baht in the account for 3 months after the extension was issued, and then never let the balance below 400K baht the rest of the year before you put it back to 8 two months before you apply for this new extension.
This only has to be done on a straight savings account, not a fixed deposit one where you leave the money in all year.
