Q1. It is a form that they give you that, basically, says that you agree with the conditions that you receive your extension. Q2. Yes. Q3. Did it first thing in the morning. Take out 100 baht at ATM, then update passbook so that it shows current date. Get a copy of all pages of your passbook. Go inside bank and ask for an Immigration letter that will show how long you’ve had the account and the current balance. Cost me 100 baht.
