visit your Immigration and ask for their handout list of requirements for the application to the "1-year extension of the temporary stay permit based on retirement". Each office has this list. And each Immigration officer will be following this list. Regarding the financial proof: on the morning of the day you want to apply, visit the bank and ask them for the "bank letter of guarantee" (in Thai: Rab Roong Thanakan) which will confirm that a minimum of 800,000 THB has been seasoned for 2 months. Update the bankbook. When leaving the bank with this letter, withdraw asmall amount at their ATM and keep the receipt. Then visit Immigration
