Can I Extend My Multi-Entry Visa Before Traveling to Bali?

Now just so you know, you apply for the 90 day Non-O visa based on being over 50 by meeting the requirements in Jomtien THEN you wait for 14 days while the application is under consideration (and you cannot leave the country during this time) then you go back and get the Non-O visa and a new 90 day stamp inked into your passport, THEN you wait until you have 30 days or less left on that 90 day stamp and apply for a year extension again by meeting the requirements.

The requirement for banked money when applying for the in country 90 day Non-O visa in Jomtien is that the 800K baht doesn't need to be in the bank any length of time BUT you do need to prove it was transferred in from outside the country.

The requirements for banked money when applying for the year extension at Jomtien (and all the other offices) is that the 800K baht be in a thai bank account in your name only for 2 months BEFORE you apply for the extension
