How can I convert a 60-day tourist visa to a Non-O visa based on retirement in Thailand?

MAKE YOUR OWN POSTS! I'm shutting this down, because the OP's question has been answered. Thank you.

You show up here on a 60 day tourist visa, you get a thai bank account in your name only opened up, you transfer in from abroad 800K baht and then when you have at least 15 days left on your 60 day entry stamp you go to the Jomtien Immigration office, pay 2000baht and apply for a 90 day Non-O visa based on retirement.

It will go under consideration for 14 days (which is why you need at least 15 days on your stamp when you apply) and then you go back and get the Non-O visa and a new 90 day stamp inked in

THEN you wait until your funds have been in your bank account for 2 months and go apply for the yearly extension at the Jomtien immigration office for 1900baht. They'll issue that on the spot (there is no under consideration period)
