@John *******
no issue at all coming here on a single entry tourist visa
Enter get 60 days
get the bank account open and the 800K baht transferred in
go apply for the initial 90 day Non-O at your immigration office when you have between 15 and 21 days left on your stamp pay 2000baht
application goes under review for 14 to 20 days depending on the office
go back on that date, get the Non-O visa and new 90 day stamp inked in
once the funds are seasoned in the account for 2 months go apply for the year extension for 1900baht, the extension is issued on the spot
buy a re-entry permit if you want to exit/re-enter during the year the extension is valid for
***NOTE, I believe ONLY Jomtien requires the funds to be seasoned the 2 months before you apply for the Non-O visa itself, all the other offices only require the funds be in thai bank account in your name transferred in from abroad on the date you apply.
So once you get here, get the account open get the funds transferred in GO to your immigration office, talk to them and get the hand out for the 90 day Non-O visa documentation requirements.
