@Kent ********
careful, there is no "marriage visa with multiple entry" INSIDE thailand.
You could buy a year long multi-entry VISA based on marriage to a thai from a thai consulate outside thailand. That visa allows you to get stamped in for 90 days with unlimited entries for the year it's valid for
OR
You do it insude the country like this
come here and get a single entry 90 day Non-O visa based on marriage to a thai from the immigration office for 2000baht by banking 400K baht in a thai bank account in your name only, (it goes under review for between 14 to 20 days) then you go back to get the Non-O and new 90 day stamp inked in
Then you wait until your funds have been in the bank for 2 months and have 30 days or less left on that you apply for the year extension for 1900baht, (it goes under consideration for 30 days) then go back get the year extension inked in and THEN you buy a re-entry permit 😮 <- that's how you do it INSIDE the country
