Where can I find the forms for a marriage visa in Thailand?

You can take air asia or nok air's fly-n-ride program to Mukdahan OR you can drive your car into Lao under the restrictions outlined by David Broadfoot below

Good Luck (y)

To get a year-long, multi-entry Non-Immigrant Type O visa based on marriage to a thai from the consulate in Savannakhet you need

the original marriage certificate (if married in thailand it's the one with the rose border)

copies of:

front&back of the marriage certificate

front&back of your thai wife's i/d card

thai wife's house book listing

data page of your passport

lao visa and entry stamp

(you sign everything with your name on it and your wife signs everything with her name on it meaning you BOTH sign the marriage certificate copies)

you need 2 passport sized photos and the filled out application along with 5000baht. You turn in your application one morning before 11:30 and you pick up your passport the next afternoon after 1:30

and where would you be getting this marriage visa?
