What are the reporting requirements and re-entry process for a Non-O marriage multiple visa holder in Thailand?

IF he decides not to exit the country after the 90 day stamp is running out he has two choices, take a 60 day visit thai family extension at the immigration office for 1900baht OR apply for a year extension by meeting the requirements of 400K baht in a thai bank account in his name for 2 months.

Those are the only 2 extensions available to him.

I think you and your husband misunderstand how that visa works 😮 And just to be sure this is a visa issued based on being married to a thai national right?

A year-long, multi-entry Non-Immigrant type O visa is VALID for a year from the date it's issued <- meaning you can enter/exit all you want during the validity of the visa

BUT

You don't get stamped IN to the country for a year on that visa. 🙁

That visa gets you a 90 day entry stamp each entry, when that 90 days runs out you exit/re-enter the country to get another 90 day entry stamp. You do that every 90 days for the validity of the visa.

There is no reporting on that visa because he cannot longer than 90 days on any of the entry stamps he gets from the visa
