Can I apply for a one-year extension based on marriage while on a Non-Immigrant B visa?

@Darren ********

I certainly would wring as much time out of the visa you have now as you can. In fact after you get the last 90 day entry stamp you could even get the 60 day "visit thai family" extension on it for 1900baht at the immigration office because you're married to a thai. BUT I do believe you're gonna hafta go back to a thai consulate and get a 90 day Non-O visa based on marriage (easily gotten from Vientiane or Savannakhet with minimal documentation) before you can apply for a yearly extension of stay.

That would be a year-long, multi-entry Non-B visa from a thai consulate then :/

Unless I am totally mistaken you cannot apply for a yearly extension based on marriage off that visa.

It is no problem to change the reason for an extension from one based on employment to one based on marriage because all you're doing is changing the reason for it

BUT you're not here on ANY extension :(

I have not seen someone on a multi-entry B VISA <- from a thai consulate outside the country who bounces every 90 days be able to apply for a new extension based on marriage off of one.
