Okay,
@Ri**
I think you need to LOOK at the little red entry stamp you got when you stamped IN to the country. Unless I'm wrong you only got stamped in for 90 days AND on that stamp you don't do 90 day reporting AND you can't do a border bounce which leaves you with a stamp that is running out :O
You have three options for an extension (good news is all extensions cost the same 1900baht ;) ) :
Option 1:
you meet the financial requirements (400K baht in a thai bank account in your name only for 2 months before you apply for your extension) and apply for a year extension based on marriage
Option 2:
you apply for a 60 day visit thai family extension <- which you can do ONCE per entry. This doesn't have any financial requirements
Option 3:
you apply for a 60 day covid 19 extension <- which you can do until May 29th
IF you can't meet the requirements to get the year extension, I'd go for the covid extension and then use that time to find a way to meet the requirements so you can apply for a yearly extension based on marriage.
The days of bouncing out and back in on a multi-entry Non-O to get another 90 days is long gone and I doubt that it's gonna come back for a good while.
