Okay, we got to the bottom of the conundrum on this thread.
The O/P had a year long, multi-entry Non-B visa where they bounced out and back every 90 days.
They were on one of the 90 day entry stamps when the country locked down, they went on amnesty, then on covid extensions and are still on covid extensions.
The reason they couldn't get a yearly extension based on marriage is because their stamps all track back to the 90 day entry stamp from a Non-B visa <- and the rule is you have to apply for at least one extension for the reason you got the visa before you can change the reason.
They never did extend that 90 day Non-B entry based on employment which meant they couldn't get a year long marriage extension from it.
Their only option is to exit/re-enter to 'wipe the slate' and start fresh with either a 30 day visa exempt or a 60 day tourist visa entry.
That would let them apply for first the 90 day Non-O visa based on marriage and then the yearly extension.
Thanx one and all for the helpful suggestions
Good luck to
