Personally,
@Jona****
, I'd go back on the year extension (if you could), all you'd need to do is meet the requirements and you'd get another year marriage extension
AND
you can legally work on it too.
To answer your question, I think you'd have to go to your immigration office with someone from your employer to find out IF they can meet the requirements to get a 90 day Non-B issued inside the country and if you could apply for it from covid extensions from a marriage extension.
