@Danai ****
you are not understanding how the new covid program works.
The only people who CANNOT apply are people who entered on a 15 day visa on arrival (which neither you nor your husband did) or people who had a Non-Immigrant type visa (again which neither you nor your husband did).
That means you both can apply for a covid extension on this new program that runs until March 25th
Now, whether you'll get the extension or not is totally up to the immigration officer you're sitting in front of on the day you apply. They don't have to give you the extension and just because you don't want to leave isn't a good enough reason for them to give another 60 days. 😕
All you can do is go apply and see what they say. BUT that is why you were told to have a "plan B" in the works just in case you get denied
