Now, if you are still married you are required to file together within 90 days of your card expiring. You must do this before your card expires, not after. So if it expires in January 2022 you need to file it before January 2022, not 90 days after 2022. There’s a lot of information on the website about what kind of evidence you need to submit but as we were talking about before it’s really just to show them that you got married for love and not for immigration documents.
Now for some reason if you need to file this individually rather than together with your spouse it’s okay if you’re outside that 90 day window. This being the case if you’re divorced, annulled, old spouse has passed away or you were battered by them.
