Can we filed our jointly income tax with one ITIN expired?Even though that person doesn't have an income?

We are in the process of getting our SSNs, but it's getting longer than we expected. I didn't renewed my ITIN because in doing so, I would have to send my only ID on the mail, and would it take about 2 months to getting it back; I didn't want to risk losing it and it was so much needed for my process. My lawyer advised me to wait for my SSN, so my husband and I filed for an extension, which will expired soon. My husband's ITIN is still valid and he is the only source of income. We don't know what to do if I don't received my SSN before the due date to filed the extension. Please, advice.
