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.
