Your parents’ citizenship status doesn’t affect your eligibility for federal student aid. In fact, the FAFSA form doesn’t even ask about parent citizenship status. The information provided on the FAFSA does not go to any other agency, it is used ONLY for determining your eligibility for federal aid.
If your parent doesn’t have a Social Security number (SSN), you’ll need to enter all zeros without dashes (000000000) in the parent SSN section on your FAFSA form.
Also, a parent who doesn’t have an SSN can’t create an account username and password (FSA ID) or complete their part of the FAFSA form online. They can sign the FAFSA form only if you print a signature page. To do this, select “Print Signature Page” on the “My FAFSA” or “Signature Status” page, sign and have your parent sign, then mail it to the address listed on the page. Your FAFSA form will be processed once the signature page is received.
