I need to know whether I, as a non-citizen, qualify for federal student aid.
I can help you with that. First, it's very important to know that being a non-citizen does not automatically disqualify you for aid.
What would cause me to be ineligible for federal student aid?
Certain types of documentation can disqualify you. Do you only have a Notice of Approval to Apply for Permanent Residence I-171 or I-464?
