Expert Answer: For emergency Advance Parole, USCIS typically requires evidence of the family relationship. If you don’t have your original birth certificate or your mother’s birth certificate, bring any available copies, along with other supporting documents, such as medical records confirming your grandmother’s illness, proof of your relationship with her (family photos, affidavits, etc.), and your valid identification. You can also explain your situation to the USCIS officer during your appointment.
