My mother recently got a RFE for her I-485 due to absence of a birth certificate. She was born in 1938 in Undivided India. We submitted court affidavits from her surviving siblings but the authorities here have requested a Non Availability of Birth Certificate. We approached the municipal authorities in India but they are giving us a hard time for issuing either a Birth Certificate or, a non-availability certificate as she was born in Undivided India (now Pakistan) and does not have a record of birth in India. Could you please recommend a way out for us in this situation.
