My father was born in India in 1940 and then migrated to Pakistan. I applied for his GC, and USCIS is asking for a certificate on govt letter head that no birth certificate exist. Clearly we can't go to India and get that certificate. Should we go to the Indian embassy/consulate in NYC? Any other ideas/suggestions? We have already furnished an affidavit from his maternal aunt and his school certificate that lists his correct date of birth.
