Is it necessary to give a certificate of non availability to the INS if you don't have a birth certificate? I was born in 1969 and my wife in 1971 and we both don't have birth certificates. I have read that if you are born after 1970, then a non availability certificate is not issued from the Indian govt. Then what can we give the INS in case a RFE is issued? We both gave affidavits from our parents while applying for I-485.
