I applied for my parents in September 2019, finger printing is done and we have received a RFE for I 485. Both have Domicile Certificates, School Leaving Certificates - which states their place of birth - but does not state their parents name ( I guess in 1960's it was not a norm to have parents name in such documents). Also if we check the US Dept of State - Visa Reciprocity and Civil Document link shows that there were no Birth Certificates prior to 1970. As mentioned below - is this a sufficient enough evidence that there are no birth certificates available at the time of my parents birth?
I would prefer you to get a non-availability certificate along with two affidavits from people who were alive when your parents were born. That is what I would recommend. FAQ in detail...
