I got following RFE
Submit any secondary evidence in your possession to support the information you have provided about your birth and parentage. Secondary evidence will be evaluated for authenticity and credibility. Such evidence may take the form of historical evidence and must have been issued contemporaneously with the event which it documents. Such evidence may include, but is not limited to, medical records, school records, and religious documents. Affidavits may also be accepted provided that they are sworn to by persons who were born at the time of and who have personal knowledge of the event to which to which they attest. Any affidavits must contain the affiant’s full name and address, date and place of birth, relationship to the party on whose behalf they are attesting, if any, and complete details concerning how the affiant acquired knowledge of the event.
Can anybody give their input about the documents required to fulfill the RFE
