Submit Secondary Evidence
If the birth certificate is considered unreliable due to late registration, USCIS allows secondary evidence to prove the parent-child relationship.
Common Types of Secondary Evidence:
Baptismal Certificates
School Records showing your name and parents’ names.
Medical Records (prenatal, postnatal, hospital records).
Immunization Records
Early childhood records (like clinic cards).
Government-issued documents listing your parents (passport applications, national ID registrations).
Affidavits from people who have direct knowledge of your birth and parent-child relationship (e.g., relatives, family friends, community leaders).
The RFE letter you receive will also request secondary evidence to support your late-registered birth certificate. Submit those documents and keep us updated on how it goes. Good luck.
