I-130 For parents

[Justagirl]

Hello! So I am filing the I-130 for my parents online.
I am on the part where is asking for additional evidence

• Religious record
• School records
• Census records
• Written statements

which I don’t understand. I already uploaded their marriage certificate and my birth certificate.
can anybody please explain this to me?

thank you.

I got a RFE because my birth was registered 3 years after I was born, so they asked for additional evidence, initially I sent my birth certificate. For the RFE I sent my baptismal certificate which contains my parents name, I also submitted a notarized sworn affidavit from my mother explaining why she registered my birth late, photos, cover letter and my sisters birth certificate because we all registered the same day.
