Hello filed for my mum in March, 2019 and I got an RFE for late registration of birth certifcate. Secondary documents were requested. However, I could only get school records. Even with that The school could only write a letter showing the name of my parent, my date of birth, place of birth and house address they had on file when I was a student. They also gave me a copy of my certificate of completion they had on file.
I had my uncle and aunt write affidavits confirming the relationship with my mum. I also opted for a DNA Test through the USCIS recommended lab.
Will these documents be sufficient to prove the relationship between my mum and I?
PS: I did not include baptismal or medical records as we lost those documents in a flood. And the clinic I was born is no longer operating.
