We are preparing our documents for i-485 and I have seen that people have had issues if the parents names are spelt differently, Last Names have changed or some documents have full names or some have initials.
In my case, my father’s name has been spelt fully in my passport but in my birth certificate his first name and middle name are given by an initial.
Also, in my mother’s case, my birth certificate has my mother’s last name as her married last name and my birth certificate has her maiden name. Mother is no more.
What proof, documents or affidavits can I provide to support that they are the same people.
