I-130 Question that I cannot find the answer to

[jharman]

Hi everyone,

I am the petitioner for my wife. We are in the process of completing that I-130 but I am stuck on a question about my parents. I have a biological father that I have never met. I dont know his birthday or anything about him. I was raised by my step-father since I was 2. I have his last name but he has never adopted me or anything like that. My bio father's name is on my birth cert. So, I really dont know what to do. I know that I can submit my passport instead of birth cert but what will happen when they dig further?

I think you should put your biological father, and put "unknown" for any questions you don't know the answer to.
