Information about your parent?

I'm filling Form I-485 with my spouse. Per Part 4 - Information About Your Parents, should I fill my father A on my birth certificate or my step father B? I have father A's name on my birth certificate and step father B's name on my marriage certificate. Thanks guys!

Interesting question and who better to answer it but yourself. I also don’t understand when you say your step father is on marriage certificate, do you mean when you were filling out forms you used his name ? Because only the married couples name is on the actual certificate.

Please use your biological dad’s name. This has nothing to do with your step father unless he legally because your father and documents have been sign. Don’t get on USCIS bad side

I would put your birth father in the main application. And the in the additional information page at the end, put down your step father's information.
