Document Copies for Green Card Application

[immihelp]

Hello!

I am preparing my documents to apply for the green card, after I got married and I have a couple questions about it.

1. Do document copies need to be notarized?
Example: Married certificate and birth certificate translation.
2. Do document copies require a separate affidavit or have special considerations?

Thank You for your help.
