Copies of originals needed for interview? URGENT ADVISE NEEDED

My husband just noticed that the interview letter said he needs copies of all original paperwork to take to his interview tomorrow.

I'm just learning this today in (in the states) and panicking a bit. 

Should I make him go get copies of all the original paperwork or will they make the nesessary copies there?

thanks

I believe that we did make copies and they did keep them for our interview. They didn't make any of their own copies, but they didn't need to because we brought them...

You should have him go make copies.
