I sent all of the required documents along with my N-400 already. Yesterday I finally got my interview appt. letter and N-659 (Interview Document Check List) where, of course, they want all those documents I already sent in. Do I go and make another pile of this papers and take them with me? I'm sure its better play it safe and take them, even that they should have all of them there, together with my application.

What did you do?

Thanks for help!

It is always the safe thing to do, to bring copies and the origionals of every thing sent in, so the IO can look at the origionals, and keep a copy of anything for the file.
