On my I-797c Request for Applicant to appear for initial interview it says that I should bring all "Original and copy of each supporting document the you submitted with your application". What documents are they referring to? Do they mean everyrthing from the very beginning of the K1 process?
Most people bring an exact replica of the AOS package and the K1 packet (I-129F), with all the proof of relationship stuff. Technically the agent should already have these on hand, but there are rare cases where they don't. I suggest you bring everything you can. It's always better to be safe than sorry.
