As far as the documents needed goes, take everything that was listed in the interview letter. I would suggest you to make a file and take everything - ANd make copies, coz they want to retain a copy (especially 1040 tax returns) As far as I can remember, following are the things I took : ( My interview was triggered coz of marriage after filing my 485 - )
1) Interview Appointment Letter
2) I-485 Receipt
3) Recent pay stubs ( I took for the last 3 months)
4) Employment verification letter
5) Joint Home/lease document showing the spouse name
6) Credit card statements - In my case spouse was the secondary card member.(6 months)
5) Joint Bank statements (6 monts)
6) Other benefits (401K), investments where the spouse name is included or is a beneficiary
7) Medical insurance where spouse name is included
8) 1040 returns where I had filed married filing jointy.
