I just received my appointment letter in the mail. It will be in a month so I am getting everything ready as soon as possible. With my application I submitted the affidavit of support with all the required documentation. I had to use a co-sponsor because my wife did not meet the requirements. On the interview letter asks me to bring tax returns and W-2s (unless submitted before). The tax returns I have are from the time I filed (1 year ago), so they are from 2004,2003,2002. Do I have to show my co-sponsor's latest tax returns at the interview or just bring copies of the ones filed with my application. Also, do they ask about employer's letters or are pay check stubs enough?
