My wife filed petition I 130 for me back in 2006 and we were interviewed in early 2007. Our application was pending for longest time due to Name check and then I 130 and I 485 applications were denied because on suspicion of Sham marriage. Wife filed appeal with BIA which turned in our favor Recently USCIS local office sent me a letter for an I 485 interview and asked me to show up there with documentation. I am out for work for past couple of years because I don't have work permit and I am not able afford an attorney. Any body was in the same situation and was called for I 485 after I 130 interview. Do I need to take my wife as I don't want to do more than what they want?
