Hi guys! It's been over two years since me and my wife (American citizen) went to out first interview. Our case has been pending since then. Recently, I called Immigration and got transferred to some nice lady who said that she would send a request on my behalf to our local office so that they would send me an update regarding my family-based petition. Couple days ago we received a receipt notice with my wife's (not mine) name on it asking us to show up for the interview "for the completion of her Petition for Alien Relative (Form I-130) and any supporting documentations or petitions". Can anybody explain to me a little bit more detailed what it means and what's the difference between I-130 and I-485 interviews. I will greatly appreciate any answer. Thanks.
