Hey Guys!
               I am also doing AOS through DV. I just recieved the notice of application of my I-485 and I-765. But I heard that we dont need to file I-864(Affidavit Of Support). Thats why I have not submitted I-864.The thing I submitted to chicago LOckbox were:- I-485, I-765, sealed I-693, copy of +2 transcript, unofficial transcript of current university,copy of visa, passport and I-94,copy of all I-20s and money order. Can anyone please help me in this case and point out what I am missing? If I am missing some application procedure, will USCIS notify me of that missing stuff?

Please share all yours experience.

Thanks in advance.
