I sent my stand alone I-485 on 03/14/2011 to Chicago its two weeks already and I have not received email notification stating that the case was received or anything. Now granted that my I-130 was approved last year 06/28/09 and the NVC was holding it until the Priority date became current. My wife later became a citizen and we upgraded that petition with NVC and USCIS to immediate relative. Is this really unusual or does anybody know??????????????????????????????????? I'm really getting impatient
