Congratulations!
You are lucky enough to get both your I-140 and I-485 approval straightly. Yesterday, 153 got his I-140 approval but his I-485 is required for an interview.
Mine is also NIW based, with RD on 5/5/2003. Yesterday, I just got a notice for my FP, which is scheduled on A Election Day (11/2). I noticed that you had a RFE for your I-140 this June. Could you tell me more details on your RFE? Thanks in advance!
