Thank again for your advice for the duplicated NC requirment ealier. (I don't know why these post disappeared.) My another question is the meaning of "under review" about my I-485 (NIW)case. Does it indicate that my case will be keep processing,like sending the RFE (if any) even before my PD become current? Or it will be only continued after the cut-off date ealier than my PD?
