XDJM,
It seems NSC is processing NIW now. I just got an email for approving the I-485 for both of my hu*****and and me.
My case is:
NIW (DIY) sent to NSC in 09/05
I-140 approved in 10/05
1st FP 12/05
2nd FP 04/07
06/05/07 checking with Inforpass, NC is pending
I-485 approved on 06/18/07 without any LUD.
Good Luck to you all. Thank you for all help you'v provided.
