trackitt has a very interesting thread about officer numbers for RFEs. Here is the NIW/EB1A/B portion of it:
EB1A
vayu: NSC - EB1A - EX202 - Dec 29, 2007 - ???
tacky100: NSC - EB1A - EX206 - Jan11,2008
EB1B
enduring: NSC - EB1B - EX102 - Jan 31, 2008 - ???
cplus: NSC - EB1B - EX206 - Feb 4, 2008 - ???
milliecent: NSC - EB1B - EX206 - Feb 12, 2008 - ???
EB2NIW
wwff: NSC - EB2NIW - EX375 - Jan 8, 2008 - ???
IntWaiv: NSC - EB2NIW - EX206 - Feb 1, 2008 - ???
gvhd: NSC - EB2NIW - EX375 - Feb 26, 2008 - ???
I think this answers JerIst's long standing question regarding the "outstanding" requirement for EB2NIW. It seems the same IOs process EB1A/B and EB2NIW cases. No wonder they get confused with the legal requirements. EX206 seems to be a trigger-happy RFE issuer who does all 3 categories, for example.
