Thanks, EB10182006.
madgu-gc2005, I posted my qualification and RFE before. Basically, in the response to the RFE, I only focused on 4 points that I think would be easy for me to be qualified, including publications, news, impact and referee. I gave up trying to convince NSC about the "national award", "membership" and "leading role". My impression is that there would have been a chance to get later 3 points approved if my case was at TSC, but there is NO chance at NSC. So I decided not to waste my time nor the USICS officer's time. This seems worked for me, but everyone's case is different. Hope both you and EB10182006 get approvals soon. Although NSC is tough, there still is a hope.
Good luck.
