I also got RFE from NSC. My immigrant officer is EX375. What immigrant officer reviews your cases?
I heard EX375 and EX206 are the most toughest. If you got from other officers, generally you don't need too much worry. Just try you best to get more independent letter and update your papers and citations. Mostly, you will get approved within two weeks after summiting your RFE.

But I am unlucky. I am very frustrated and worried.
