I also got RFE from VSC
I also got RFE for my NIW(DIY) from VSC. After your submitting your response for RFE, didn't you have LUD for your case online? I got two times LUD, but there is no status change happen yet.
Good Luck, by the way, what the number of your Visa Officer ( on the right bottom part of the last page of the blue color RFE letter).
