These are not directly from USCIS or DOS, but they cite DOS as the source of the figures.
I found them through this EB5 blog.
They can be found here.
There does not seem to have been much usage in Q2.
On January 23, 2012 a USCIS document estimated 2,364 had been used as of January 17, 2012.
This document has a figure of 2,405 at the end of February.
Perhaps that explains where some of the QSP was coming from.
Again, it confirms that EB5 usage in FY2011 was 3,463 vs. 1,885 in FY2010.
