Question:

Why might an EB-5 application be returned from the NVC to USCIS? In Dec. 2012, I applied for my I-526, which was approved after I left the United States (because the OPT I was on expired). I started the DS-260 application after my I-824 got approved. I am back in the United States with a B-1 visa right now. However, I just received notice that my EB-5 case was returned from NVC to USCIS without any reason. Could the B-1 visa be causing a problem? What usually causes an EB-5 application to be returned from the NVC to USCIS?
