None so far as I know, but I recall the Kushner thing being referred to in one of these EB-5 threads, which is how I learned about it. Without checking, I was guessing it was this one.
Sure. Kushner and company are using EB-5 to get lower interest loans/investments and to save a buck. The issue is that these projects are in areas that are not at all poor. As to Quiros, his motive for EB-5 was to, well, get money to use for however he wanted. Both demonstrate how EB-5 is in need of reform. As to that, I have two words: good luck.
