The EB-5 program is most famously opposed by Sen. Dianne Feinstein (D-CA), where she says it allows wealthy foreign nationals to buy their way through the legal immigration process and eventually to gaining U.S. citizenship.
Very seldom, if ever, do I agree with Sen. Feinstein. However, this is one time I fall solidly on her side. American citizenship should not be sold and bought like a cheap commodity!
