Quick glance and please correct me if I got this wrong:
This only affects immigrants with permanent residency status who have been sponsored through this bill/law. You stated:
"This is a bill that proposes to give US venture capitalists the overt ability to terminate the residency status of founders and their families."
True in the sense that if the sponsored entrepreneur was unable to fulfill the job creation, capital investment, and revenue generation terms, then they technically were unable to create a successful enterprise. Any foreign 'entrepreneur' worth his salt should and must know of this requirement and in the awareness of it, must have prepared himself and his family for the consequences.
As for part (A) "...the qualified venture capitalist or qualified super angel investor who sponsored the entrepreneur failed to meet the investment requirements..."
I think this refers to the initial requirements that needed to have been met before the foreign entrepreneur is approved for residency. It could be that the VC committed to the investment (That IS a bitambiguous, but from experience, immigration officials will approve an application and give you a chance to fulfill a financial commitment some time after the sponsored entrepreneur has arrived, provided they are satisfied with whatever guarantee docs you've filed with them.) but was unable to fulfill it, so Homeland Security will start the process of terminating the permanent residency status of the sponsored entrepreneur.
Can this be twisted around by an 'evil' VC? I believe any system CAN be abused around given enough motivation. In this case, if I were an evil VC who convinced Mr. Chatroulette founder from Russia to come to America to blow his idea up 1000x through me, I'd bring him in, dupe him into signing his life away in a 'partnership', promise Homeland Security that I will fulfill my financial commitments, squeeze everything I can from this naive new sponsored entrepreneur in the 6mos-1yr that Homeland Security will take to enforce my commitment, then not pay up. Back to Russia goes 'sponsored entrepreneur' and his concept/resources stay here in the US.
Bottom line for all parties, due diligence. I believe the bill is being put forward in good faith. I believe that they believe it can create jobs. I believe that it is possible it can.
But all things considered, I'd rather concentrate resources on finding the cream of the crop in the US and helping THEM.
