How about just giving them a visa if they can secure VC funding in the United States enough to support them in their efforts for a year or two. Also reforming the h1b visa might help, since most immigrants are highly motivated to start their own businesses ... allowing h1bs more easily start businesses (currently you have to have someone, an American citizen, have some sort of controlling interest in your business for it to be a viable means of employment), have time after losing a job to find another one (currently you have to leave immediately after you're fired/laid off).
