entrepreneurs are no stranger to risk. yes, there is a risk they do not meet the basic qualification to remain in the country. however, they are fairly basic: can you create a minimum of 5 jobs in the US within 2 years? (or reach break-even on $1M in revenue, or raise subsequent financing of $1M or more).
entrepreneurs who fail to meet the bar are not being unfairly punished by investors, rich or otherwise.
these rqmts are simply the proposed bar for qualification. meet them, and you can stay. nothing more, nothing less.
this is a considerably better situation than what we have currently.
