Help me understand this? Is there a shortage of startups in the USA? Can startups (that in reality have an online-only product) not occur outside the USA? These are honest questions, I'm trying not to be biased, why come here?
People who go into America on this visa won't be a burden on American tax payers, and if they fail to succeed then their visa will expire. If, on the other hand, they succeed, whether in making a profitable five-person company, or in creating the next Facebook-sized success, then their being in America is a good thing for the country's economy.
Basically it's a no-lose possible-win situation.
