We do not have a visa for this person:
http://en.wikipedia.org/wiki/United_States_visas
As stated we have the H1-B, which is probably what he applied for, but it has special rules which are meant to prevent non-citizens from taking jobs from citizens.
We don't have an entrepreneur job classification - in other words he was rejected based on the idea that his job as CEO could easily be filled by a citizen.
I wonder if he managed things differently, working with an immigration lawyer, would he have been able to arrange his job description and company organization such that he would have been given a visa.
But we obviously need immigration reform. I still don't buy the argument that if we open the floodgates professionals and laborers both will be living on the streets. There are too many busybodies with their fingers in the pot.
But even with all that - we allow more immigrants into the US per year than all other countries combined, so it's not as though we're stingy. He simply wasn't one of the 85,000 people chosen for an H1-B visa this year.
