"It took only 10 weeks this year to reach the FY2013 visa cap of 85,000. Last year, it took more than three times longer, 33 weeks. "
SO employers are 'racing' to get the H1-B applicants in, and due to the ridiculous quota, the race is over in a little over two months. So anybody hoping to get a H1-B visa, who is not employed at a really lawyered company will have trouble staying in the country.
Silicon Valley basically would not be what it is today if it were dependent solely (or even largely) on labor performed by American citizens.
