Talk to the founders of Silicon Valley startups and they will tell you that the single greatest obstacle they face after they obtain funding is the dearth of skilled talent. They say this is limiting their ability to innovate. A group of tech CEOs told President Obama in March that five companies alone — IBM, Intel, Microsoft, Oracle, and Qualcomm — had 10,000 job openings in the US. They called this “one of the biggest economic challenges facing our nation” and asked the president to address the need for more qualified, highly-skilled professionals, domestic and foreign, and to urgently enact immigration reform.
