walterbyrd sends this excerpt from the LA Times: "In a rare show of unity, Facebook Chief Executive Mark Zuckerberg and Yahoo Chief Executive Marissa Mayer were among a coalition of high-profile executives and venture capitalists to send a letter on Thursday to President Obama and congressional leaders pressing for a fix to restrictive immigration laws by year's end. Silicon Valley entrepreneurs, investors and executives are also planning a virtual "march" on Washington in April. 'Because our current immigration system is outdated and inefficient, many high-skilled immigrants who want to stay in America are forced to leave because they are unable to obtain permanent visas,' the letter says. 'Some do not bother to come in the first place.'" The letter also offers these suggestions: "We believe that numerical levels and categories for high-skilled nonimmigrant and immigrant visas should be responsive to market needs and, where appropriate, include mechanisms to fluctuate based on objective standards. In addition, spouses and children should not be counted against the cap of high-skilled immigrant visas. There should not be a marriage or family penalty."
