3/12/2008-US high-tech companies are being forced to outsource more jobs overseas because of outdated restrictions on immigration, Microsoft chairman Bill Gates told Congress Wednesday. Gates, echoing a longstanding complaint from the technology sector, told a congressional panel that the US immigration system "makes attracting and retaining high-skilled immigrants exceptionally challenging for More..

He said the current cap of 65,000 H-1B visas "is arbitrarily set and bears no relation to the US economy's demand for skilled professionals." The Microsoft founder noted that all the 65,000 visas for the current fiscal year were snapped up in one day last April and that employers are now waiting to apply for visas for fiscal 2009, starting in October.

For instance, Microsoft has found that for every H-1B hire we make, we add on average four additional employees to support them in various capacities." Gates also said the United States needs to improve science and math education to train a new generation of...
