That's why employers such as Google and Microsoft, which say they're short of highly trained software engineers, have lobbied hard to expand the program beyond the 65,000 visas available annually. These high-tech companies say they can't meet their needs from the pool of U.S. graduates in STEM specialties — science, technology, engineering and math.
