The U.S. Department of Homeland Security has extended the time some foreign graduates of U.S. colleges can stay in the country and work, earning the agency praise from Microsoft and other supporters of increased numbers of foreign worker visas.

DHS extended from 12 months to 29 months the length of time a graduating student in science and technology fields can stay in the U.S. without a worker visa. Microsoft and other supporters of a higher cap on H-1B immigrant worker visas have complained the quota fills up before students graduate each year, and the 12-month period didn't give those student enough time to become part of the next year's H-1B crop.

The yearly cap on H-1B visas is 65,000, not including an additional 20,000 visa for graduate students at U.S. universities. In recent years, the cap has been filled within days or hours of applications being available.

Microsoft on Monday praised the DHS decision to extend the Optional Practical Training (OPT) program, announced last Friday. The decision is "an important step toward ensuring that American companies can continue to hire many of the world's most talented students graduating from U.S. universities," Jack Krumholtz, Microsoft's managing director federal government affairs, said in a statement.

The extension of the OPT program allows U.S. companies to recruit and retain the "best" science and tech students educated at the top U.S. universities, Microsoft added. "In the past, these students were often unable to remain in the United States for more than a year after completing their degrees because they could not obtain the necessary work visa in spite of being offered gainful employment in highly innovative companies due to the extreme shortage of H-1B visas," Krumholtz added.

The new DHS rule comes as the result of a congressional "failure" to pass immigration law reform, said Richard Herman, of Richard T. Herman & Associates, a Cleveland, Ohio, law firm focused on immigration law.

The extension is "a stop-gap measure, and only highlights Congressional impotence on leveraging high-skill immigration for America's economic security," Herman said. "Congress cannot continue to hamper U.S. technology innovation and competitiveness by imposing nonsensical laws that turn away the world's best and brightest."
