President Donald Trump on Monday ordered the heads of the U.S. Department of Homeland Security and Department of Labor to “protect United States workers” from any damage to wages or working conditions caused by employment of foreign citizens on the H-1B visa. Trump’s executive order also directs chiefs of federal government agencies to audit their use of foreign contract workers.

Whether changes will be implemented and enforced remains to be seen, said Ron Hira, a Howard University professor who studies the H-1B. Major Silicon Valley technology companies may be affected, as most have extensive contracts with the federal government and also obtain workers from staffing and technology firms, Hira said. A 1976 federal law prohibits foreign citizens from holding jobs in the federal civil service, but many federal contractors employ large numbers of foreign workers.
