The spouses of H-1B visa holders—who hold H-4 visas—could lose their right to work in the United States under a Trump administration policy change in the works.

Silicon Valley news outlet The Mercury News reported Wednesday that senior leaders in the U.S. Department of Homeland Security have moved a step closer toward final approval of a policy change, part of Trump’s “Buy American and Hire American” executive order, that would stop at least some H-1B spouses from working in the country.
