Dozens of U.S. business leaders, including CEOs at top American companies, recently signed a joint letter to Homeland Security Secretary Kirstjen Nielsen. They expressed "serious concern" over several Trump administration immigration policies, focusing on those surrounding H-1B visas. The signatories of the joint letter included the heads of Apple, IBM, Salesforce, BlackRock, PepsiCo, JPMorgan Chase and others.
Although the Trump administration has stated a preference for employment-based rather than family-based immigration, it appears to be taking steps to limit some employment- and investment-based immigration programs. This includes additional scrutiny of H-1B applications and the virtual elimination of several other programs for skilled immigrants.
The H-1B visa allows certain highly skilled people to work in the U.S. for several years. It also allows fashion models and specific workers on Department of Defense projects to work temporarily in the United States. What H-1B visas are most noted for, however, is bringing in foreign talent when high-tech industries can't fill their jobs with home-grown workers.
