Foreign nationals propel U.S. science. Visa limits under Trump could change that

Foreign nationals play a crucial role in U.S. science, comprising about half of the doctoral-level scientists and engineers in the country. Many of these professionals are employed under H-1B visas, which allow up to 85,000 skilled workers to work in the U.S. for up to six years. However, the incoming Trump administration is expected to impose stricter regulations on H-1B visas, potentially hindering universities, research institutions, and tech companies from accessing the talent they need. This situation could mirror the impact of Brexit in the U.K., where restrictions led to a loss of skilled scientists. Concerns are rising among international students and researchers, such as Leili Mortazavi, who fear that renewed visa limitations could force them to seek opportunities abroad. During Trump's first term, several institutions challenged visa restrictions in court, but currently, many universities are refraining from public comments on the anticipated changes. The Trump transition team has not provided details regarding future H-1B visa policies.
