Commentary: The United States has historically been the most attractive destination for foreign researchers, with the highest levels of R&D investment and many of the world's best hospitals, universities, and research institutions. However, recent changes and upheavals in U.S. science funding and immigration policy have led many prospective foreign researchers to look elsewhere for positions, while many foreign researchers currently based in the United States have left to pursue other opportunities abroad. In a survey of 1,000 U.S. researchers supported by the National Institutes of Health (NIH), 13 percent said that their labs had lost researchers to other countries as a result of NIH funding changes, while 14 percent reported that immigration policies forced scientists, students, and postdocs to turn down offers to work in NIH-supported labs. Moreover, labs have reported receiving fewer applications from international students and researchers, reflecting uncertainty and confusion surrounding the current immigration and research policy environment in the United States.
