May 1, 2018 – “Scientific progress depends on openness, transparency and the free flow of ideas; these principles have helped the United States to attract and benefit from international scientific talent. Students and scientists from other countries strengthen U.S. innovation. We are concerned about news reports that the U.S. administration is considering further restrictions on visas that could limit the travel of Chinese students and scholars from China to the United States. To remain the world leader in advancing scientific knowledge and innovation while ensuring national security, the U.S. science and technology enterprise must continue to capitalize on the international and multicultural environment within which it operates. We strongly recommend that the administration work with the scientific community to assess and develop potential policy actions that advance our nation’s prosperity. Where specific and confirmed espionage is occurring, action must be taken, but obstructing scientific exchange based on non-specific concerns that could be applied to broad swaths of people is ill-conceived and damaging to American interests.”
