My parents came to the United States on a temporary visit but stayed, drawn by the promise of opportunity. That same belief brings international students here today. As head of education for the American Physical Society, the nation’s largest physics organization, I understand the deeply personal decision of coming to the U.S. and choosing to stay — just like my family.
These students, along with their American counterparts, are vital to the U.S. science, technology, engineering and math workforce. Their research at universities drives innovation, launches businesses and creates high-quality jobs. Yet their future is threatened by proposed changes to F and J student visas.
The new rules would require students to complete their degrees within four years, with the opportunity for an extension that is not guaranteed. Earning a PhD in physics is a demanding process that should not be rushed. It takes an average of at least six years, and hurrying the process would create unnecessary anxiety among students, leading them to take even longer to finish their degrees.
The American Physical Society is offering resources and recommendations to help students prepare for what lies ahead, including advising them to postpone unnecessary travel until the rules are finalized. Losing their talent would harm our nation’s long-term scientific and economic strength.
We must not allow policy changes to harm opportunities that have long sustained America’s leadership in science and innovation.
