Visa time limits on foreign PhD students and postdocs will harm U.S. science
a day ago
- The Trump administration plans to replace the decades-old 'duration of status' policy, limiting international students and postdocs to four years on nonimmigrant visas unless they apply for extensions.
- The Department of Homeland Security cites the need to prevent 'forever students' from manipulating the system, claiming it identified over 2,100 students who remained in the U.S. for 15+ years.
- Critics, including immigration experts and university officials, warn the rule will deter top foreign talent, harming U.S. scientific competitiveness, especially in biomedical fields where 59% of postdocs are international.
- The average biomedical PhD takes 5–6 years, and about 20% of postdocs work for over six years, meaning most would need DHS extensions, creating potential backlogs and administrative burdens.
- A NAFSA survey found nearly half of international students and postdocs would not have come to the U.S. under a fixed admission period, and 67% prefer duration-of-status policies.
- The University of California system estimates one campus alone would need to process over 4,500 extension applications annually, warning of delays and deterrence.
- Even before the rule, international graduate student enrollment dropped 12% in fall 2024 due to concerns about funding, visa fees, and travel bans.
- White House policy chief Michael Kratsios argued the U.S. is overly dependent on foreign talent, sidelining American students, while critics like Penn State's Andrew Read fear the move jeopardizes international collaboration.
- The rule takes effect September 15, though current students finishing before September 2030 are exempt from extensions.
