The Trump administration's new rule limiting how long international students can remain in the United States could reduce economic output by as much as $400 billion annually, weaken the country's innovation pipeline and discourage foreign students from choosing US universities, according to a report by the Peterson Institute for International Economics (PIIE).
The rule, issued in July and set to take effect in September, replaces the long-standing "duration of status" policy with a fixed period of stay of up to four years for most international students. After that, students would need to apply for an extension to continue their studies or remain in the country for post-graduation work.
