Purdue University denied an official ban on Chinese students after reports that dozens of offers had been rescinded following warnings from legislators; students and faculty, however, said an informal policy is sidelining applicants from China and other nations. Purdue officials told reporters there is no formal ban but acknowledged recent admissions disruptions. The episode follows wider pressure on U.S. campuses to curtail partnerships with Chinese institutions amid national‑security concerns. Universities are balancing compliance with federal scrutiny, congressional inquiries, and recruitment declines from key international markets; affected departments say the uncertainty is disrupting graduate programs and research pipelines.
