A House Select Committee inquiry into Purdue University alleges the institution has implemented an unwritten policy rejecting graduate applicants from China and other countries designated as 'adversary nations.' The probe claims the university was investigated over its handling of Chinese students and implies admissions decisions may be tied to national‑security concerns. Purdue faces scrutiny from lawmakers and commentators who argue universities must balance research security and foreign‑student access; university officials have defended admissions processes while federal committees explore whether undue exclusion is occurring. The matter highlights tensions between compliance with national security directives and universities’ traditional international recruiting missions.
