美国内部政争失控，波及哈佛国际学生

Core Viewpoint - The attractiveness of American universities to both foreign and domestic talent is expected to decline sharply due to ongoing political turmoil, leading to a more pronounced trend of "de-Americanization" of global top talent [1][6]. Group 1: Government Actions - In June 2019, then-presidential candidate Trump expressed concern over the loss of talent from prestigious universities like Harvard and proposed measures to retain foreign graduates by offering green cards [1]. - A year later, Trump signed two executive orders affecting foreign students, including travel bans for 12 countries and visa restrictions for 7 countries, signaling a strong stance against foreign student admissions [1]. - The Department of Homeland Security intensified background checks on foreign students, resulting in over 1,000 students facing visa revocations or loss of legal status from March to April 2020 [2]. Group 2: Harvard University Conflict - The conflict between the Trump administration and Harvard escalated, with the government freezing federal funding to universities for review, although courts later overturned this action [4]. - Harvard became a primary target for the Trump administration, which threatened to review $9 billion in federal funding and imposed demands to reform its policies, leading to a freeze of $2.2 billion in federal aid [4]. - The administration attempted to leverage the cancellation of Harvard's long-standing certification for international student programs to pressure the university, but Harvard successfully challenged these actions in court [4]. Group 3: Impact on International Students - As of the fall 2023 semester, international students made up over 27% of Harvard's total enrollment, with nearly 6,800 students from over 140 countries [5]. - The U.S. Secretary of State issued orders to halt new student and exchange visa interviews, indicating the government's willingness to bypass judicial protections to limit international student admissions [5]. - Despite recent reports of the State Department resuming visa processing for Harvard's foreign students, the overall situation remains uncertain, contributing to a decline in the attractiveness of U.S. universities [6].
