九所名校被联邦调查：哈佛、耶鲁、斯坦福、MIT等涉J-1项目
美国政府10月8日表示，将调查九所大学使用J-1交流访问签证的情况。被点名的学校包括哈佛、耶鲁、斯坦福、布朗大学、匹兹堡大学、加州大学戴维斯分校、加州理工学院、亚利桑那州立大学和麻省理工学院。劳工部监察长安东尼·德埃斯波西托称，传票已经送达，调查将查看J-1项目是否合规，也会审查外国影响、财务关系和联邦科研资金使用情况。
政府官员称，这些学校在联邦资助科研项目中使用J-1研究人员比例偏高，可能影响美国研究生和研究人员的薪酬与机会。副总统万斯引用了约61%对比全国平均38%的数字，但相关计算方法尚未公开。这个区别很重要：联邦科学数据表明，在科学、工程和健康领域，临时签证持有人本就占博士后相当大比例，所以“比例高”本身不能直接推出学校违规。
哈佛、MIT、布朗和匹兹堡大学表示已收到传票并正在审阅；斯坦福、耶鲁、UC Davis和亚利桑那州立大学则强调合规或表示配合；加州理工在发稿时暂未见公开回应。需要强调的是，这一步是调查启动，不是法院或机构已经认定任何学校违法。
对在美华人学生、访问学者和博士后来说，眼下被调查的是学校项目管理，公开宣布中没有点名指控某个J-1个人违法。身在这九所学校的人，应以学校国际办公室通知为准，保存DS-2019、聘用和资助文件，不要把传闻当成个人身份结论。（GSM 据10月8日政府宣布及AP、USA Today、STAT等报道摘编）
Nine Universities Face Federal J-1 Investigation as Subpoenas Are Served
The administration said Oct. 8 it will investigate nine universities over their use of J-1 exchange-visitor visas. The schools named were Harvard, Yale, Stanford, Brown, the University of Pittsburgh, UC Davis, Caltech, Arizona State University and MIT. Labor Department Inspector General Anthony P. D'Esposito said subpoenas had been served and that investigators would examine J-1 compliance as well as foreign influence, financial relationships and use of federal research funds.
Administration officials argued that the schools rely heavily on J-1 researchers in federally funded work and could disadvantage U.S. graduate students and researchers. Vice President J.D. Vance cited figures of about 61% versus a 38% national average, but officials have not publicly explained how those figures were calculated. That matters: federal science data show temporary visa holders make up a large share of postdocs in science, engineering and health fields, so a high J-1 share alone does not prove a violation.
Harvard, MIT, Brown and Pitt said they had received subpoenas and were reviewing them. Stanford, Yale, UC Davis and Arizona State stressed compliance or cooperation; no public Caltech response was located at press time. This is the opening of an investigation, not a court or agency finding that any school broke the law.
For Chinese students, visiting scholars and postdocs, the immediate point is institutional: the probe targets university program management, and no announcement named individual J-1 holders as accused of wrongdoing. Readers connected to the nine schools should follow their international offices, keep DS-2019 and appointment/funding records, and rely on official notices rather than social-media rumor.
