美国总统特朗普政府已对哈佛大学、耶鲁大学、斯坦福大学等九所领先的美国大学展开调查，原因是这些大学被指控滥用J-1交流访问签证，以低于美国工人的工资雇佣外国研究人员。副总统JD·万斯周四宣布了这一消息。
The administration of US President Donald Trump has launched an investigation into nine leading US universities, including Harvard, Yale, and Stanford, over allegations that they improperly used J-1 exchange visitor visas to employ foreign researchers at lower wages than American workers, Vice President JD Vance announced Thursday.
该调查于10月8日披露，由劳动部监察长办公室进行，该办公室已发出传票，要求提供有关签证做法、外国资助以及大学研究中可能存在的外国影响的信息。
The investigation, disclosed October 8, is being conducted by the Labor Department's Office of Inspector General, which has issued subpoenas seeking information about visa practices, foreign funding, and possible foreign influence in university research.
接受审查的机构包括哈佛大学、耶鲁大学、斯坦福大学、布朗大学、亚利桑那州立大学、匹兹堡大学、麻省理工学院、加州理工学院以及加州大学戴维斯分校。万斯指责这些大学在联邦资助的项目中过度依赖外国研究人员。
The institutions under scrutiny are Harvard, Yale, Stanford, Brown, Arizona State University, the University of Pittsburgh, the Massachusetts Institute of Technology, the California Institute of Technology, and the University of California, Davis. Vance accused the universities of relying excessively on foreign researchers for projects supported by federal grants.“Something weird is going on at these universities,” Vance said.
“这些大学里发生了一些奇怪的事情，”万斯说。“他们过度使用这些签证。他们利用这些签证来压低美国研究生和美国研究人员的工资，这必须停止。”
“They're using these visas way too much. They're using them to undercut the wages of American grad students and American researchers, and it simply has to stop.”
根据万斯的说法，在这九所院校中，持有J-1签证的研究人员约占联邦资助项目研究人员的61%，而全国平均水平为38%。
According to Vance, J-1 visa holders account for approximately 61% of researchers working on federally funded projects at the nine institutions, compared with a national average of 38%.
他没有解释这些数字背后的方法论。J-1 项目允许外国公民临时进入美国进行学术交流、研究、教学和专业培训。哈佛正在审查传票，发言人确认哈佛发言人杰森·牛顿确认该大学已收到传票并正在审查，哈佛《克里姆森报》报道。尚未宣布任何欺诈调查结果。哈佛此前曾在2025年7月因参与交流访问者项目而接受美国国务院调查，同时其国际学生政策也受到联邦层面的审查。
He did not explain the methodology behind those figures. The J-1 program permits foreign nationals to enter the United States temporarily for academic exchanges, research, teaching, and professional training. Harvard reviewing subpoena, spokesperson confirmsHarvard spokesperson Jason Newton confirmed that the university had received a subpoena and was reviewing it, The Harvard Crimson reported. No findings of fraud have been announced. Harvard previously faced a State Department investigation into its participation in the exchange visitor program in July 2025, alongside federal scrutiny of its international student policies.
此次调查是更广泛的政府行动的一部分，旨在打击基于就业的移民。周四，官员们还宣布对多家科技公司实施限制，包括微软，限制其为外籍工人担保永久居留的能力。
The latest investigation forms part of a wider administration campaign targeting employment-based immigration. On Thursday, officials also announced restrictions on several technology companies, including Microsoft, concerning their ability to sponsor foreign workers for permanent residency.
