美国开始取消部分中国留学生签证

Core Viewpoint - The U.S. State Department has begun canceling visas for certain Chinese students, particularly those linked to the Chinese Communist Party or involved in significant research areas, as part of efforts to prevent high-end technology from flowing to China, which is seen as a competitor in military, economic, and technological fields [1][2]. Group 1 - The U.S. State Department is collaborating with the Department of Homeland Security to enhance scrutiny of all visa applications from mainland China and Hong Kong, indicating a shift in review standards [2]. - The trend of "U.S.-China decoupling" is increasingly affecting the academic sector, reflecting heightened tensions in the high-tech domain [2]. - The number of Chinese students in the U.S. peaked at 370,000 in the 2020 academic year but has since declined, with an estimated 280,000 expected for the 2024 academic year, representing about 25% of the total international student population in the U.S. [2]. Group 2 - The Trump administration previously restricted visa issuance to Chinese students under the pretext of technology leakage, and this trend appears to be continuing under the current administration [2]. - Harvard University was notified by the government to suspend its eligibility to accept international students, with accusations of fostering violence and anti-Semitism on campus [2][3]. - Universities in the U.S. must obtain certification from the Student and Exchange Visitor Program (SEVP) to enroll international students, and losing this certification would prevent them from issuing necessary visa application documents [3].
