Core Viewpoint - The article discusses the implications of the Trump administration's policies on international students, particularly Chinese students, amid escalating US-China trade tensions and the potential impact of changes to the "D/S" (Duration of Status) residency permit for student visa holders [1][10]. Summary by Sections D/S Residency Permit and Its Significance - The "D/S" residency permit allows international students to remain in the US as long as they maintain their student status, which is separate from the validity of their visa [5][11]. - The Trump administration's recent proposal to eliminate the "D/S" status could significantly affect the ability of international students to stay in the US, particularly impacting F visa holders [10][19]. Historical Context of D/S Permit - The concept of "D/S" has evolved from early US immigration laws, which initially did not require formal registration for foreign nationals [3][7]. - Historical examples, such as Qian Xuesen, illustrate the complexities and bureaucratic challenges faced by international students in maintaining their legal status in the US [7][9]. Abuse of D/S Permit and Consequences of Trump's Policies - The article highlights that the D/S permit has been subject to abuse, allowing some students to remain in the US indefinitely by continuously enrolling in academic programs [11][12]. - The potential elimination of D/S could lead to a decline in international student enrollment, negatively impacting the financial health of US educational institutions [19][21]. Broader Implications for US Education and Research - The proposed changes to the D/S permit are seen as detrimental to the US education system, particularly for graduate programs that rely on international students [21][22]. - The article argues that the new policies could undermine the quality of doctoral education in the US, as students may face increased pressure to graduate within a limited timeframe [21][22]. National Security and Geopolitical Considerations - The article discusses the broader geopolitical implications of the Trump administration's policies, including the targeting of Chinese universities and students as part of a national security strategy [23][31]. - The inclusion of Chinese universities in a list of institutions deemed sensitive reflects a growing trend of restricting academic exchanges and collaborations between the US and China [23][31].
