美国移民及海关执法局(ICE)通过GPS脚踝监听器追踪的移民数量急剧增长。[1]ICE目前通过脚踝监听器监控近54000名移民，相比去年初的17000名大幅增加。[1]这一扩张是由ICE在2025年6月发出的指示推动的，要求代理将更多参与者从成本较低的监控方式转向脚踝监听器计划。[1]
运营移民集中监督计划(ISAP)的私监狱公司Geo集团旗下BI Inc正是这一转变的主要受益者。[1]脚踝监听器的成本约为每人每天2美元多一点，相比之下使用SmartLink应用进行核实的成本约为0.96美元。[1]Geo集团主席兼首席执行官George Zoley表示该政策将增加公司的收入和收益。[1]为支撑这一扩张，Geo集团在2025年初投资了1600万美元用于脚踝监听器生产。[1]
移民倡导组织对这一政策提出了法律质疑。[1]移民权益组织Amica Center指控ICE的政策"没有个人化理由即实施连续的实时GPS监控"。[1]倡导组织已在6月对ICE提起集体诉讼，指控其监控政策存在违法行为。[1]与此同时，特朗普政府最近撤销了海地人的临时保护身份，可能导致数十万人面临拘留或驱逐，这可能进一步增加被监控移民的数量。[1]
U.S. Immigration and Customs Enforcement (ICE) is now tracking nearly 54,000 immigrants through GPS ankle monitors, a dramatic increase from approximately 17,000 tracked one year earlier [1]. The expansion represents a significant shift in monitoring methodology within ICE's Intensive Supervision Appearance Program (ISAP), which maintains a total participant base of approximately 184,000 people [1].
The migration toward more costly ankle monitoring reflects financial incentives embedded in the surveillance system. Ankle monitors cost more than $2 per person daily, compared to approximately $0.96 per day for the SmartLink application used by over 127,000 immigrants for check-ins [1]. In June 2025, ICE directed contractors to transition more ISAP participants from lower-intensity monitoring methods to ankle monitor tracking [1]. The Geo Group, a private prison company that operates BI Inc, which runs ISAP, invested $16 million in ankle monitor production in early 2025 [1]. Geo Group Chairman and CEO George Zoley stated that the policy expansion would increase revenue and profits [1].
The escalation has prompted legal action from immigrant advocacy organizations. Amica Center has accused ICE of implementing continuous real-time GPS monitoring without individualized justification, filing a class-action lawsuit against the agency in June [1]. Critics argue the policy amounts to mass surveillance of immigrants. The Trump administration's recent decision to terminate Temporary Protected Status for Haitians threatens to intensify pressure on the immigration detention system, potentially exposing hundreds of thousands of people to detention or deportation [1].
