ICE ankle monitor tracking has surged to nearly 54,000 immigrants, a dramatic increase from just 17,000 early last year, according to private prison corporation The Geo Group. This expansion reflects a broader shift toward high-security electronic surveillance in U.S. immigration enforcement, with significant financial implications for contractors and legal challenges from advocacy groups.
Why ICE ankle monitor numbers tripled
The Geo Group, which owns BI Inc and runs ICE’s Intensive Supervision Appearance Program (ISAP), reported the jump in its earnings call on Thursday. While overall ISAP enrollment remained flat at about 184,000, the mix shifted heavily toward ankle monitors. In June 2025, ICE directed agents to move more participants to ankle monitors, according to a memo obtained by the Washington Post.

This policy, dubbed “ankle monitors for all” by critics, imposes continuous real-time GPS tracking without individualized justifications. The shift has been financially lucrative: ankle monitors cost ICE more than $2 per day per monitor, compared to $0.96 for the SmartLink app, which uses facial recognition and location tracking.
Financial impact on Geo Group
Geo Group CEO George Zoley confirmed on the earnings call that the technology mix shift will "continue to increase revenues and earnings generated under the ISAP contract even if overall participation counts remain relatively stable." With over 127,000 immigrants still using SmartLink, the potential for further conversion to ankle monitors represents a major revenue driver.
However, this growth comes amid legal scrutiny. A new class-action lawsuit filed against ICE in June alleges the ankle monitor policy violates due process and privacy rights. Advocacy groups argue that mass GPS surveillance is disproportionate and stigmatizing.
Comparison of ICE surveillance technologies
| Technology | Daily Cost per Person | Number Enrolled | Surveillance Level |
|---|---|---|---|
| Ankle Monitor | $2.00+ | ~54,000 | High (real-time GPS) |
| SmartLink App | $0.96 | ~127,000 | Medium (facial recognition & location) |
| Phone Check-in | Minimal | Remaining ISAP | Low |
Key takeaways from the ICE ankle monitor expansion
- Ankle monitor usage tripled from 17,000 to 54,000 in about 18 months.
- ICE’s June 2025 memo directed agents to prioritize ankle monitors over less intensive options.
- Geo Group profits rise as more immigrants are placed on higher-cost monitoring.
- Legal challenges argue the policy lacks individualized justification and violates rights.
- SmartLink remains the most common surveillance method, but conversion could accelerate.
What this means for immigration policy
The rapid growth in ankle monitor tracking signals a tougher enforcement stance under current ICE leadership. Supporters argue that GPS monitoring ensures court appearance compliance and reduces detention costs. Critics counter that it creates a two-tier system where non-citizens are subjected to constant surveillance without equivalent legal protections.
For immigrants enrolled in ISAP, the shift means less freedom and greater privacy invasion. For taxpayers, the higher per-person cost of ankle monitors may increase overall spending even if total enrollment stays flat. The outcome of the class-action lawsuit could reshape how ICE uses electronic monitoring in the future.
