The US Immigration and Customs Enforcement (ICE) is now tracking nearly 54,000 immigrants through GPS-enabled ankle monitors, a sharp rise from just 17,000 early last year. This surge in ankle monitor tracking reflects a major policy shift within ICE's electronic surveillance program, raising significant privacy and legal concerns.
Why ICE Ankle Monitor Numbers Tripled
According to private prison corporation The Geo Group, which runs ICE's Intensive Supervision Appearance Program (ISAP), the overall enrolled population stayed flat at about 184,000. However, a June 2025 ICE memo directed agents to move more immigrants from lower-cost surveillance like phone check-ins to ankle monitors. This ankle monitor policy shift has driven the dramatic increase in GPS tracking.

The Geo Group's CEO, George Zoley, confirmed on an earnings call that this technology mix shift increases revenues even with stable participation. Ankle monitors cost ICE just over $2 per day per person, while the SmartLink facial recognition app costs only $0.96 per enrollee. More than 127,000 immigrants currently use SmartLink, but the trend is clearly toward more intensive monitoring.
Financial Impact and Private Prison Profits
The financial implications are significant. The Geo Group, which owns BI Inc, directly benefits from this shift. As more immigrants are placed on ankle monitors, the company's revenue from the ISAP contract grows. This has led to criticism that the policy prioritizes corporate profits over individualized assessment.
Here's a cost comparison table based on publicly available ICE statistics:
| Surveillance Method | Daily Cost per Person | Number Enrolled |
|---|---|---|
| Ankle Monitor (GPS) | $2.00+ | ~54,000 |
| SmartLink App | $0.96 | ~127,000 |
| Phone Check-in (other) | Varies | Remaining ISAP |
This table highlights the financial incentive behind the policy. The Geo Group revenue growth is directly tied to the number of ankle monitors deployed, creating a potential conflict of interest.
Legal Challenges and Privacy Concerns
A new class-action lawsuit filed against ICE in June alleges that this "ankle monitors for all" policy imposes continuous, real-time GPS monitoring without individualized justifications. Immigration advocacy groups argue that the mass shift violates due process and privacy rights.
The lawsuit contends that many immigrants are subjected to constant surveillance without any evidence of flight risk or danger. This legal challenge could reshape how ICE uses electronic monitoring in the future, potentially forcing a return to more proportionate surveillance methods.
Key Takeaways from the ICE Ankle Monitor Data
- Ankle monitor usage tripled from 17,000 to nearly 54,000 in about 18 months.
- The policy shift was directed by an ICE memo in June 2025.
- Geo Group profits rise as more immigrants are placed on monitors.
- Legal challenges argue the policy is unconstitutional and overly broad.
- SmartLink remains the cheaper, less invasive alternative for many.
For immigrants and their families, this means increased scrutiny and potential financial burdens, as some may be required to pay for the devices. The long-term consequences of this surveillance expansion are still unfolding, with court battles likely to determine its legality.
As the situation evolves, staying informed about ICE policies is crucial. Whether you are directly affected or simply monitoring immigration news, understanding the data behind ankle monitor tracking helps clarify the real-world impact of these enforcement decisions.
