Ban the use of solitary confinement in ICE detention.

Why it matters

While the use of solitary confinement in any carceral setting is detestable, its existence in immigration detention is especially egregious. Immigration detention is explicitly non-punitive, and yet a penal practice is used extensively and capriciously against thousands of detainees each year. In fact, over 10,000 people in ICE detention were subjected to solitary confinement between May 2024 and April 2025 alone. Detainees are frequently placed in solitary confinement cells for arbitrary infractions or in retaliation for protesting, reporting abuse, and even refusing to participate in voluntary work programs. A study conducted by Physicians for Human Rights determined that the average duration of solitary confinement in ICE detention is 29 days. The United Nations considers solitary confinement for more than 15 days to be torture.

Our recommendations

Prohibit the use of solitary confinement in immigration detention. It is critical to ensure that practices analogous to solitary confinement cannot be misused to circumvent its prohibition.
