From Jailers to Case Managers: Redesigning the U.S. Immigration Detention System to Be Effective and Fair

Highlights

U.S. immigration detention cost up to $200 per person per day in fiscal year 2021. Shifting to case management and supervised release can reduce costs and improve outcomes.

  • In fiscal year (FY) 2021, detention consumed $2.8 billion of the $8.4 billion U.S. Immigration and Customs Enforcement (ICE) budget. Yet the nondetained caseload exceeded 3.2 million in September 2020—most without meaningful supervision or case management. 
  • COVID-19 outbreaks struck more than 100 ICE facilities by mid-2021; in June 2020, facilities had infection rates five times higher than prisons and 20 times higher than the general U.S. population. 
  • Pilot programs show that case management works: ICE's Family Case Management Program achieved 99 percent compliance with immigration court hearings at a cost of $38 per family per day, versus $238 for family detention. 

The United States operates a sprawling immigration detention system of about 150 facilities that has long been controversial for its prisonlike conditions and health risks—risks that have come into even sharper focus during the COVID-19 pandemic. Yet statutorily, immigration detention is a function of civil, not criminal, law. Its aim is not to punish but to ensure immigrants appear for their immigration appointments and court dates and leave the United States in a timely fashion if they are ordered removed.

After years of growth, policies put in place since the onset of the pandemic in 2020 and the start of the Biden administration in early 2021 greatly reduced the number of immigrants held in detention. With the scale of detention well below its peak in fiscal year 2019, this is an opportune moment to rethink the role and nature of custody in the U.S. immigration enforcement system.

This report explores the limitations of the current approach to immigration custody and proposes a less punitive and less costly alternative that would use release with supervision and case management as the prevailing custody method whenever possible, while still ensuring compliance with the requirements of immigration and removal processes. The report also examines the fundamental changes to the culture and operations of the Department of Homeland Security and its component immigration agencies that such a shift would entail.
