States have limited ability to respond to sweeping immigration enforcement as private prison companies use their federal contracts with ICE to shield themselves from state regulation. Prison contractors have successfully sued over state laws that aimed to regulate or ban private immigration detention, arguing their federal contracts entitle them to immunity from direct state oversight.

Why it matters

The Trump administration's immigration crackdown has led to a surge in the number of migrants detained, with a majority held in private facilities. This legal precedent gives private prison companies significant power to avoid state-level oversight and accountability, even as they play a central role in the federal government's immigration enforcement efforts.

The details

Prison contractors have sued over laws in California, Illinois, Washington, and New Jersey that sought to regulate or ban private immigration detention centers. The contractors have argued that their federal contracts with ICE grant them immunity from direct state regulation, and federal appeals courts have so far sided with the companies in these cases.

  • In January 2026, ICE was holding over 75,000 people in immigration detention.
  • The Trump administration's immigration crackdown began in 2017.
