(UNITED STATES) – A federal court issued a temporary restraining order blocking the Department of Homeland Security from enforcing a new ICE policy that required Members of Congress to wait seven days before visiting immigration detention facilities and barred access to certain field offices.

The order came in Neguse et al. v. U.S. Immigration and Customs Enforcement et al., a case brought by 12 Members of the U.S. House of Representatives. It was initially set for 14 days, allowing lawmakers to resume unannounced oversight visits to detention centers while the case continues.

The challenged policy, imposed by the Trump-Vance administration, applied to congressional oversight visits at ICE facilities where noncitizens are detained. Lawmakers argued that the restrictions conflicted with federal law that lets Members of Congress enter such sites without advance notice.

That dispute centers on Section 527 of the FY2024 DHS Appropriations Act. The statute explicitly allows Members of Congress to visit ICE sites where noncitizens are detained without prior notice.

Congress included that authority as an oversight safeguard. The law identifies unannounced access as a way to prevent abuse, protect human rights, and ensure taxpayer funds are not used to support unlawful or inhumane practices.

The court’s order halted enforcement of the waiting period and the access limits while the lawsuit proceeds. In immediate terms, it restored lawmakers’ ability to conduct surprise inspections at detention centers covered by the statute.

The case followed a series of denied visits in several states. Representatives Danny K. Davis, Jesús “Chuy” García, Delia C. Ramirez, and Jonathan Jackson were denied entry to the Broadview ICE facility in Chicago, Illinois.

Members from California, Illinois, and New Jersey also reported being denied access to immigrant detention facilities in their states. Representative Jason Crow of Colorado was among those affected by the policy.

The denials turned a long-running oversight practice into a direct legal clash over access. Instead of unannounced entry, lawmakers faced a policy that required notice a week in advance and blocked them from some ICE field offices altogether.

ICE officials said the policy was designed to protect the facility and the people detained inside. They said advance notice was needed to allow for security preparations.

That justification now sits against a statute written to permit the opposite approach. Section 527 does not condition access on prior scheduling for Members of Congress visiting facilities where noncitizens are detained.

The lawsuit framed the restriction as more than an administrative change. By limiting who can inspect detention centers and when, the policy touched a power Congress wrote into law in the DHS funding measure for FY2024.

Oversight visits carry practical weight inside the immigration system because they let lawmakers inspect conditions firsthand rather than through briefings or scheduled tours. Unannounced visits also test whether conditions hold up without advance preparation by facility staff.

The order does not end the case. It freezes the policy for 14 days at the outset and gives the 12 House members who sued a chance to keep pressing their challenge while unannounced access remains in place.

At issue is not only entry to buildings, but who controls visibility into a detention system that Congress funds and monitors. For now, the court has answered that question by stopping ICE from enforcing the notice rule and letting lawmakers return to detention centers without warning.
