ICE’s Shadow Warrants: How Administrative Warrants Let Texas Police Become Immigration Agents

Three Texas cities recently found themselves under Gov. Greg Abbott’s gun for adopting policies that restrict local police from fully cooperating with ICE’s administrative warrants. These warrants are a key tool in the Trump administration’s aggressive deportation machine, especially in Texas, home to an estimated 1.7 million undocumented immigrants.

Unlike criminal warrants, which require a judge’s approval, ICE’s administrative warrants are issued internally by the agency without independent judicial oversight. There are two types: Form I-205, based on final deportation orders from immigration courts, and Form I-200, targeting people suspected of immigration violations, including those still fighting their cases. This means ICE can order arrests on largely civil grounds, sidestepping the Fourth Amendment’s protections against unreasonable searches and seizures.

In February 2025, ICE dumped more than 700,000 of these administrative warrants into the National Crime Information Center database, which local police use during routine stops or calls. The sheer volume is staggering. “That is a huge number of warrants to be added to the database,” said Lindsay Nash, co-director of the Immigration Justice Clinic at Cardozo School of Law. But the Department of Homeland Security (DHS) has refused to clarify how many are currently active or how often they lead to wrongful detentions.

Legal experts warn that these warrants undermine constitutional safeguards. Michael Kagan, director of the Immigration Clinic at UNLV, explains that ICE officers don’t answer to any independent authority when issuing these warrants, and police stops based on them risk becoming open-ended detentions without probable cause. This “short circuit” around due process turns local law enforcement into immigration enforcers, exposing communities to abuses.

DHS defends administrative warrants as essential tools, claiming all individuals served have had “full due process” and a “final order of removal.” Yet civil rights advocates highlight persistent errors and outdated warrants lingering in the system, which can lead to innocent people being wrongfully detained.

Abbott’s fight with Houston, Dallas, and Austin illustrates the stakes. After the cities adopted policies limiting ICE cooperation to protect residents, Abbott threatened to yank millions in public safety funding. Houston’s revised ordinance removed language that prevented police from detaining people solely on administrative warrants—a move critics call a “backdoor repeal.” Dallas dropped its ban on prolonging detentions until ICE arrives, while Austin softened its stance to require contacting ICE “when operationally feasible” but still barred arrests solely on administrative warrants.

This tug-of-war exposes the dangers of administrative warrants: a secretive, unchecked enforcement mechanism that erodes civil liberties while weaponizing local police against immigrant communities. As Abbott doubles down and ICE expands these warrants, Texans face a grim reality where constitutional rights become collateral damage in the immigration enforcement war.
