What is a 287(g) agreement? and how does it work?

Texas Senate Bill 8 (SB 8), passed in 2025 during Texas's 89th Legislative Session, is one of the state’s most significant immigration enforcement laws. SB8 required almost every county in Texas to enter into a mandatory 287(g) agreement, which allows local law enforcement officers to perform specific federal immigration enforcement activities. There are three different models that agencies can select: Warrant Service Officer Model, Jail Enforcement Model, and Task Force Model.
This page features our interactive map built using official data from U.S. Immigration and Customs Enforcement (ICE), and features which model/s counties across Texas have chosen to participate in.
By compiling county-level data, our goal is to provide the most accessible, up-to-date resource for understanding immigration enforcement in Texas. Explore the map to see how these policies shape communities across the state.

Warrant Service Officer Model (WSO)

Under the Warrant Service Officer model, designated local law enforcement officers are authorized to serve ICE administrative warrants inside jails or detention facilities without ICE officers being physically present. This enables local agencies to deliver immigration paperwork and facilitate custody transfers on ICE’s behalf, embedding federal immigration enforcement directly into routine local detention operations.

Jail Enforcement Model (JEM)

The Jail Enforcement Model allows ICE to train county jail staff to identify individuals for immigration enforcement after they are arrested and booked into a local jail. Immigration screening occurs while a person is in local custody and does not require a criminal conviction. As a result, arrests for low-level or nonviolent offenses can lead to ICE detainers, extended detention, and transfer into federal immigration custody, making local jails a primary entry point into the deportation system.

Task Force Model (TFM)

The Task Force model permits certain local officers to question individuals about immigration status during specific law enforcement activities outside of the jail setting. Immigration enforcement can therefore begin during routine police encounters, such as traffic stops or field investigations, increasing the likelihood that everyday interactions with local police result in federal immigration involvement.
