About this project

Tracking 287(g) is a public interest journalism project documenting local law enforcement agencies that have partnered with U.S. Immigration and Customs Enforcement under Section 287(g) of the Immigration and Nationality Act.

The 287(g) program allows ICE to delegate immigration enforcement authority to state and local agencies through a formal Memorandum of Agreement. Officers at participating agencies can be trained and authorized to perform immigration enforcement functions — including identifying, processing, and detaining people for removal.

Why this matters

There is no single, up-to-date, machine-readable public database of 287(g) agreements. ICE publishes a list of current participants, but it lacks historical data, contact information, agreement terms, and the context needed for accountability journalism and community organizing.

We built this tool to fill that gap — and to make the data as findable as possible, so that people can look up their own local agencies.
