How participation has grown
Active 287(g) agreements by model, since Dec 2024.
6 agreements.
Experimental (#162). Each line counts active agency–model agreements, so an agency with two models counts once per model. Changes are dated by when they appear in ICE's published list; the Dec 2024 level carries everything signed before then, and the archive has no snapshots between mid-Dec 2024 and early Mar 2025, so the lines run flat there.
News coverage of ICE's 287(g) program in Montana
Updated July 7, 2026
ICE lists six participating 287(g) agencies in Montana, placing the state in the middle of the national pack by agency count and roughly in line with Mountain West neighbors like Idaho and Utah. The most consequential fights over local immigration cooperation have played out not through those agreements but in political and legal clashes — the state pressing Helena and Gallatin County over alleged noncooperation, and Gallatin County ultimately ending its long-standing 287(g) pact in June 2026.
