Wyoming — Highway Patrol 287(g) creates statewide immigration enforcement, first state police force deputized in Mountain West
Update (May 2026): The 287(g) footprint has grown well beyond the original five sheriffs. As of May 2026 it comprises seven counties (Campbell, Carbon, Crook, Laramie, Lincoln, Natrona, Sweetwater), four towns (Wheatland, Shoshoni, Pine Bluffs, Moorcroft — all Task Force Model, signed April 2026), plus the Wyoming Highway Patrol (~12 troopers certified). Crook County’s agreement took effect Jan 7, 2026 (Task Force + Jail Enforcement + WSO); Lincoln County’s WSO took effect Nov 2025. Uinta County declined 287(g) and holds detainees only via a U.S. Marshals Service agreement. The expanded coverage map is below.
Overview
On July 28, 2025, Governor Mark Gordon formalized a 287(g) Task Force Model agreement between the Wyoming Highway Patrol (WHP) and ICE. This made Wyoming one of the first states to deputize its state highway patrol for immigration enforcement, creating a statewide enforcement net that extends well beyond the five counties with individual sheriff 287(g) agreements.
Key Details
- Agreement signed: July 28, 2025
- Model: Task Force Model (broader authority than Warrant Service Officer model)
- Authority: WHP officers can access ICE databases, determine immigration status, take enforcement action, and develop evidence against individuals violating immigration law
- Cost: No additional cost to the state; free training from ICE
- Scope: Statewide — WHP operates on all Wyoming highways
- Rollout: Phased implementation
Why This Matters
The WHP 287(g) is a force multiplier for a state with vast geography and limited ICE presence (one ERO office in Casper). Any WHP traffic stop anywhere in Wyoming can now become an immigration enforcement encounter. Combined with the five county sheriff 287(g) agreements (Campbell, Carbon, Laramie, Natrona, Sweetwater), this creates near-total coverage of Wyoming’s population centers and major highways.
The November 2025 trucker operation demonstrated how this works in practice: WHP, Laramie County Sheriff, and ICE collaborated on a 3-day operation that produced 40 deportations from commercial vehicle stops near the Colorado border.

ACLU Critique
ACLU of Wyoming Director Antonio Serrano criticized the agreements as being signed without offering the public a chance to comment, and specifically raised concerns about the WHP’s authority to arrest undocumented immigrants across the five 287(g) counties plus anywhere along Wyoming’s highway system.
