Michigan — 287(g) Explosion and ICE Partnership Landscape 2025-2026
Overview
Michigan went from zero 287(g) agreements to seven signed agencies in 2025, making it one of the fastest 287(g) expansions in the country. The state legislature is simultaneously pushing for more participation while a Democratic Senate tries to limit ICE enforcement powers.
287(g) Agreements by Model
Warrant Service Officer Model (jail-based)
Officers inside county jails can serve administrative immigration warrants and hold detainees for ICE pickup.
| County/Agency | Signed | Notes |
|---|---|---|
| Jackson County | March 2025 | First in Michigan. Sheriff Gary Schuette. Oldest active agreement. |
| Berrien County | 2025 | Followed Jackson model |
| Calhoun County | 2025 | Also has IGSA — dual agreement (detention + enforcement) |
Task Force Model (field enforcement)
Officers can conduct limited immigration enforcement during routine police duties with ICE oversight. More aggressive model — requires more training but authorizes broader enforcement.
| County/Agency | Signed | Notes |
|---|---|---|
| Roscommon County | June 5, 2025 | Rural northern MI (FIPS 26143, heatmap score 42) |
| Crawford County | September 2025 | Rural northern MI (FIPS 26039, heatmap score 42) |
| Taylor Police Dept | 2025 | Downriver Detroit suburb, only municipal PD with 287(g) |
Withdrawn/Rescinded
| County/Agency | Signed | Rescinded | Notes |
|---|---|---|---|
| Genesee County | Fall 2025 | Shortly after | Cited staffing duty changes |
| Center Line PD | Fall 2025 | November 6, 2025 | Small Macomb County city terminated contract |
Legislative Pressure
Michigan House Resolution 128 (adopted): Encourages all county sheriffs and local law enforcement to enter 287(g) agreements with ICE.
Michigan Senate Bill 43 (introduced): Would require certain law enforcement agencies to perform immigration enforcement functions — going beyond voluntary 287(g).
Counter-legislation (Democrats):
- SB 508: Reinstates sensitive locations policy (no ICE enforcement in schools, hospitals, churches without warrant)
- SB 509: Prohibits sharing personal info with ICE without judicial warrant (did not advance to floor)
- SB 510: Requires body cameras on immigration officers, limits mask-wearing
- SB 508 and 510 passed committee March 25, 2026 along party lines. Face Republican opposition in House.
IGSA Network (Detention Agreements)
Four county jails hold ICE detainees under IGSAs:
- Calhoun County (Battle Creek) — 630 beds, also has 287(g)
- Chippewa County (Sault Ste. Marie) — 120 beds, Upper Peninsula
- Monroe County (Monroe) — near Ohio border
- St. Clair County (Port Huron) — Canadian border
Combined, these held 346 detainees in early June 2025.
Plus: 5. North Lake Processing Center (Baldwin, Lake County) — 1,800 beds, GEO Group private 6. Romulus warehouse (Wayne County) — 500 beds planned, paused under DHS review
