Part of that operation includes what’s known as the federal 287(g) program. Established in 1996, it allows U.S. Immigration and Customs Enforcement, whose work is normally carried out by federal officials, to train state and local authorities to function as federal immigration officers.
Under 287(g), for example, local police officers can interview people to determine their immigration status. They can also issue immigration detainers to jail people until agents with the U.S. Immigration and Customs Enforcement take custody.

Since Trump began his second term in January, ICE has increased 287(g) agreements from 135 in 25 states in December 2024 to 628 in 40 states as of May 28, 2025.
As a criminal justice scholar, I believe the surge of 287(g) agreements sets a dangerous precedent for local policing, where forging relationships and building the trust of immigrants is a proven and effective tactic in combating crime. In my view, the expansion of 287(g) will erode that trust and makes entire communities – not just immigrants – less safe.
