State & Local Enforcement

Amid growing public concern over illegal immigration, state and local governments in the United States increasingly have waded into an immigration enforcement arena that historically was viewed as the preserve of the federal government—enacting legislation and ordinances seeking to reduce illegal immigration and signing on to federal-state law enforcement partnerships such as the 287(g) initiative. The research here traces the rise of state and local activity in the post-9/11 environment.

The Limits of the Go-It-Alone Approach: U.S. Migration Management Increasingly Requires Other Countries’ Cooperation

The U.S. immigration enforcement system increasingly depends on other countries to help halt irregular movements through the Americas and accept the return of unauthorized migrants. Foreign governments play a crucial and yet underappreciated role in migration management, and can either aid or frustrate U.S. border-control aims, as this article explores.

Standoff at Eagle Pass: A High-Stakes U.S. Border Enforcement Showdown Comes to a Small Texas Park

Rising tensions between Texas and the federal government have sparked fears of a constitutional crisis after the state deployed its National Guard to prevent the U.S. Border Patrol from conducting operations in a city park in Eagle Pass, with Texas Governor Greg Abbott saying the “invasion” of migrants triggered the need for action. This article provides an overview of the standoff and the larger context of current and past state-federal tensions over immigration enforcement.

Activism on Immigration by U.S. States Is Back, with New Tactics and Different Targets

Renewed U.S. state activism on immigration has echoes of the early 2010s, when Arizona’s SB 1070 defined a Republican-led push to increase enforcement that was ultimately muted by the courts and public backlash. Newer strategies rely on a novel array of tactics including migrant busing, litigation, and lawmaking. States are also moving in opposite directions, with some expanding rights for unauthorized immigrants, as this article details.

Busing and Flights of Migrants by GOP Governors Mark a New Twist in State Intervention on Immigration

Operations by Texas, Florida, and Arizona to bus or fly asylum seekers and other migrants to Washington, DC, Martha's Vineyard, and other cities have succeeded in drawing attention to the unprecedented pace of U.S.-Mexico border arrivals. Described by some as political pawns, many migrants say the trips have upsides. Consequences aside, the transport of migrants by Republican governors raises the question whether a new era has begun: state-on-state fights over immigration.

Growing State and Local Role in U.S. Immigration Policy Affects Sense of Belonging for Newcomers and Natives Alike

The adoption of immigration measures by state and local governments can affect the sense of belonging not just for immigrants but also for the U.S. born, with impacts on individuals’ wellbeing, their engagement with others, and political participation. As the number of subfederal immigration measures has proliferated in recent years, research suggests this growth could have wider-ranging repercussions than commonly understood.

Revving Up the Deportation Machinery: Enforcement under Trump and the Pushback

The Trump administration has significantly cranked up the immigration enforcement machinery in the U.S. interior. Yet even as arrests and deportations are up in the early Trump months, they remain less than half their peaks. This report demonstrates how pushback from California and other "sanctuary" locations makes it quite unlikely that ICE will be able to match record enforcement levels.

Trump Administration Ratchets up Pressure on “Sanctuary” Jurisdictions

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.

Trump’s First Year on Immigration Policy: Rhetoric vs. Reality
