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.

Texas Leads Resurgence in Restrictive State Actions on Immigration Enforcement

A new hardline immigration law in Texas marks the resurgence of state-level restrictionist activism that had stalled in 2012 amid adverse federal court rulings. The Texas law, SB 4, is designed to end sanctuary policies in jurisdictions across the state, and closely mirrors aspects of Arizona's controversial 2010 law, SB 1070.

Despite Little Action Yet by Trump Administration on Sanctuary Cities, States and Localities Rush to Respond to Rhetoric

While Donald Trump often pledged as candidate to strip federal funding from jurisdictions—known as sanctuary cities—that do not fully cooperate with federal immigration enforcement, no direct action blocking funding has yet occurred. Still, strong statements from the President and Attorney General have spurred a flurry of responses by state and local governments, some adjusting their policies to cooperate fully, others setting limits.
