Border Enforcement

Border Enforcement

_BorderEnforcement

Border enforcement is more than its widely perceived role of border guards patrolling external boundaries and inspectors admitting traffic through ports of entry. While those are key components, border enforcement represents a more holistic function, integrating resources and information at and between all ports of entry—whether air, land, or sea—with consular operations abroad and more. The research presented here examines these varied facets.

President Joe Biden in the White House.

Pandemic-related U.S. policies have led to more than 2.6 million migrant expulsions at the U.S.-Mexico border, expanded public benefits to cover millions more U.S. residents, and offered free COVID-19 vaccines and treatment. Many of these policies are now likely to end as the Biden administration in May 2023 formally declares the pandemic to be over, although what comes next remains unclear.

President Joe Biden at the U.S.-Mexico border.

At his term's midpoint, President Joe Biden has relied on executive action to advance his immigration agenda more than his predecessors, including Donald Trump. Yet many of the changes to interior enforcement, humanitarian protection, and other areas have been overshadowed by the record pace of arrivals at the U.S.-Mexico border, which has presented the administration with major policy and operational challenges.

A migrant scheduled to be deported from the United States is escorted to a charter flight.

Every year, thousands of migrants ordered deported from EU Member States, the United States, and elsewhere are not returned to their origin countries. Why? One reason is the multiple nations that refuse to cooperate on readmitting their nationals abroad. This article explores the motivations behind countries’ lack of cooperation and how deporting states have responded.

The Biden administration’s policy to expel some Venezuelan border arrivals to Mexico marks a significant reversal. For the first time, the U.S. government is invoking the controversial Title 42 expulsions policy not on public-health grounds but as an explicit immigration enforcement measure. The expulsions are being paired with a new humanitarian parole program for up to 24,000 Venezuelans. This article assesses the policy and the uneven treatment of humanitarian migrants by nationality.

Texas Governor Greg Abbott speaks before a briefing on border security.

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.

When large numbers of asylum seekers and other migrants arrive at the borders of Western countries without prior authorization to enter, they are often treated as “spontaneous” arrivals. But migration is almost never truly spontaneous. Our podcast Changing Climate, Changing Migration speaks with David Leblang, a professor of politics and public policy at the University of Virginia, who discusses how climate change fits into the migration calculus.

Historically a country of emigration, Spain rapidly transitioned to become one of Europe’s major immigration destinations in just a few years. Remarkably, this evolution occurred with minimal political backlash, even as the country suffered through a crippling economic and labor crisis. This country profile examines the trends and policies that led to this astonishing development.

Virtually all major U.S. immigration policy reforms have faced lawsuits in recent years, giving federal judges wide latitude to shape national policy. The situation, which began during the Obama administration and has escalated, is a byproduct of congressional inaction and the emergence of immigration as a political wedge issue. This article tracks the trend, which has added new volatility to the immigration system, and places it in context.

The border asylum proposed rule the Biden administration unveiled in February represents a bid to save the U.S. asylum system, not shut it down, as some contend. Whether it can succeed, however, depends on how it is implemented and on other steps that are beyond the bounds of the proposed rule, as this commentary explains.
