Border Security

In an era when countries are increasingly exposed to the opportunities and risks associated with the rising global movement of people, policymakers are rethinking approaches to border controls and border management. These policies and programs run the gamut—from facilitating legitimate mobility of people and trade to thwarting unauthorized movements, the latter a significant preoccupation in the post-9/11 era and as publics have become ever less accepting of unauthorized immigration. The research offered here examines the management of borders, enforcement policies and initiatives, and border security technologies.

Biden at the Two-Year Mark: Significant Immigration Actions Eclipsed by Record Border Numbers

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.

‘Recalcitrant’ and ‘Uncooperative’: Why Some Countries Refuse to Accept Return of Their Deportees

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.

Amid Record Venezuelan Arrivals, Biden Administration Embraces Border Expulsions Policy

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.

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.

Revamping Asylum at the U.S.-Mexico Border: A Workable Rescue?

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.

Imminent End of Formal U.S. Pandemic Emergencies Marks New Era in Immigration Realm

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.
