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.

Sanctuary Cities Come Under Scrutiny, As Does Federal-Local Immigration Relationship
The killing of a young woman in San Francisco by an unauthorized immigrant coincided with the Obama administration's rollout of the Priority Enforcement Program, a new vehicle for improving federal-local relations on immigration enforcement. The tragedy has rekindled debate over the role of "sanctuary" cities and propelled illegal immigration to the forefront of the 2016 presidential race.

Finding Connections: The Nexus between Migration and Corruption
Though relatively unexplored, there are myriad links between migration and corruption. This article offers ten connections between migration and corruption, from the facilitation of illegal migration and humanitarian protection to impediments to development benefits. The migration-corruption nexus is examined in three case studies: human trafficking in Nigeria, police extortion in Latin America, and a Norwegian return scheme for Iraqi asylum seekers.

Destination China: The Country Adjusts to its New Migration Reality

Faced with rising numbers of foreign entries (long- and short-term), China in 2012 adopted new legislation to manage its migration flows—the first reform to the country's immigration law since 1985. With an underlying tension in the legal framework between restricting immigrants deemed unwanted and welcoming those viewed as desirable, this feature examines the exit-entry law's key points.

Border Controls under Challenge: A New Chapter Opens

In 2014 governments in Europe, North America, and Australia reacted to significant mixed flows of humanitarian, economic, and family-stream migrants with a range of new policies. These came as some migrants presented themselves to authorities for processing rather than trying to evade U.S. or European border controls, with the knowledge that backlogs and little political will for the removal of vulnerable populations might allow them to stay for extended periods.

Executive Power Showdown: Congress and White House Quarrel over Immigration Spending

Though a faceoff between the U.S. executive and legislative branches is now in the courts, with President Trump's decision to declare a national emergency so he can allocate more money for construction of a border wall, a less-noted dispute has been taking place over the Department of Homeland Security's decision to add thousands more immigration detention beds than Congress provides annually, as this article explains.

A Wall Cannot Fix Problems at Border; Smart Solutions for Asylum Crisis Can

What President Trump calls a border crisis is in fact a crisis in the asylum system—one worsened at every turn by his administration’s harsh policies and rhetoric. Rather than spend $5.7 billion on a wall, it would be far more effective to use the money to retool an overwhelmed asylum system, adapt outmatched border enforcement infrastructure to respond to the changing composition of arrivals, and work cooperatively with Mexico to tackle the factors propelling Central Americans to flee.

An “Informal” Turn in the European Union’s Migrant Returns Policy towards Sub-Saharan Africa

The European Union's focus on formal readmission agreements with migrant-origin countries to manage the return of irregular migrants and failed asylum seekers has given way since 2016 to informal arrangements. This article explores the potential effect that nonbinding readmission pacts could have on migrant returns to sub-Saharan Africa, where return rates from EU Member States have been low.

Pushing Migration to the Forefront, Populists Make New Strides

2018 proved a banner year for far-right populist movements in Europe and the Americas. They claimed the presidency of Brazil, sparked the collapse of the Belgian government, and—whether in or out of office—put a harder-edged stamp on migration and asylum policies in Austria, Denmark, Hungary, Italy, Sweden, and beyond.
