The ramp-up of federal immigration enforcement during the second Trump term has prompted sharp responses from state and local governments, with some limiting cooperation with U.S. Immigration and Customs Enforcement (ICE), or barring agents' wearing of masks or the establishment of immigrant detention facilities. At the same time, some Republican-led jurisdictions have embraced policies to encourage cooperation with ICE. This article traces the rise of "sanctuary" policies and divergent trends.

E-Verify has been heralded as a key way to control unauthorized immigration to the United States, but federal efforts to expand the system stalled. There has been movement at the state level over the past decade, though, and there are signs it may rise in prominence again. This article details the history and challenges of E-Verify, and its limited uptake.

The Trump administration has expanded its use of expedited removal in unprecedented ways, transforming what previously had been a somewhat limited authority into a potent tool to assist with its mass deportations drive. This article traces how the administration has sought to expand the reach of the nearly 30-year-old fast-track power beyond the border.

A quiet political realignment has taken place in the United States. As unauthorized crossings of the U.S.-Mexico border have reached record levels in recent years, Democrats have begun to embrace restrictions at the border that they once reviled, including limits to asylum and expansion of the border wall. This article examines the pivot and how it might affect future U.S. immigration politics and policy.

The Biden administration is on pace to carry out as many deportations as the Trump administration, although an overwhelming number have come in the form of voluntary returns at the border, rather than removals of unauthorized immigrants from the U.S. interior. This shift has echoes of earlier eras and comes as a response to record numbers of unauthorized border arrivals.

Once an obscure section of U.S. law, Title 42 was used to expel unauthorized migrants reaching U.S. borders nearly 3 million times from March 2020 to May 2023. Despite idealized depictions of its impact by some politicians, the order was largely ineffective in deterring irregular migration. Instead, it represented a dramatic break with decades of law providing protection to asylum seekers, as this article details.

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.

The U.S. immigration system is notorious for persistent backlogs and antiquated processes. In recent months, under-the-radar changes have made a dent in the logjam and helped bring the system into the 21st century. But some pandemic-era changes are set to expire, potentially undoing the incremental reforms. This article details the quiet technological and efficiency improvements in U.S. immigration operations.

U.S. cities have spent billions of dollars to provide shelter, health care, and other resources to migrants recently arrived from the U.S.-Mexico border. The exceptional costs, which the New York mayor has described as existential, are due to a unique combination of factors, this article explains, including the large numbers of migrants arriving without local connections and long waits for work permits.

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.

The revised U.S.-Canada Safe Third Country Agreement closes what critics call a loophole that incentivizes unauthorized border crossings of asylum seekers. While responding to Canadian concerns of increasing irregular arrivals from the United States, the change—taken in tandem with U.S. moves at the U.S.-Mexico border—suggests that the Biden administration increasingly wants to rely on neighboring countries to respond to rising asylum claims.

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.

Legal immigration to the United States fell to its lowest level in years during the COVID-19 pandemic, but preliminary data suggest it is returning to previous levels, belying predictions that the public-health crisis had allowed the Trump administration to make lasting, deep cuts. Yet the patterns have changed and persistent case processing backlogs could spell long-term problems, as this article explores.

New Biden administration guidelines encourage immigration prosecutors to support dismissing many low-priority deportation cases and focus on criminals, threats to national security, and other priorities. This move could have a major impact on clearing backlogs in the overstretched U.S. immigration court system, resulting in quicker determinations in removal and asylum cases, where wait times can presently stretch for years.

President Joe Biden has made efforts to overhaul the U.S. immigration system, but could see his administration's agenda slowed by massive backlogs across the immigration system. Case application wait times and immigration court queues have swelled during the COVID-19 pandemic, slowing legal arrivals to the United States and undermining the entire immigration system.

The Biden administration's court-ordered restart of the controversial Migrant Protection Protocols, known informally as the Remain in Mexico policy, puts it in the awkward position of reviving a program it is simultaneously still trying to end. The Trump-era program forced tens of thousands of migrants to wait out the duration of their U.S. immigration court hearings in Mexico and was only questionably successful at deterring unauthorized arrivals.

After the terror attacks of September 11, 2001 the U.S. immigration system was retooled to have a strong national security focus. This restructuring had dramatic effects on government operations and resource allocations, not to mention on the lives of immigrants and the U.S. born alike. Twenty years on from 9/11, this article examines the changes put in place or accelerated as a result of the attacks.

Texas seems set to become chief antagonist to President Joe Biden’s immigration agenda. This article explores Governor Greg Abbott's plans to build new barriers along the border, use state and local law enforcement to carry out arrests of unauthorized immigrants, and strip licensing from federally contracted shelters housing unaccompanied children.

President Joe Biden has grand ambitions to reshape the U.S. immigration system, but his administration has run into early stumbling blocks in rolling back the strict enforcement regime of his predecessor. Administrative resistance, a tangled web of legal agreements signed by the Trump administration, and anxieties about a possible uptick in immigrants and asylum seekers at the border have posed early challenges to Biden’s agenda.

Despite a widespread perception that the Trump administration has drastically slashed legal immigration to the United States, a review of the data shows that temporary and permanent admissions during the period mostly followed previous trends—at least until the COVID-19 pandemic hit. This article examines trends in temporary, permanent, and humanitarian admissions during the administration, and the related policies that could take a more significant bite ahead if left unchanged.

In the United States, Republicans and Democrats are deeply divided on immigration. President Donald Trump and Democratic presidential nominee Joe Biden have offered sharply diverging policy positions, and the outcome of the election is sure to have profound consequences for the U.S. immigration system. Yet this partisan divide is relatively new. Just two decades ago, the parties were much more united on immigrants’ role in the U.S. economy and society.
