The Trump administration aims to significantly increase the use of denaturalization, the historically rarely invoked process of stripping U.S. citizenship from immigrants. Once reserved largely for Nazis, communists, and security threats, denaturalization now can be used for a broad set of criminal acts and, some critics fear, going after immigrants engaging in disfavored speech or political activity.

Birth tourism is at the center of the Trump administration’s legal argument to end the guarantee of birthright citizenship. Estimates suggest the practice is quite rare, and a range of government actions, including enforcement operations on "maternity hotels," has sought to eradicate it. This article examines birth tourism to the United States, offering a look at trends, policy responses, and its role in the legal fight over ending birthright citizenship.

Federal judges have provided significant opposition to the Trump administration’s immigration policies during its second term. The courts have halted or slowed a number of administration initiatives, including invoking the Alien Enemies Act of 1798 to carry out deportations and seeking to end birthright citizenship. This continues a trend of the judicial branch increasingly becoming the policymakers of last resort as presidents turn to executive action in the face of congressional inaction.

President Donald Trump addresses the nation.

U.S. immigration policy, practice, and enforcement changed dramatically over the first year of President Donald Trump's second term, touching most corners of the immigration system. The government has cracked down on unauthorized immigration in the U.S. interior and at the border, expanded scrutiny of immigrants of all legal statuses, and erected barriers for would-be arrivals. This article provides a sweeping overview of the changes that have taken place and assesses their impacts.

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 launched an ambitious campaign to encourage “self-deportation” as a complement to its muscular immigration enforcement operations. While a somewhat similar U.S. attempt in 2008 was considered a failure and international "pay-to-go" programs have occurred on a smaller scale than envisioned by Trump officials, the administration is hoping it can now succeed through an unmatched combination of carrots and sticks, as this article details.

An ICE specialist in cybercrime.

In its bid to ramp up deportations, the Trump administration is granting ICE access to a swath of government databases that were previously off limits for immigration enforcement, including sensitive tax and Social Security records. This article details the growing digital arsenal of government and commercial databases that ICE can tap to identify and arrest removable noncitizens, and how this unprecedented data sharing has its roots in the post-9/11 era.

Unauthorized immigrants in the process of being deported from the United States.

The Trump administration is tapping ancient war-time and national security laws, including the 1798 Alien Enemies Act and 1940 Alien Registration Act, in unprecedented ways for general immigration enforcement. This article examines how the administration is deploying these archaic authorities, previously used for actions including World War II internments and the Cold War-era campaign against communists.

Noncitizens being deported to Ecuador board a military plane in Texas.

In making immigration enforcement its top priority, the Trump administration has bent a broad swath of the federal government to the mission of arresting, deporting, and barring the entry of noncitizens who lack legal status or have been convicted of crimes. The changes represent an unprecedented retooling and remaking of the vast U.S. deportation machinery, as this article details.

President Joe Biden at the White House.

The Biden administration took significantly more executive actions on immigration than its predecessors, including during Donald Trump's first term, although it has been unable to escape criticism for its response to record irregular arrivals at the U.S.-Mexico border. The border overshadowed administration steps to modernize the legal immigration system and rebuild refugee resettlement, as this analysis of Biden's track record explains.

Kamala Harris and Donald Trump speak to supporters

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.

Asylum seekers receive assistance at the Brooklyn Cruise Terminal in New York City.

Hundreds of thousands of asylum seekers and other migrants have gone directly from the U.S.-Mexico border to New York, Chicago, Denver, and other interior cities, hastening what had previously been a much more gradual process. As arrivals have slowed, the situation has stabilized, and cities have managed to find a new normal. This article explains how cities coped initially and examines the longer-term challenges that remain.

President Joe Biden in Mexico City.

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.

President Joe Biden signs an executive order.

In three years, President Joe Biden has surpassed the number of immigration-focused executive actions taken by the Trump administration throughout its entire four-year term, making his the most active U.S. presidency ever on immigration. Yet the Biden administration has been repeatedly accused of inaction at the U.S.-Mexico border, where record levels of migrant encounters have occurred. This article reviews the Biden track record on immigration.

The U.S. Coast Guard interdicts a vessel with Cuban migrants.

Amid the highest Caribbean maritime migration levels in a generation, the Biden administration is relying on a carrot-and-stick strategy it honed amid record unauthorized migration at the U.S.-Mexico border. The approach, combining limits on asylum, expanded legal pathways, and international enforcement partnerships, could be increasingly important if maritime migration rises, as this article explains.

New York City Mayor Eric Adams meeting with asylum seekers.

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.

MPI President Andrew Selee and two colleagues who joined him at the U.S.-Mexico border to examine increasingly sophisticated U.S. Customs and Border Protection operations discuss the evolution of policies and procedures to address asylum seekers and other migrants arriving at official ports of entry.

Expert Q&A, Audio

How are U.S. border operations and policies evolving at the U.S.-Mexico border to address rising and diversifying flows? And what is driving increasing immigration from across Latin America, the Caribbean, and beyond? MPI President Andrew Selee speaks with two colleagues who traveled from one end of the nearly 2,000-mile boundary to the other, touring U.S. Customs and Border Protection facilities and interviewing U.S. and Mexican officials, NGO leaders, and others.

Maine’s immigrant population, though relatively small, is a notably diverse mix of long-settled residents and newcomers from many parts of the world. At a time when the U.S.-born workforce in Maine is shrinking and aging, immigrants contribute essential labor and skills to the state economy. This report sketches a profile of immigrants in Maine, including their origins, educational attainment, workforce characteristics, and the challenges some face.
