ICE, within the Department of Homeland Security (DHS), is responsible for enforcing the nation’s immigration laws. Citing limited resources, ICE states that it cannot respond to all immigration violations or act on all persons determined to be removable from the U.S. It therefore prioritizes its enforcement actions. GAO was asked to review ICE immigration enforcement priorities. This report examines, among other things, (1) ICE data on immigration enforcement actions from 2019 through 2022, and the extent to which ICE is reporting data on all immigration detentions; (2) ICE’s implementation of immigration enforcement policies; and (3) ICE data on detentions of select vulnerable populations. GAO analyzed ICE enforcement action data for calendar years 2019 through 2022 (2022 being the most recent year that data were available). GAO also reviewed ICE policies and procedures, and interviewed agency officials. What GAO Recommends GAO is recommending that ICE publicly report (1) data on all detentions of individuals in ICE detention facilities, and (2) its explanation of the methodology used to report detention statistics. DHS did not concur with the recommendations, stating ICE already reports sufficient information. GAO continues to believe ICE should report complete and transparent information on its annual detentions

In the current era of intensified immigration enforcement and heightened risks of deportation even for long-term lawful permanent residents, citizenship has taken on a new meaning and greater importance. There is also growing evidence that citizenship denials in their various forms have become inextricably linked to immigration enforcement. Who is denied citizenship, why, and under what circumstances? This article begins to address these questions by developing a typology of citizen denials and providing an empirical overview of each type of citizenship denial. Taken together, the typology of citizenship denials and the accompanying empirical overview illustrate the close connection between immigration enforcement and citizenship rights in the United States

This study was undertaken because generally available information about local government policy regarding inquiry about immigration status, use of this information, and interaction with federal immigration authorities was limited to a few New Mexico jurisdictions and was not upto-date or complete. The study identifies the variation and reasons for variation in these policies across the state, including the lack of any formal policy, and the function of informal policy. The study introduces the term “policy infrastructure” to refer to the function of written policy, procedure, monitoring and enforcement systems in directing local government employees and contractors, regarding their obligations to use public resources as directed by any policy that exists1 . A study assumption is that where no formal policy exists and where policy infrastructure is incomplete, public employees and contractors may use public resources at their discretion, regardless of consequences for affected persons. The problem motivating the study is the apparent situation in which residents and visitors to New Mexico experience different practices regarding the identification of and treatment related to their immigration status across the state, including within overlapping jurisdictions (e.g., city and county). Such variation in treatment raises questions regarding the extent to which immigrant rights (legal and undocumented) are respected across the state. It raises the question as to whether such variation is consistent with the intent of state and federal civil and human rights. The study was conducted between September and December in 2018, and inquiries were made by phone and formal requests for public records to all 33 counties and the 10 largest cities in the state. Contacts focused on county and city managers, sheriff and police departments and detention facilities operated by local governments. Some level of information was provided by all 33 counties and all cities contacted. A summary of results is shown in Table 1. Analysis of all documents and interview notes is provided below as study findings.

IMMIGRATION DETENTION, IS NEVER IN THE BEST INTERESTS OF THE CHILD AND CONSTITUTES A CHILD RIGHTS VIOLATION.

It is a form of violence that impacts a country’s capacity to achieve the 2030 Agenda for Sustainable Development, especially targets 10.7 and 16.2.4,5 All children, regardless of their legal or migratory status or that of their families, have the right to be cared for and protected from violence, abuse and exploitation. At least 77 countries have laws and policies that allow children to be detained based on their legal or migratory status, and at least 330,000 children globally per year are deprived of their liberty based on their (or their parents’) legal or migratory status.6 Lack of accurate data means this is likely to be a significant under-estimate. While many countries have committed to end child immigration detention, the reality is that even in some countries where legislation does not support immigration detention, it continues to remain in use.7 In 2022, the United Nations Task Force on Children Deprived of Liberty8,9 under the leadership of the UN Special Representative of the Secretary-General on Violence Against Children, made a joint pledge10 at the International Migration Review Forum (IMRF):

1. To conduct evidence-based advocacy and to mobilize all key stakeholders at all levels to scale up child rights-based protective solutions to end the detention of children in the context of migration.

2. To support Member States to harmonize their national legal frameworks with international human rights standards to explicitly prohibit detention of children based on their migration status or that of their families.

3. To involve and amplify the voices of migrant children in determining their best interests in all issues concerning children in legislation, policies, practices, including those related to integration, return and family reunification; as well as access to services, to justice and to remedies for violations of their rights.

4. To support data collection and the dissemination of promising practices on child rights-based protective solutions as alternative measures to end the detention of children in the context of migration.
   This advocacy brief provides an overview of promising practices and lessons learned to end child immigration detention and sets out a range of policy actions needed to scale up efforts to end this form of violence

Previous research shows that the day-to-day behaviors of undocumented immigrants are significantly affected when local law enforcement officials do the work of federal immigration enforcement. One such behavior, which has been widely discussed in debates over so-called sanctuary policies, is that undocumented immigrants are less likely to report crimes to the police when local law enforcement officials work with U.S. Immigration and Customs Enforcement (ICE) on federal immigration enforcement. However, the mechanism that explains this relationship, which is decreased trust in law enforcement, has not yet been systematically tested. Do undocumented immigrants become less trusting of police officers and sheriffs when local law enforcement officials work with ICE on federal immigration enforcement? To answer this question, we embedded an experiment that varied the interior immigration enforcement context in a survey (n = 512) drawn from a probability-based sample of undocumented immigrants. When local law enforcement officials work with ICE on federal immigration enforcement, respondents are statistically significantly less likely to say that they trust that police officers and sheriffs will keep them, their families, and their communities safe, protect the confidentiality of witnesses to crimes even if they are undocumented, protect the rights of all people, including undocumented immigrants, equally, and protect undocumented immigrants from abuse or discrimination.

How does interior immigration enforcement affect the day-to-day behaviors of undocumented immigrants? Although there is some evidence that points to a broad range of “chilling effects” that result when local law enforcement officials work with U.S. Immigration and Customs Enforcement (ICE) on federal immigration enforcement, the academic literature is surprisingly sparse. In this study, we embedded an experiment in a survey (n = 594) drawn from a probability-based sample of undocumented immigrants in order to better understand how the behaviors of undocumented immigrants are affected when local law enforcement officials do the work of federal immigration enforcement. When respondents are told that local law enforcement officials are working with ICE on federal immigration enforcement, they are 60.8 percent less likely to report crimes they witness to the police, 42.9 percent less likely to report crimes they are victims of to the police, 69.6 percent less likely to use public services that requires them to disclose their personal contact information, 63.9 percent less likely to do business that requires them to disclose their personal contact information, and are even 68.3 percent less likely to participate in public events where the police may be present, among other findings.

The Criminal Alien Program (CAP) is a program administered by Immigration and Customs Enforcement (ICE) that screens inmates in prisons and jails, identifies deportable non-citizens, and places them into deportation proceedings. In this Special Report, The Criminal Alien Program: Immigration Enforcement in Travis County, Texas, author Andrea Guttin, Esq., provides a brief history and background on the CAP program. Guttin also includes a case study of CAP implementation in Travis County, Texas, which finds that the program has a negative impact on communities because it increases the community’s fear of reporting crime to police, is costly, and may encourage racial profiling.

Advocates of open borders are fond of claiming that illegal aliens commit fewer crimes than native-born U.S. citizens. That makes perfect sense, they assert, because illegal aliens do not wish to be brought to the attention of law enforcement and risk deportation from the United States. In fact, this report finds that in the states examined, illegal aliens are incarcerated up to five and a half times as frequently as citizens and legal immigrants.

Tech is transforming immigration enforcement. As advocates have known for some time, the immigration and criminal justice systems have powerful allies in Silicon Valley and Congress, with technology companies playing an increasingly central role in facilitating the expansion and acceleration of arrests, detentions, and deportations. What is less known outside of Silicon Valley is the long history of the technology industry’s “revolving door” relationship with federal agencies, how the technology industry and its products and services are now actually circumventing city- and state-level protections for vulnerable communities, and what we can do to expose and hold these actors accountable. Mijente, the National Immigration Project, and the Immigrant Defense Project — immigration and Latinx-focused organizations working at the intersection of new technology, policing, and immigration — commissioned Empower LLC to undertake critical research about the multi-layered technology infrastructure behind the accelerated and expansive immigration enforcement we’re seeing today, and the companies that are behind it. The report opens a window into the Department of Homeland Security’s (DHS) plans for immigration policing through a scheme of tech and database policing, the mass scale and scope of the tech-based systems, the contracts that support it, and the connections between Washington, D.C., and Silicon Valley. It surveys and investigates the key contracts that technology companies have with DHS, particularly within Immigration and Customs Enforcement (ICE), and their success in signing new contracts through intensive and expensive lobbying.

This book is a searing critique of today's immigration systems. Former barrister Steve Cohen declares that these systems are deeply flawed, and takes a fresh look at the ethical and political problems that surround this controversial subject. Cohen proposes that current immigration controls are so inherently racist and irrational that they require the creative dystopian ideas contained within George Orwell's "Nineteen Eighty-Four" to adequately describe them. He seeks to understand the irrationality of these controls - complete with their own brand of newspeak, doublethink, memory holes and thought police - and undertakes an incisive critique of immigration controls, revealing the nightmare world in which refugees, migrants and immigrants find themselves. The book also scrutinizes the latest developments in UK immigration legislation and compares and contrasts the UK experience with that of other countries. "Deportation is Freedom!" is a lively yet thought-provoking read that will captivate anyone who cares about the immigration systems that are shaping our world today. It will be of particular interest to social workers, lawyers, social policy makers and all people politically engaged in immigration campaigning.

On any given day nearly 3000 foreign national citizens are detained under immigration powers in UK detention centers alone. Around the world immigrants are routinely detained in similar conditions. The institutions charged with immigrant detention are volatile and contested sites. They are also places about which we know very little. What is their goal? How do they operate? How are they justified

Inside Immigration Detention lifts the lid on the hidden world of migrant detention, presenting the first national study of life in British immigration removal centers. Offering more than just a description of life behind bars of those men and women awaiting deportation, it uses staff and detainee testimonies to revisit key assumptions about state power and the legacies of colonialism under conditions of globalization.

Based on fieldwork conducted in six immigration removal centers (IRCs) between 2009 and 2012, it draws together a large amount of empirical data including: detainee surveys and interviews, staff interviews, observation, and detailed field notes. From this, the book explores how immigration removal centers identify their inhabitants as strangers, constructing them as unfamiliar, ambiguous and uncertain. In this endeavor, the establishments are greatly assisted by their resemblance to prisons and by familiar racialized narratives about foreigners and nationality.

However, as staff and detainee testimonies reveal, in their interactions and day-to-day life women and men find many points of commonality. Such recognition of one another reveals the goal and effect of detention to be incomplete. Denial requires effort. In order to minimize the effort it must expend, the state 'governs at distance', via the contract. It also splits itself in two, deploying some immigration staff onsite, while keeping the actual decision-makers (the caseworkers) elsewhere, sequestered from the potentially destabilizing effects of facing up to those whom they wish to remove. Such distancing, while bureaucratically effective, contributes to the uncertainty of daily life in detention, and is often the source of considerable criticism and unease. Denial and familiarity are embodied and localized activities, whose pains and contradictions are inherent in concrete relationships.

This book discusses the issues surrounding race, ethnicity, and immigrant status in U.S. policing, with a special focus on immigrant groups’ perceptions of the police and factors that shape their attitudes toward the police. It focuses on the perceptions of three rapidly growing yet understudied ethnic groups – Hispanic/Latino, Chinese, and Arab Americans. Discussion of their perceptions of and experience with the police revolves around several central themes, including theoretical frameworks, historical developments, contemporary perceptions, and emerging challenges. This book appeals to those interested in or researching policing, race relations, and immigration in society, and to domestic and foreign government officials who carry law enforcement responsibilities and deal with citizens and immigrants in particular.

Justice-Free Zones: U.S. Immigration Detention Under the Trump Administration, a research report from the American Civil Liberties Union, Human Rights Watch, and the National Immigrant Justice Center, provides an in-depth examination of the state of immigrant detention. Through visits to five detention facilities, interviews with 150 detained people, and analysis of government data, this report shines a light onto our nation’s treatment of immigrants. Specifically, the findings illustrate how the immigrant detention system has grown since 2017, the poor conditions and inadequate medical care — even before the COVID-19 outbreak, and the due process hurdles faced by immigrants held in remote locations.

Young people in immigrant families are often characterized as a separate population in debates over immigration reform, with distinctive claims and interests as compared to their parents. Bifurcating the undocumented population between children and parents over-simplifies how immigration enforcement impacts families. This article challenges the dichotomy between children and parents by studying how young people who are not direct enforcement targets are nevertheless impacted by immigration enforcement policies, regardless of their own immigration status. These impacts, which I call “secondary immigration enforcement,” often manifest as family separations. To render secondary immigration enforcement visible, I studied 38 young people in Arizona who are living on their own – without either biological parent – at least in part because of immigration enforcement policies. Drawing on in-depth interviews and self-assessments of psycho-social functioning, I describe what secondary immigration enforcement looks like and how it operates. I illustrate that deportation statistics alone fail to capture the extent of immigration enforcement because they do not encompass the complex impacts of secondary enforcement. In addition to the acute disruptions caused by deportations of family members, the young people in the study also experienced family separation as a result of immigration enforcement’s interaction with three other key factors: family dysfunction, extreme poverty, and educational aspirations.

Border enforcement of immigration laws raises the costs of illegal immigration, while interior enforcement also lowers its benefits. Used together, border and interior enforcement therefore reduce the net benefits of illegal immigration and should lower the probability that an individual will decide to illegally migrate. While empirical studies find that border and interior enforcement serve as deterrents to illegal immigration, immigration enforcement is costly and carries unintended consequences, such as a decrease in circular migration, an increase in smuggling, and higher prevalence of off-the-books employment and use of fraudulent and falsified documents.

Navigating Borders into the Netherlands provides a unique in-depth look at human smuggling processes. Based on biographical interviews with smuggled migrants in the Netherlands, the study reveals considerable differences that exist in smuggling's underlying causes, how journeys evolve, and outcomes of the process. This research from an insider's perspective clearly demonstrates that smuggled migrants are not passive actors, there is a broad variety in types of smugglers, and interactions between migrants and smugglers largely determine how the smuggling process evolves.

The Trump administration has declared war on MS-13, the notoriously brutal gang based in El Salvador. A similar initiative launched by the Bush administration in 2005 stifled the gang's activity after several years, but the gang has been able to rebuild itself here since 2012.

Center researchers reviewed more than 500 cases of MS-13 gang members arrested nationwide since 2012. We conclude that this resurgence represents a very serious threat to public safety in communities where MS-13 has rebuilt itself. The resurgence is directly connected to the illegal arrival and resettlement of more than 300,000 Central American youths and families that has continued unabated for six years, and to a de-prioritization of immigration enforcement in the interior of the country that occurred at the same time.

All criminal gangs are a threat to public safety, but MS-13 is a unique problem because of the unusually brutal crimes its members have committed, its success in using intimidation to victimize and control people in its territory, and its focus on recruiting young members, often in schools.

Nevertheless, because such a large share of MS-13 members are not citizens, they are especially vulnerable to law enforcement, and many can be removed from the communities they terrorize. Strategic use of immigration enforcement is a necessary element to disrupting and dismantling MS-13 gangs and any other transnational criminal organization operating in our communities.

The proliferation of sanctuary policies that interfere with cooperation between state and local law enforcement agencies threatens to hamper efforts to stifle MS-13 activity. The federal government must take steps to clarify how federal law permits such cooperation and also must set up consequences for those jurisdictions and officials who impose sanctuary policies.

Causes, Dynamics and Consequences of Migration-related Mortality. A 2018 report by two non-governmental organizations (NGOs) revealed that US Border Patrol agents ‘routinely intimidate, harass, and surveil humanitarian-aid volunteers, thus impeding the administration of humanitarian aid’ along the US-Mexico border. Furthermore, they ‘stab, stomp, kick, drain, and confiscate the bottles of water that humanitarian-aid volunteers leave along known migrant routes’ (La Coalición de Derechos Humanos and No More Deaths 2018). More broadly, through the criminalization of humanitarian assistance and the ‘weaponization’ of the terrain, US authorities make themselves responsible for the suffering, death and disappearance of many people (Morgan-Olsen 2018; Osuna 2018). On the other hand, Border Patrol agents often carry out rescue operations to save migrants, which – they argue – demonstrates ‘their dedication in protecting human life’ (U.S. Customs and Border Protection 2019). They are presented as true humanitarians (Price 2018). According to US President Donald Trump, the problem of border deaths can only be solved with more border control. ‘Border Patrol needs the Wall and it will all end’ was his comment on the death of two children occurred shortly after their crossing from Mexico (Tatum 2018)

Until recently, immigration policy was largely in the hands of a small group of bureaucrats, who strove desperately to fend off “offensive” peoples. Barbara Roberts explores these government officials, showing how they not only kept the doors closed but also managed to find a way to get rid of some of those who managed to break through their carefully guarded barriers. Robert’s important book explores a dark history with an honest and objective style.
