Immigration has taken on renewed prominence in both domestic and international politics. Typical approaches to this pressing theoretical and policy problem, however, focus on either domestic politics (e.g., filling labor needs and integrating migrants into society) or international relations (e.g., international law or norms regarding the treatment of migrants). In this sense, work on immigration has coalesced around two ways of seeing this problem, one micro, one macro, and neither one related to foreign policy. This is particularly unfortunate given that a foreign policy approach—grounded in “mid-range theory,” an “actor-specific” approach, and a sensitivity to factors both above and below the state level—has the potential to add a great deal to our understanding of immigration in IR. A review of the literature reveals two approaches to immigration in IR. The first, largely grounded in the methods and assumptions of political economy, focuses on the “pull” or demand factors that incentivize and regulate migration to a receiving country. The second focuses on “push” factors that drive people from their homelands. This latter approach concentrates on displaced populations, human rights norms, and institutions and cooperation among states. Both approaches contribute a great deal, but are, unfortunately, isolated from each other: an outcome that is at least partly attributable to an arbitrary and politically expedient distinction between “refugees” and “ economic migrants” that countries found it in their interests to make in the aftermath of World War II. This discussion of immigration and foreign policy thus begins by surveying the theoretical and empirical landscape and providing a framework with which to understand contributions thus far. The following section will highlight three major themes emerging in an innovative new body of research. Fundamentally, these themes revolve around integration: whether it is the integration of security into immigration studies (typically dominated by an economics-based approach), of identity concerns into the public’s immigration preferences, or a focus on the multiple actors located in between the domestic public and international regimes. Suggestions for future research will conclude our discussion.

The interdisciplinary field of migration studies is broadly interested in the causes, patterns, and consequences of migration. Much of this work, united under the umbrella of the “new economics of migration” research program, argues that personal networks within and across households drive a wide variety of migration-related actions. Findings from this micro-level research have been extremely valuable, but it has struggled to develop generalizable lessons and aggregate into macro-level and meso-level insights. In addition, at group, region, and country levels, existing work is often limited by only considering migration total inflows and/or total outflows. This focus misses many critical features of migration. Using location networks, network measures such as preferential attachment, preferential disattachment, transitivity, betweenness centrality, and homophily provide valuable information about migration cascades and transit migration. Some insights from migration research tidily aggregate from personal networks up to location networks, whereas other insights uniquely originate from examining location networks.

During crisis events such as humanitarian conflicts, population displacement, natural disasters, and others, some people are more vulnerable to long-term physical, psychological, and overall adverse outcomes. Aspects of context that affect vulnerability include: (a) the nature of the hazard or conflict event; (b) the geographic location and structural surroundings; and (c) involvement of key groups during crisis. The nature of the event includes barriers for access to well-being in high-income and low-income contexts, the speed of onset of the hazard, the scope and type of hazard (localized or catastrophic, natural or technological, and other factors). Geographic location and structural surroundings include factors such as isolation caused by an island context, structural mitigation (such as earthquake-resistant construction), pollution and environmental exposure, and implementation of land use planning or sustainable farming. Finally, with regard to involvement of key groups in crisis, it is important to consider ways in which group coordination, logistics, cultural competency, public policy, social movements, and other mechanisms can exacerbate or improve conditions for vulnerable groups. Groups more likely to experience adverse outcomes in disasters include: ethnic and racial minoritized persons, people considered to be low caste, women, children, infants, sexual minorities, religious minorities, elders, and immigrants and refugees. Displacement and relocation are associated with specific increases in exposure to food insecurity, human trafficking, and reduced access to reproductive care. Contextual factors are also related to the severity of the adverse outcomes these groups experience in crisis. These factors include access to healthcare, access to education, and economic status. There are also unique groups whose needs, social systems, and cultural factors increase barriers to evacuation, accessing warning information, or accessing safe sheltering. These groups include persons with functional and access needs including medical or cognitive impairments, elderly individuals, people with companion animals, and people with mental illness.

African borders, which mostly follow the contours of the former colonies, are widely regarded as artificial and yet have enjoyed remarkable longevity. On the one hand, there have been relatively few serious secessionist and/or irredentist bids. On the other hand, a limited number of border disputes have been settled and mostly without recourse to conflict. This is often attributed to the willingness of states to accept the principle of the intangibility of borders inherited from colonialism and the associated legal principle of uti possidetis. Most claims to secession are based on a preexisting sense of territoriality, whereas there are relatively few that are premised on the rights of peoples to self-determination. It has been pointed out that claims to secession are often tabled as a bargaining position rather than as a nonnegotiable demand. However, the secession of South Sudan has created a genuine precedent, and there has been an upsurge of secessionist movements that reflects this reality. In addition, there has been a proliferation of fresh border disputes, which reflects the increased competition for valuable resources such as oil. This would suggest that some of the landscape of border politics is undergoing a shift. However, a number of factors continue to work in favor of the reproduction of existing borders. Paradoxically, the fact that guerrilla insurgencies tend to breed in borderlands, from where movements either aspire to take over the existing state or seek to carve out zones of de facto control, means that the borders themselves are not challenged. War economies depend on transboundary flows in which local populations themselves are deeply invested. Moreover, the flight of displaced populations and refugees toward borders may create greater insecurity at the margins but also tends to reinforce borders in both a legal and a practical sense. Finally, the struggle to determine the basis on which trade and transport is managed involves associational actors operating at the national level. Equally, fishermen, herders, farmers, and other local actors frequently invoke national affiliations to justify their own right to exploit resources within border zones. At the border itself, one observes a convergence of international, national, and local political scales in a particularly striking manner.

There has been renewed academic interest in the security impacts of forced migration since the start of the Syrian civil war in 2011 generated more than 5 million refugees, most of whom fled to neighboring countries and to Europe. Researchers are, for instance, increasingly working to identify how the type, severity, and perpetrator of political violence affect patterns of displacement, such as whether forced migrants cross borders or remain in their home country. Though much of the discussion in the security studies context continues to center on forced migration flows as a conduit for civil war, international terrorism, and refugees and internally displaced persons (IDPs) as perpetrators, scholars also have begun to focus attention on the ways in which refugees and the internally displaced can become the targets of political violence in the receiving state. Following the path of earlier qualitative research recognizing that displaced populations rarely become militarized, studies of a more quantitative orientation are now working to isolate the conditions under which forced migration leads to varying forms of political violence. Another important and growing area of focus is on how resettlement of the displaced affects the dynamics of violence in the origin country, including the potential for conflict recurrence. Efforts to study security impacts of forced migration more systematically have increased alongside the availability of new data and more diverse analytical tools and methods. Still, many important dimensions of the forced migration–conflict connection remain to be explored, and innovative research as well as new data collection efforts are necessary. Integrating insights from other fields, including economics, psychology, and sociology, and returning to the task of theory-building based on case-study research offer a promising path forward.

Intraregional migration of cross-border workers, unskilled and temporary contract workers, undocumented migrants, highly skilled professionals, and refugees characterize the migration landscape in Africa and is reflected in distinctive and changing configurations in the different subregions: labor migration in the west and central areas, movement of refugees in the eastern and southern areas, and migration of skilled professionals from west and east to southern Africa. Migrants and refugees in Africa share a number of common features: both are caused in large part by a set of interrelated factors—conflicts, underdevelopment, poor governance, and economic and social deprivation—and movements are confined largely to the continent. Youth unemployment, a major trigger for irregular migration, together with emigration of skilled professionals, pose serious challenges for many countries; remittances from the diaspora, though a lifeline for poor families left behind, do not compensate for the loss of skills. The refugee situation is highly dynamic and fluid. The sheer numbers of refugees in Africa, their composition, and the challenges they face and the limited success obtained thus far in the search for a permanent solution require sustained efforts in what is regarded an African problem requiring essentially an African solution.

The European Union (EU) migration crisis has been part and parcel of a conglomerate of crises that have affected the EU since the late 2000s, as have the financial and sovereign debt crisis, “Brexit,” the Russia–Ukraine conflict, as well as tensions within transatlantic relations. Scholarship on the EU has devoted much attention in assessing what the migration crisis means for EU integration at large. In particular, EU scholars are interested why the migration crisis has led to political gridlock and a renationalization of border controls rather than a deepening of integration. While they differ in their explanations, these explanations shed light on different aspects of the crisis and are far from mutually exclusive. Scholars who are more interested in the area of EU Justice and Home Affairs (JHA) largely agree with EU theorists that the field suffers from an incomplete governance design, the dominance of EU member states, and weak supranational capacities. Their analysis also focuses on intra-EU dynamics but offers a more nuanced empirical assessment of relevant EU institutions and decision-making in the course of managing the migration crisis. This growing body of research produces valuable insights and largely confirms existing scholarship, including that on the growing securitization and externalization of EU asylum and migration policy. The EU’s understanding as a norm-based power is particularly challenged by the migratory movements in the wake of the crisis. A small but growing scholarship analyses how the EU is balancing its non-entrée policy with its legal obligation, and what kind of governance arrangements result from that. While this scholarship has enriched our understanding of the EU migration crisis, it has not generated a major refinement of the standard approaches of EU theorists and JHA scholars. To further enrich the literature on the migration crisis, scholars should go beyond studying the dynamics of EU decision-making and the role of EU institutions. Such an approach should engage more systematically with international actors and institutions that have the capacity to influence EU migration policy. At the same time, global phenomena such as war, poverty, or climate change should also be taken into account in assessing the EU’s room for maneuver in handling migratory pressures. Future research on the migration crisis as well as on migration challenges should thus not only connect with other subfields of political science, such as policy analysis or international relations, but also open up to other disciplines such as law, demography, or environmental studies.

The devastating Syrian civil war that began after the Arab Spring in 2011 has reminded the international community of the many consequences of civil war. However, this conflict is simply one of many ongoing conflicts around the globe. Civil war has a number of effects on individual lives, the country experiencing the conflict, as well as the international system more broadly. The humanitarian costs of civil war are steep. Individuals are negatively impacted by civil war in a myriad of ways. Three main areas of research are of interest: mortality, physical and mental trauma, and education. Several factors increase the number of deaths in a civil war, including a lack of democracy, economic downturns, and foreign assistance to combatants. Even if civilians survive conflict, they are likely to endure trauma that affects both mental and physical health. Strong evidence indicates that civil war spreads infectious diseases and severely diminishes life expectancy. Mental health is also likely to suffer in the face of conflict, as individuals often must overcome debilitating trauma. Finally, children are particularly susceptible in civil war settings. Children are often unable to continue their education as a consequence of civil war because combatants often target schools strategically or the state is unable to fund education as a result of funneling resources to the conflict. Civil wars also pose a number of threats to the state itself. First, a state that has experienced a civil war is much more likely to have another civil war in its future. Conflict recurrence has been explained through the type of settlement that concludes the initial civil war, institutions that may prevent recurrence like proportional representation, and the role of third parties in providing peace-ensuring security guarantees. Beyond recurrence of war, scholars have looked at the impact that civil wars have on state-level institutions, including democratization. While most state-level effects of civil war seem to be deleterious, there may also be positive effects, specifically in terms of female representation. Civil war in sub-Saharan Africa has been shown to increase the number of female representatives, perhaps providing an avenue for gender equality. Civil wars have ripple effects that impact neighboring countries and the international system more broadly. Proximate states are often challenged with an influx of refugees that may burden social programs or facilitate the spread of diseases and illicit arms. However, positive consequences of hosting refugees may include trading opportunities or economic growth from remittances. Moving beyond proximate states, civil wars have consequences for the entire globe. For example, civil wars have been demonstrated to spur international terrorism. The civil war literature has explored the various effects of conflict at the individual, state, and interstate level.
