Immigration Policy

Immigration policy is the body of laws, regulations, and practices through which states decide who may enter, stay, work, and become citizens, and under what conditions. It covers admissions, visas, asylum, family reunification, border enforcement, and integration measures. Rogers Brubaker's comparison of French and German citizenship showed how national traditions shape policy, and Stephen Castles and Mark Miller described an age of migration in which states struggle to control flows. Gary Freeman distinguished client, interest group, and other politics of immigration, and James Hollifield described the liberal paradox between economic openness and political closure. Saskia Sassen argued that states have limited control over global forces, while Douglas Massey showed that tougher border enforcement in the United States reduced circular migration and increased permanent settlement. Wayne Cornelius and Christian Joppke analyzed the gap between policy goals and results. Critics point to rights violations in detention and deportation, and scholars such as Didier Fassin and Nicholas De Genova examined how illegality is produced by law. Others defend controls as an expression of sovereignty and democratic choice. Today immigration policy is central to research on citizenship, borders, labor, and political conflict.
