Abstract
This review essay takes stock of the state of the field and speculates on its future. I highlight three themes. First, as the field has expanded, theorists come to migration from different methodological stances. While liberalism, broadly construed, continues to be the dominant framework, theorists increasingly find resources in feminist thought and philosophy of race. Second, normative theorists now engage much more deeply with the empirical literature, in some cases combining fieldwork and normative theory. This has led to a shift from broad questions about the morality and legitimacy of border controls to more specific issues such as the ethics of refugee camps and repatriation, the realities of immigration enforcement and surveillance regimes, and the role of race and racialization in immigration policy, as well as challenges specific to particular geographical regions. Third, migration raises broader issues of political theory, challenging us to reimagine political and social boundaries for a mobile world.
