Eminent political theorist Joseph Carens tests the limits of democratic theory in the realm of immigration, arguing that any acceptable immigration policy must be based on moral principles even if it conflicts with the will of the majority.

This paper considers normative questions about the integration of legally resident immigrants into contemporary liberal democratic states. First, I ask to what extent immigrants should enjoy the same rights as citizens and on what terms they should have access to citizenship itself. I defend two general principles: (1) differential treatment requires justi.cation; (2) the longer immigrants have lived in the receiving society, the stronger their claim to equal rights and eventually to full citizenship. Second, I explore additional forms of economic, (...) cultural, social, and political integration. I argue that the integration of immigrants depends upon a process of mutual, but asymmetrical adaptation and that it is precisely because the immigrants have to adapt more that the receiving society bears a greater responsibility to take steps to promote equality between the immigrants and the existing population.
