I provide an alternative to the two prevailing accounts of justice in immigration policy, the free migration view and the state discretion view. Against the background of an internationalist conception of domestic and global justice that grounds special duties of justice between co-citizens in their shared participation in a distinctive scheme of social cooperation, I defend three principles of justice to guide labor immigration policy: the Difference Principle, the Duty of Beneficence, and the Duty of Assistance. I suggest how these (...) principles are to be applied in both ideal and nonideal circumstances. Finally, I argue that the potential conflict between these principles has often been overstated, and propose priority rules for genuine cases of conflict. (shrink)
