Abstract
David Miller offers a liberal realist defence of immigration control grounded in cosmopolitan ideals of self-determination, fairness and integration. But a commitment to liberal values requires a commitment to more open borders than he admits. A part of the problem is that the notion of open borders Miller criticises is under-theorised. A deeper problem is that immigration control itself is inconsistent with important liberal values – notably the values of freedom and equality. This is a concern because it is the freedom and equality not only of immigrants but also of citizens that is threatened by the closing of borders.
