ABSTRACT
The world's population is often seen as divided into two exclusive categories, citizens and aliens. We have argued that "internal citizenship" in contrast to "external citizenship" cannot be dichotomized in this way, but should instead be conceived of as membership of a country, based on a number of de facto relations. Effective domicile and a legal status as permanent resident may include even considerable political rights in the host country. The legal dichotomy between citizens and aliens may describe "external citizenship", but it is blind to essential dilemmas caused by international migration.
