German law allows (1) persons descending from German nationals of any ethnicity or (2) persons of ethnic German descent and living in countries of the former Warsaw pact (as well as Yugoslavia) the right to "return" to Germany and ("re")claim German citizenship (Aussiedler/Spätaussiedler "late emigrants"; de:Aussiedler). After legislative changes in late 1992 this right is de facto restricted to ethnic Germans from the former Soviet Union.
