A child born in the Federal Republic of Germany to foreign parents acquires German citizenship in addition to any foreign citizenship if at least one parent has
- has had his or her habitual residence in Germany legally for eight years without interruption
- has a permanent right of residence or, as a citizen of Switzerland or a member of his or her family, a residence permit on the basis of the Agreement of 21 June 1999 between the European Community and its Member States, of the one part, and the Swiss Confederation, of the other, on the free movement of persons (Federal Law Gazette 2001 II p. 810).
The acquisition of German citizenship is entered in the birth register by the registry office.
