II. Basic Primer on German Citizenship Law
1. A person can become a German citizen in one of three ways: by birth, by adoption as a minor, or by naturalization.
2. A person may be born a German citizen by either jus sanguinis, i.e., through descent from his/her parents, or jus soli, i.e., through place of birth.
3. As a general rule, a child born to a German citizen parent automatically acquires German citizenship at birth through jus sanguinis, regardless of the place of birth. There are exceptions under present law, however, and have been many in the past. For more information about how German citizenship may be transmitted by a German parent, please contact your local Staatsangehörigkeitsbehörde (or Standesamt, in some parts of Germany).
4. As of January 1, 2000, a child born in Germany to non-German parents automatically acquires German citizenship at birth by jus soli if: (1) at least one parent had lived legally in Germany for at least eight years prior to the birth; (2) at the time of the birth, that parent had a permanent residence permit (either an Aufenthaltsberichtigung or, for the three years prior to the birth, an unbefristete Aufenhaltserlaubnis). Note that:
a. The child must choose between German nationality and the nationality of his/her parents before he/she turns 23 years of age, unless it is legally impossible for him/her to give up his/her parents' nationality, in which case he/she must apply to the German authorities for dual nationality before turning 21.
b. Special rules apply to children born between February 2, 1990, and December 31, 1999, who have until December 31, 2000, to apply for German citizenship.
c. Those born in Germany to non-German parents before February 2, 1990, have no claim to German citizenship under this law.
d. For more information, please contact your local Staatsangehörigkeitsbehörde or the nearest office of the Ausländerbeirat (Foreigners Advisory Council).
5. A person can become a German citizen at some time after his/her birth through the Einbürgerung (German naturalization) process, i.e., by applying for German citizenship and satisfying certain legal requirements. One requirement is the formal renunciation of all other nationalities, unless legally impossible under the laws of the applicant's home country. For more information about German naturalization process, please contact your local Staatsangehörigkeitsbehörde (or Standesamt in some parts of Germany) or the nearest Ausländerbeirat.
6. A child under age 18 adopted by a German citizen automatically becomes a German citizen as of the time of the adoption.
7. A German citizen has no right to renounce his/her German citizenship but generally is allowed to do so, so long as he/she does not become stateless as a result. While there are exceptions, as a general rule a German citizen may not give up citizenship to avoid an obligation of that citizenship, e.g., military service. For more information about loss of German citizenship, please contact your local Staatsangehörigkeitsbehörde (or Standesamt).
