German nationality law

German citizenship is based primarily on the principle of jus sanguinis. In other words one usually acquires German citizenship if a parent is a German citizen, irrespective of place of birth.

A significant reform to the nationality law was passed by the Bundestag (the German parliament) in 1999, and came into force on 1 January 2000. The new law makes it somewhat easier for foreigners resident in Germany on a long-term basis, and especially their German-born children, to acquire German citizenship.

The previous German nationality law dated from 1913. The amendments to the law under the Nazi regime were repealed by the Federal Republic of Germany (see the article on the Reich Citizenship Law).

History

Prussian law was the basis of the legal system of the German Empire. Prussia's nationality law can be traced back to the "Law Respecting the Acquisition and Loss of the Quality as a Prussian subject, and his Admission to Foreign Citizenship" of 31 December 1842, which introduced Jus sanguinis to the country. Until 1913, however, each German state had its own nationality laws, those of the southern ones (notably Bavaria) being quite liberal. In 1913, the Nationality Law of the German Empire and States (RuStAG) of 22 July 1913 standardized the law in all of the German Empire. It had been operational until the 1999 reforms.

Under the Third Reich, German nationality law was extended to Austria in 1938 under the Anschluss which annexed Austria to Germany. On 27 April 1945 the Republic of Austria was re-established and conferred Austrian citizenship on all persons who would have been Austrian on that date had the former (pre-1938) nationality law of Austria remained in force. Such persons lost their German nationality automatically. Also see Austrian nationality law.

Birth in Germany

Children born on or after 1 January 2000 to non-German parents acquire German citizenship at birth if at least one parent:

• has a permanent residence permit; and
• has been residing in Germany for at least eight years.

Such children will be required to apply successfully to retain German citizenship by the age of 23. Assuming the laws (very unlikely) are not changed prior to 2023, they will normally be required to prove they do not hold any other foreign citizenship. The only exceptions are EU citizens and citizens of countries where it is impossible to lose your citizenship, like Morocco or Iran, for example.

Parents who are citizens of European Economic Area states or Switzerland are eligible to receive permanent resident permits after five years.

Descent from a German parent

A person born of a parent with German citizenship at the time of the child's birth is a German citizen. Place of birth is not a factor in citizenship determination based on parentage.

• Those born after 1 January 1975 are Germans if the mother or father is a German citizen.
• Those born before 1 January 1975 could normally only claim German citizenship from the father and not the mother. Exceptions included cases where the parents were unmarried (in which case German mothers could pass on citizenship) or where the German mother applied for the child to be registered as German on or before 31 December 1977.
• Special rules exist for those born before 1 July 1993 if only the father is German and is not married to the mother. The father must acknowledge paternity before the child is 23, or acknowledge paternity and marry the mother and the child must declare himself or herself to be a German citizen.
• A child born in a foreign country will no longer receive German citizenship automatically by birth, if his/her German parent was born after 31 December 1999 in a foreign country and has his/her primary residence there. Exceptions are:

1. The child would be stateless.
2. The German parent registers the child's birth within one year of birth to the responsible German agency abroad.

• In case both parents are German citizens, German citizenship will not be passed on automatically, if both parents were born abroad after 31 December 1999 and have their primary residence outside of Germany. Exceptions are same as the above.
• Those born in Germany and adopted to a foreign country would need to contact their local German Consulate for clarification of German citizenship.

Persons who are Germans on the basis of descent from a German parent do not have to apply to retain German citizenship by age 23. If they acquire another citizenship at birth, they can usually continue to hold this.

Adoption

A child adopted by a German citizen becomes German national automatically if aged less than 18 on the date the application for adoption was made. So dual citizenship is granted.

Naturalisation as a German citizen

Naturalisation by entitlement

An individual who fulfils all of the following criteria has an entitlement to naturalise as a German citizen:

• he/she has been ordinarily resident in Germany for at least 8 years (this period can be reduced - see below)
• he/she has legal capacity or a legal representative
• confirms his/her present and past commitment to the free democratic constitutional system enshrined in the German Basic Law (or that he is presently committed to such principles and has departed from former support of ideas contrary to such principles)
• he/she is a European Union or Swiss citizen in possession of the appropriate residence permit which permits the free movement of persons, or he/she is a non-EU/Swiss citizen who has been granted a permanent right of residence
• he/she is able to support himself/herself without recourse to benefits
• he/she has not been sentenced for an unlawful act and is not subject to any court order imposing a measure of reform and prevention
• he/she possesses an adequate knowledge of German
• possesses knowledge of the legal system, the society and living conditions in the Federal Republic of Germany

An individual who does not have legal capacity is entitled to naturalise as a German citizen merely through ordinary residence in Germany for at least 8 years - he/she does not have to fulfil the other criteria (e.g. adequate command of the German language and ability to be self-supporting without recourse to benefits).

Applicants for naturalisation are normally expected to prove they have renounced their existing nationality, or will lose this automatically upon naturalisation. An exception applies to those unable to give up their nationality easily (such as refugees). A further exception applies to citizens of Switzerland and the European Union member states.

An individual who is entitled to naturalise as a German citizen can also apply for his/her spouse and minor children to be naturalised at the same time (his/her spouse and minor children need not have ordinarily resided in Germany for at least 8 years).

Exceptions to the normal residence requirements include:

• persons who have completed an integration course may have the residence requirement reduced to 7 years
• If a person shows that he/she is especially well integrated and has a higher level of command of the German language than the basic requirement for the German citizenship may have the residence requirement reduced to 6 years
• The spouse of a German citizen may be naturalised after 3 years of continual residency in Germany. The marriage must have persisted for at least 2 years.
• refugees and stateless persons may be able to apply after 6 years of continual residency
• former German citizens

Naturalisation by discretion

An individual who is ordinarily resident outside may be naturalised as a German citizen if he/she can demonstrate sufficient ties with Germany which justify his/her naturalisation.

Victims of Nazi persecution

Some people who lost German citizenship under the Nazi regime may be eligible for naturalisation without requiring residence in Germany or renunciation of their existing citizenship. Children and grandchildren of such persons may also be eligible for German citizenship.

German-born children

Under transitional arrangements in the 1999 reforms (effective 1 January 2000), children who were born in Germany in 1990 or later, and would have been German had the law change been in force at the time, were entitled to be naturalised as German citizens.

• An application for naturalisation was required by 31 December 2000.
• The child was required to apply for retention of German citizenship by age 23 and normally show that no other foreign citizenship was held at that time.

Naturalization statistics

From 1995 to 2004, 1,278,424 foreigners have obtained German citizenship by naturalization. This means, that about 1.5 % of the total German population had been naturalized during that period.

Right of return

Main article: Aussiedler

Those who are descendents of a German may claim German citizenship under Article 116 of the Basic Law for the Federal Republic of Germany.

Loss of German citizenship

German citizenship is automatically lost when a German citizen voluntarily acquires the citizenship of another country. To this there are two exceptions:

1. When the German citizen acquires a nationality from within the European Union, Switzerland, or another country with which Germany has a corresponding treaty.
2. When permission to obtain a foreign citizenship has been applied for and granted in advance of foreign naturalisation. A so-called permit to retain German citizenship must be obtained prior to naturalization. Failure to obtain a permit to retain German citizenship prior to naturalization results in the individual automatically losing German citizenship upon becoming a naturalized citizen of another country.

Other cases where German citizenship can be lost include:

• Persons acquiring German citizenship on the basis of birth in Germany (without a German parent) lose German citizenship automatically at age 23 if they have not successfully applied to retain German citizenship. If it is desired to maintain a foreign citizenship, application must be made by age 21.
• A German citizen who voluntarily serves in a foreign army (over and above compulsory military service) from 1 January 2000 may lose German citizenship unless permission is obtained from the German government. From 6 July 2011, the permission to serve above compulsory military service in the Israel Defense Forces is automaticlly given.
• A German child adopted by foreign parents, where the child automatically acquires the nationality of the adoptive parents under the law of the adoptive parents' country. (For example, a German child adopted by Americans prior to 27 February 2001—the effective date of the U.S. Child Citizenship Act of 2000—would not have automatically lost his/her German citizenship, because the child did not automatically acquire United States citizenship by virtue of having been adopted by U.S. citizens.) An exception applies where legal ties to the German parent are maintained.

Dual citizenship

Allowed under following circumstances:

• If he/she is an EU or Swiss citizen during naturalization.
• If he/she is a refugee and holds a 1951 travel document during naturalization.
• where a child born to German parents acquires another citizenship at birth (e.g. based on place of birth, or descent from one parent)
• where a naturalized German citizen, or a child born to non-German parents (non-EU or Swiss) in Germany, request and obtain a permission to keep his foreign nationality.
• where a German citizen acquires a foreign nationality with the permission of the German government (e.g. existing relative ties or property in Germany or in the other country or if the occupation abroad requires domestic citizenship for execution)
