German Citizenship — who qualifies

Sourced from German Embassy/Consulates & federal portals

Citizenship by descent (jus sanguinis)

At least one parent was a German citizen at the time of your birth. That’s the core rule. Nuances depend on birth date and parents’ marital status.
Older rules (pre-1975, recognition, etc.): If you were born before 1 Jan 1975 to married parents, citizenship generally passed through the father; later reforms and declarations partially fixed this for those previously excluded.
Children born abroad to Germans born abroad (after 31 Dec 1999): such children do not automatically acquire German citizenship unless the birth is registered (notified) within one year at a German mission.
Adoption: Being adopted as a minor by a German (on/after 1 Jan 1977) generally confers citizenship.
Proof of citizenship (if unsure): You can apply for a Certificate of Citizenship via the German mission; the Federal Office of Administration (BVA) makes the determination.

A child born in Germany can be German if one parent has lawful habitual residence in Germany for at least 5 years and holds an unlimited right of residence. (This was 8 years; reformed in 2024.)

Standard residence period: 5 years of lawful residence (reduced from 8 by the 2024 reform). A shortened period (as little as 3 years) is possible for “special integration achievements.”
Dual/multiple citizenship allowed for all newly naturalized persons since 27 June 2024 (no general renunciation requirement).
Core requirements typically include:
- Ability to support yourself (secured livelihood, i.e., no regular reliance on certain public benefits).
- German language skills at B1 CEFR level.
- Civics knowledge (Einbürgerungstest / “Life in Germany”).
- Clean record of serious crimes (certain offenses, incl. antisemitic/racist/xenophobic crimes, bar naturalization).
- Commitment to the free democratic constitutional order and Germany’s historical responsibility (spelled out by the federal government with the 2024 reform).
Where to apply: Inside Germany, your local nationality authority (Staatsangehörigkeitsbehörde). Outside Germany, the BVA handles many cases; German embassies/consulates advise, pre-check, and forward files.

Article 116(2) GG & §15 StAG: Victims who were deprived of citizenship between 1933–1945, and their descendants, can be (re)naturalized under facilitated rules. Applications abroad are typically lodged with German missions and decided by BVA.

Since 20 Aug 2021, people born after 23 May 1949 who would have been German but for past discriminatory rules may acquire citizenship by declaration (10-year window), including many cases of German mothers pre-1975 or German fathers in out-of-wedlock cases pre-1993. Declarations abroad can be filed at German missions or directly with the BVA.

No automatic citizenship by marriage since 1970. A spouse must naturalize and meet requirements. In practice, there is a facilitated route if you’ve been married at least 2 years and legally resident in Germany for ~3 years, subject to all other conditions.

As of 27 June 2024, multiple nationality is broadly permitted for new naturalizations; existing Germans who take another citizenship by application no longer lose German citizenship (old “retention permit” largely obsolete).

Inside Germany: your local nationality authority (city/district). Guidance on requirements is on BMI (Interior Ministry) and BAMF sites.
Outside Germany: the BVA is the competent nationality authority; German embassies/consulates (e.g., in the U.S.) are your front-line contacts for pre-assessment, appointments, and forwarding applications (e.g., certificates of citizenship, declarations).

Descent ≠ ancestry: Having German ancestors alone isn’t enough; the parent must have been German at your birth.
Birth-abroad registration rule: If the German parent was themself born abroad after 1999 and resides abroad, the next generation usually needs a timely birth registration to keep citizenship going.
Naturalization isn’t just time-based: You must meet language, civics, conduct, and livelihood
