German Citizenship by Descent for Americans

The 19th-Century Emigrant's Descendant

Between 1820 and 1914, more than five million Germans crossed the Atlantic. They came from Bavaria, Baden, Württemberg, Hessen, the Palatinate, Prussia, Mecklenburg and Silesia. Some were Forty-Eighters fleeing the failed 1848 revolutions; some were Palatines escaping crop failure; many were young men avoiding conscription in the wars of German unification; others were.

If you descend from these emigrants, three questions will decide whether German nationality travelled with them and reached you:

• When exactly did your ancestor depart, and did they become a naturalised American citizen? Under the Prussian law of 1842 and the North German Confederation law of 1870, which became the Reich and Nationality Act, RuStAG, in 1913, a German who stayed abroad continuously for ten years without registering with a German consulate lost citizenship automatically. This is the notorious “ten-year rule” (§ 21 of the 1870 law). Voluntary naturalisation as a US citizen also broke the chain.
• Was the line of succession unbroken through legitimate births — or through the male line only, until 1975? German nationality law before 1 January 1975 passed citizenship through the father in legitimate births and through the mother only in births out of wedlock. A German great-grandmother who married a non-German man and had children with him before 1975 did not pass German citizenship to those children under the old law. This gap is capable of being rectified; see § 5 StAG Below.
• Did any intermediate ancestor commit an act that severed nationality? Serving in a foreign military without permission, voluntarily accepting foreign citizenship before the 2024 reform, or, in older cases, marrying a foreign man before 1953 could all break the chain.

If the ancestral chain is intact, the current-day descendant is not “becoming” German — they already are German by descent under § 4 StAG, or ius sanguinis. What they need is a Nationality card, a certificate of citizenship, from the BVA.Read our full guide: German Citizenship by Descent – Complete Pillar Guide.

If the chain broke, all is not necessarily lost. Two provisions can restore it: § 5 StAG declaration of acquisition for gender-discrimination cases, or § 14 StAG discretionary naturalisation from abroad For applicants with a demonstrable connection to Germany.

The War Bride's Grandchild

Between 1945 and 1955, roughly 20,000 German women married American servicemen stationed in occupied Germany. They followed their husbands to Fort Bragg, Fort Hood, Long Beach, and hundreds of smaller US posts, raising American children who often grew up knowing very little about their Oma's hometown.

For decades, the children of those marriages were told they had no claim to German citizenship. German law before 1975 did not pass citizenship through the mother to children born in wedlock. A child born in 1952 in Kansas to a US Army sergeant and a Munich-born mother inherited only the father's US citizenship in the eyes of the German state.

The Federal Constitutional Court eventually held this rule unconstitutional, and the legislature responded with § 5 of the Citizenship Act (StAG) — the Explanation acquisition, or acquisition by declaration. In its current form, after the 2021 reform, § 5 StAG allows descendants who were denied citizenship purely because of pre-1975 gender discrimination to declare their German nationality and receive it. Their own children benefit derivatively.

The § 5 StAG route is the most common way for third and fourth-generation Americans to acquire German citizenship. It covers not only the scenario of "war brides" but also earlier cases, such as a German great-grandmother in 1905 who married a Wisconsin farmer and whose line of descent was only broken because German law at the time did not recognise transmission through the mother.

The Refugee's Descendant — Article 116(2) of the Basic Law

Between 1933 and 1945, the Nazi regime stripped German citizenship from Jews, political opponents, Roma and Sinti, and other persecuted groups – sometimes by individual decree, sometimes by the 11th Ordinance to the Reich Citizenship Law of November 1941, which denationalised every Jew who left the Reich. Many of these refugees reached the United States. They settled in New York, Los Angeles, Chicago, Miami; they raised American children; they rebuilt lives that had been erased.

Article 116, paragraph 2 of the German Basic Law grants their descendants a legal right to have that stolen citizenship restored — not as a favour, not as discretionary naturalisation, but as reparation. Since the 2021 amendmentFourth Act amending the Nationality Act), the scope is broader than ever:

• Direct descendants of persecuted Germans – children, grandchildren, great-grandchildren – can apply.
• Both bloodlines qualify, regardless of gender or whether the persecuted ancestor was the mother, father, grandmother or grandfather.
• Applicants may retain their US citizenship. This is not a discretionary favour; it is a right rooted in Germany's post-war constitutional order.

For applicants whose ancestor fled persecution before formal denationalisation, leaving the ancestor technically still German on paper at the time of emigration, or in other constellations that fall just outside Art. 116(2), the fallback is § Section 15 StAG — a broader reparation clause added in 2021 to close historical gaps. Together, Art. 116(2) GG and § 15 StAG now cover almost every scenario of persecution that a German-Jewish, German-Sinti, or German-political-refugee family in the United States might face.
