The 2024 reform of German nationality law was the most significant in a generation, and its dual-citizenship change reshaped the calculus for millions of people with German roots. But a 2025 course-correction then walked one piece of it back, and the result is a landscape that older articles describe incorrectly. Here is what actually changed, what survived, and what it means specifically if you are pursuing citizenship by descent.
What the 2024 law did
The Act to Modernise Nationality Law (StARModG) came into force on 27 June 2024. Its core changes were:
- Dual citizenship for all. Applicants no longer have to give up their existing nationality, and German citizens may acquire a foreign citizenship without losing their German one.
- No more retention permit. The old Beibehaltungsgenehmigung — the permission a German previously needed before taking another citizenship — is gone.
- End of the opt-out duty. Children born in Germany to foreign parents are no longer required to choose one citizenship at adulthood (the former Optionspflicht).
- Faster naturalisation. The standard residence requirement for naturalisation dropped from eight years to five.
Importantly, these provisions apply from the date the Act took effect and are not retroactive. They do not reverse citizenship losses that happened before 27 June 2024 — a point that matters enormously for descent claims and is explained in our broken-chain guide.
What changed again in 2025
The 2024 reform also introduced a three-year “fast-track” naturalisation for exceptionally well-integrated residents who met strict language and integration criteria. That fast-track proved politically contentious, and it was repealed; the change took effect on 30 October 2025, restoring a uniform five-year minimum for the standard route, with no transitional protection for applications still pending when the repeal landed.
Two things to keep straight, because this is where stale content misleads readers. First, the repeal touched only naturalisation by residence. Second, dual citizenship and the five-year route both survived. If you read an older article promising German citizenship after three years, it is out of date — but the dual-citizenship reform that matters most to ancestry applicants is fully intact.
Why this matters for descent claims
For people claiming citizenship through ancestry, dual nationality was usually preserved already — a §4 determination or an Article 116/§15 restoration did not force you to renounce your existing passport. What the 2024 reform removed was the fear and the edge cases: the worry that claiming German citizenship might somehow jeopardise your American, Canadian, British, Australian, or other nationality, and the awkward situations created by the old renunciation regime.
Today the position is clear and reassuring: pursuing a German passport by descent does not require giving up the one you already hold. For the large German-American and German-Canadian populations in particular, this removed the last major hesitation, and consular interest in descent claims has risen accordingly.
A word of caution: check your other country’s rules
Germany no longer restricts dual citizenship, but your other country might. Most major destinations for the German diaspora — the United States, Canada, Australia, the United Kingdom, Brazil, Argentina — permit dual citizenship, but rules differ and can change, and a few countries elsewhere still require renunciation. Confirm your own country’s current position before you act, because Germany’s permissiveness does not override another state’s restrictions.
Common questions
Did the 2024 law make my lapsed German line valid again?
No. The reform is not retroactive and does not revive a chain that broke before it took effect. If your §4 chain broke, look to §5 or Article 116/§15 instead.
Can I still get citizenship after three years anywhere?
Only spouses of German citizens have a three-year naturalisation route; the general three-year fast-track was repealed in October 2025. Descent claims are unaffected by any of this — they are not about residence at all.
Why Germany resisted dual citizenship for so long
For most of its postwar history, Germany treated single nationality as the norm and dual citizenship as an exception to be permitted only grudgingly. That philosophy is why so many twentieth-century emigrants lost their German citizenship the moment they naturalised abroad — and why so many family chains broke. The 2024 reform did not just change a rule; it reversed a long-standing principle, bringing Germany into line with most of its European neighbours and with the realities of a mobile, diaspora-connected world.
How your other country sees it
Because the descent question is settled on the German side, the practical issue for most applicants is their other country’s stance. In broad terms:
- United States, Canada, United Kingdom, Australia: all permit their citizens to hold another nationality, so acquiring German citizenship does not jeopardise these.
- Brazil and Argentina: both home to large German-descended populations, generally permit dual nationality.
- Some other states still require renunciation or restrict dual citizenship — check your specific country’s current rules.
Germany imposes no restriction, but it cannot waive another country’s, so the final word on whether you may hold both lies with your existing state of nationality.
What has not changed for descent
It bears repeating because the headlines focused on naturalisation: none of the 2024 or 2025 changes alter the descent rules themselves. The §4 chain analysis, the §5 declaration with its 2031 deadline, and the deadline-free Article 116/§15 restoration routes all operate exactly as before. What changed is the dual-citizenship backdrop against which they play out — and for the better.
I naturalised abroad years ago and lost my German citizenship. Does 2024 give it back?
No — the reform is not retroactive. A past loss stands. Depending on the circumstances, you might re-acquire through naturalisation or, if persecution was involved, through Article 116/§15; a fresh analysis is worth doing.
Protecting your dual status in practice
For descent applicants the dual-citizenship question is largely self-resolving, but a few habits avoid trouble: confirm in writing that your existing country permits dual nationality before you file; keep your current passport valid throughout the German process so you are never without a travel document; and, if you were ever previously required to renounce or were told you had lost a citizenship, get that history checked, because the rules that applied at the time may differ from today’s. None of this is onerous — it is simply making sure both passports remain firmly in hand.
If I get German citizenship, will the US (or my country) be told automatically?
There is no automatic cross-notification between Germany and your home country when you establish German citizenship by descent. What matters is whether your country permits dual nationality — the major diaspora destinations generally do — not whether a notice is sent.
Does becoming German change my obligations at home?
Acquiring German citizenship by descent does not, by itself, alter your existing citizenship or its obligations — you simply hold two. Specific consequences (voting, military service, tax filing) depend on the laws of each country you belong to, so check your home country’s rules for dual citizens rather than assuming German citizenship changes them.
