Losing German citizenship living abroad is a genuine legal risk in certain situations — but it is far less common today than it was under earlier versions of German nationality law. The risk of losing German citizenship living abroad arises primarily through voluntary naturalisation in another country without prior permission. Understanding when losing German citizenship living abroad occurs — and when it does not — is essential for any German national residing outside Germany.
Losing German Citizenship Living Abroad — When It Can Happen
Losing German citizenship living abroad does not occur simply through residence outside Germany. Extended periods of living abroad, across any number of years or generations, do not by themselves cause loss of German citizenship. The primary legal risk of losing German citizenship living abroad involves the voluntary acquisition of a foreign nationality.
Loss of German citizenship in an earlier generation can decide whether a citizenship claim is still viable today. The key issues often include foreign naturalisation, residence abroad, marriage, historical loss rules, and whether German citizenship still existed when the next generation was born.
You may submit a short outline of your family background for an initial status review. If the matter appears suitable, I will invite you to a short introductory call free of charge. A written citizenship status review can then be requested as the next step where a structured legal assessment is appropriate.

Losing German Citizenship Living Abroad Through Voluntary Naturalisation
The most significant cause of losing German citizenship living abroad is voluntary naturalisation in another country. Under German nationality law, a German citizen who voluntarily acquires a foreign nationality generally loses German citizenship automatically at the moment of naturalisation — unless prior permission has been obtained from the competent German authority before the naturalisation takes place.
The permission requirement — Beibehaltungsgenehmigung
Since 2000, German citizens who wish to naturalise in another country without losing German citizenship can apply for a Beibehaltungsgenehmigung — a formal permission to retain German citizenship alongside the newly acquired foreign nationality. This application must be made and decided before the foreign naturalisation takes place. If permission is granted, losing German citizenship living abroad through naturalisation is avoided.
If no application was made, or if permission was refused, acquiring a foreign nationality results in automatic loss of German citizenship at the moment of naturalisation. This is the most common mechanism by which losing German citizenship living abroad occurs among members of the German diaspora today.
EU and Swiss nationals — an important exception
German citizens who naturalise as citizens of another EU member state or Switzerland are generally exempt from the permission requirement. In these cases, losing German citizenship living abroad does not occur — German citizenship is retained automatically alongside the newly acquired EU or Swiss nationality.
Losing German Citizenship Living Abroad — The 2024 Reforms
Germany significantly liberalised its approach to dual citizenship through reforms that came into force in 2024. These reforms now allow German citizens to hold multiple nationalities in most circumstances without the risk of losing German citizenship living abroad through naturalisation.
However, the 2024 reforms apply prospectively. For individuals who naturalised in another country before the reforms came into force without obtaining prior permission, the question of whether losing German citizenship living abroad occurred remains governed by the law as it stood at the time of naturalisation. Further detail on the current dual citizenship rules is available in our articles on dual citizenship Germany USA and dual citizenship Germany UK.
Losing German Citizenship Living Abroad Through Birth Registration Failure
A specific provision of German nationality law creates a risk of losing German citizenship living abroad across generations. Under Section 4(4) of the German Nationality Act, a child born abroad to a German parent who was also born abroad after 31 December 1999 does not automatically acquire German citizenship at birth — unless the child would otherwise be stateless, or unless the German parent registers the birth with the competent German authority within one year.
This provision means that losing German citizenship living abroad can occur not through any active loss event but through failure to register a birth within the required timeframe. German citizens living abroad with children born outside Germany should be aware of this registration requirement and ensure compliance within the one-year period.
Historical Causes of Losing German Citizenship Living Abroad
Under earlier versions of German nationality law, losing German citizenship living abroad could occur in a wider range of situations. Voluntary service in a foreign military, certain formal acts of renunciation, and other events could cause loss of German citizenship under provisions that are no longer in force today.
These historical loss provisions are particularly relevant for families researching citizenship by descent, where an ancestor living abroad may have lost German citizenship under rules that applied decades ago. The timing of any loss event relative to the birth of the next generation is the decisive factor in assessing whether citizenship was transmitted to later generations. A detailed explanation of historical loss situations is available in our article on whether a family may have lost German citizenship.
When Living Abroad Does Not Cause Losing German Citizenship
Losing German citizenship living abroad does not occur through residence outside Germany regardless of duration, holding a foreign permanent residence permit, working for a foreign employer or government, marrying a non-German national, or children growing up abroad and attending foreign schools. The risk of losing German citizenship living abroad is specific to voluntary naturalisation without prior permission and to the birth registration requirement for second-generation Germans born abroad.
What to Do If You Are Concerned About Losing German Citizenship Living Abroad
If you are concerned that you may have been at risk of losing German citizenship living abroad — whether through naturalisation, failure to register a birth, or another event — the first step is a structured legal assessment of your specific situation. This assessment identifies whether loss occurred, under which provision, and whether any remedial options are available.
In some cases, what appears to be a situation involving losing German citizenship living abroad turns out on closer examination not to have caused loss under the applicable rules. In others, loss did occur but remedial provisions or naturalisation pathways may be available. A legal assessment provides the clarity needed to determine the correct position.
Frequently Asked Questions
Does living abroad for many years cause losing German citizenship?
No. Losing German citizenship living abroad does not occur through residence outside Germany, regardless of how long you have lived abroad. The primary risk arises from voluntary naturalisation in another country without prior permission — not from residence alone.
I naturalised in the United States — did losing German citizenship living abroad occur automatically?
If you voluntarily naturalised as a US citizen without having obtained prior permission from the competent German authority, losing German citizenship living abroad occurred automatically at the time of naturalisation under the law then in force. Whether any remedial options exist depends on the specific circumstances and timing of the naturalisation.
Can losing German citizenship living abroad be reversed?
In some cases, yes. Specific remedial provisions exist for certain groups, and naturalisation in Germany remains an option for those who meet the applicable requirements. Whether reversal is possible depends on the specific circumstances of the loss. A legal assessment will identify which options are available.
My child was born abroad — is there a risk of losing German citizenship living abroad for them?
If you are a German citizen and your child was born abroad, your child generally acquired German citizenship at birth. However, if you yourself were also born abroad after 31 December 1999, your child may not have acquired German citizenship automatically — and registration within one year of birth may have been required. If that registration was not made, a legal assessment is advisable to determine the position.
Does the 2024 reform mean losing German citizenship living abroad no longer applies?
The 2024 reform significantly reduced the risk of losing German citizenship living abroad through naturalisation going forward. However, the reform applies prospectively — it does not automatically restore citizenship that was lost before the reform came into force. Prior naturalisations are assessed under the law that applied at the time.
What is the first step?
If you are unsure whether your family lost German citizenship at some point, the next step should usually be a structured review of the family line before collecting further certified documents or preparing an application. The decisive issues may include the ancestor’s original German citizenship, the timing of any foreign naturalisation, births in the next generation, marriage and legitimacy questions, historical loss rules, and the documents available to prove or clarify the chain.
You may first submit a short outline of your family background for an initial status review. If the matter appears suitable, I will invite you to a short introductory call free of charge. Where a written citizenship status review is appropriate, it can clarify whether German citizenship may have been lost, whether the family line can still support a claim, and which procedural route should be followed before filing.
