Dual nationality in Luxembourg
Becoming Luxembourgish does not mean giving up who you already are. Since 2009, Luxembourg has allowed dual nationality, so you can hold a Luxembourg passport alongside your current one. The catch sits elsewhere: your country of origin may have its own rules, and that is the part worth checking before you start.

What dual nationality in Luxembourg actually means
Dual nationality (sometimes called multiple nationality) means a person legally holds the citizenship of two or more countries at once. In practice, you keep all the rights and duties that come with each one. A 2009 reform of Luxembourg's nationality law opened this door, and the principle has held since: on the Luxembourg side, acquiring citizenship here does not require you to renounce another nationality.
This matters for the many people who build a life in the Grand Duchy without wanting to cut ties to their roots. You can become Luxembourgish, vote in national elections, travel on a Luxembourg passport, and still keep the nationality you were born with. For families that move across borders, that continuity carries real weight.
The Luxembourg side is clear; your home country may not be
Here is the distinction that trips people up. Luxembourg will not ask you to renounce anything. Your country of origin, however, sets its own terms, and those terms vary widely:
- Some countries fully accept dual nationality and do nothing when you naturalise elsewhere.
- Some forbid it outright and treat acquiring a new citizenship as grounds for losing your original one.
- Some trigger automatic loss of your first nationality the moment you take on another, often without any notice.
- Some allow it but require a declaration, a fee, or formal permission first.
Because the rule lives on the other side of the border, the answer depends entirely on your nationality of origin. Two colleagues sitting in the same Luxembourg office can face completely different outcomes simply because they hold different passports. Checking this early, before you file anything, is the single most useful step you can take.
Why the dual nationality question deserves real attention
Getting this wrong can be costly. If your home country strips your original nationality when you naturalise, you could lose property rights, pension entitlements, the ability to inherit, or even the right to enter that country without a visa. Some people only discover the consequence years later, when they try to renew a document that no longer exists for them.
None of this means dual nationality is risky in Luxembourg. It means the homework belongs on your side of the file. A clear answer up front lets you weigh the trade-offs calmly and decide with full information rather than hoping for the best.

How dual nationality connects to naturalisation
Dual nationality and naturalisation are two sides of the same decision. Naturalisation is the legal route to becoming Luxembourgish, usually through residence and a language requirement. Dual nationality is simply the fact that, once you complete it, you can keep your previous citizenship on the Luxembourg side. You can read the full conditions on our naturalisation in Luxembourg page.
For people who arrived on a work route, citizenship often sits at the end of a longer path that started with a work permit or an EU Blue Card. Each stage has its own rules, and the dual nationality question becomes concrete only when naturalisation is on the table.

FAQ
Does Luxembourg allow dual nationality?+
Luxembourg allows dual nationality and has done so since the 2009 reform of its nationality law. On the Luxembourg side, becoming a citizen here does not require you to renounce any nationality you already hold, so you can keep your original passport alongside a Luxembourg one.
Will I have to give up my original nationality to become Luxembourgish?+
You will not have to give up your original nationality on the Luxembourg side, because Luxembourg permits multiple nationality. The real question is whether your country of origin allows it, since some states forbid dual nationality or strip your first citizenship when you naturalise abroad.
How do I know if my home country permits dual nationality?+
Whether your home country permits dual nationality depends entirely on its own laws, which range from full acceptance to automatic loss of your original citizenship. We help you check your specific country of origin before you file anything, so you understand the consequences in advance.
What happens if my country of origin forbids dual nationality?+
If your country of origin forbids dual nationality, naturalising in Luxembourg could trigger the loss of your original citizenship, sometimes automatically. That can affect property, inheritance, pensions, and visa-free entry, which is why verifying the rule up front matters so much.
How is dual nationality linked to naturalisation in Luxembourg?+
Dual nationality is linked to naturalisation because naturalisation is the legal process of becoming Luxembourgish, while dual nationality is your ability to keep a previous citizenship once you complete it. You can see the conditions on our naturalisation in Luxembourg page.
