How to obtain citizenship in Luxembourg

As a member of the European Union and the Schengen Area, Luxembourg offers many advantages to its citizens: access to the EU job market, free movement within the EU, and a high standard of living. If you are interested in becoming a citizen of Luxembourg, there are several requirements that you need to be aware of.

For many years, the Luxembourg passport has been and is ranked one of the best in the world. The ranking is based on the number of countries that can be accessed visa-free by their holders. According to the Passport Ranking Index, the Luxembourg passport currently holds the 4th position globally, allowing citizens to visit 188 countries without a visa.

In this article, we will guide you through the process of obtaining citizenship in Luxembourg, from eligibility criteria to the application process and naturalization requirements. Whether you are a foreign resident, an EU citizen, or a non-EU national, there are a few ways to make your dream of becoming a Luxembourger a reality.

How Luxembourg citizenship differs from permanent residence

For non-citizens, obtaining permanent residence in Luxembourg can be a significant milestone in their journey toward settling down in the country. It grants them the right to stay and work in the country indefinitely and access certain social benefits. However, permanent residence is not the same as citizenship, and there are several crucial differences between the two statuses, the most important ones are the following:

  1. Right to vote and participate in elections

    Luxembourg citizens have the right to vote in national, local, and European elections, while permanent residents cannot vote or stand for election.

  2. Protection against deportation

    As a citizen, you have a higher level of protection against deportation, whereas permanent residents can still be deported in certain circumstances.

  3. Passport and access to social benefits

    Luxembourg citizenship provide access to a wider range of social benefits, including eligibility for certain government jobs and the ability to obtain a Luxembourg passport, which allows visa-free travel to many countries. On the other hand, permanent residents cannot have a Luxembourg passport and do not have access to all social benefits.

  4. Sense of identity and belonging

    Citizenship provides a stronger sense of identity and belonging to the country, which can be important for some individuals, while the permanent residence is more of a legal status.

Dual citizenship is recognized in Luxembourg. That means that if you become a citizen of Luxembourg, you can still maintain your original citizenship in your home country. However, it is essential to note that some countries do not recognize dual citizenship, so check with your home country's embassy or consulate to understand the implications of dual citizenship in your specific case.

Who can obtain Luxembourg citizenship and in what case

In Luxembourg, there are several ways to obtain citizenship for people of other nationalities: by naturalisation, by option, and by reclamation in case the individual previously had citizenship of the Grand Duchy.

In some cases, citizenship can be acquired automatically, without the need for an application, by operation of law. This applies to individuals born to a Luxembourgish parent or adopted by a Luxembourgish citizen – they receive citizenship automatically.

There are specific eligibility requirements that must be met before you can obtain Luxembourg citizenship in each case and these requirements vary depending on your personal situation. Luxembourgish nationality can be obtained by following one of the common procedures.

  1. Naturalization

    This is the most common method of obtaining citizenship for non-Luxembourgish individuals. It requires meeting certain eligibility criteria, such as language proficiency, length of residence in Luxembourg, and proof of integration into Luxembourgish society. The application process can take several months and involves various documents and interviews.

  2. Option declaration procedure

    This option is available to persons:

    • with a Luxembourg parent or grandparent;
    • whose minor child is a Luxembourger;
    • married to a Luxembourg citizen;
    • born in Luxembourg over 12 years old;
    • who have completed at least 7 years of schooling in Luxembourg;
    • of legal age who have lived in Luxembourg for more than 20 years;
    • who have fulfilled the commitments of the reception and integration contract;
    • of legal age who settled in Luxembourg before his/her 18th birthday;
    • with stateless, refugee, or subsidiary protection status;
    • who have been volunteer soldiers.

    This option allows the individual to claim Luxembourg citizenship without going through the naturalization process if they meet certain eligibility criteria and can provide the required documents.

  3. Reclamation procedure

    This option is available to individuals who lost their Luxembourgish citizenship due to certain circumstances, such as acquiring foreign citizenship or living outside of Luxembourg for an extended period. The individual can reclaim their Luxembourg citizenship by meeting certain eligibility criteria and going through the application process.

In the following text sections, we will focus on voluntary acquisition procedures. And explore who can obtain Luxembourg citizenship in each case, and which documents and procedures are required.
