Becoming a Luxembourg citizen

The acquisition of the Luxembourg citizenship by naturalisation confers abroad the status of Luxembourger with all the attached rights and duties.
Since the 1st of April 2017, a new law authorises the residents having been living in Luxembourg for at least 5 years to acquire the Luxembourg nationality by naturalisation under certain conditions. Furthermore, the applicant is not obliged to give up his nationality of origin owing to the principle of dual nationality.

Who is concerned by the Luxembourg naturalisation?

Gelle fra, LuxembourgThe new law of 2017 plans the automatic allocation of the Luxembourg nationality to any person being 18 years old and who was born in Luxembourg provided that:

  • They have been living in a regular way in Luxembourg for at least five consecutive years, just before their majority;
  • That one of their parents have lived in Luxembourg during at least twelve consecutive months immediately preceding the birth.

If these two conditions are gathered, it will be possible in the future for a child born in the Luxembourg to obtain the nationality from 12 years old via the “option procedure”.

NB: the acquisition of the Luxembourg nationality by the option is possible in 10 precise cases. In order to know those 10 cases go on the website of

The second generation “jus soli” applies in Luxembourg. A child born in Luxembourg whose one of the parents or adopting parents was also born in the Grand duchy, will automatically be provided with the Luxembourg nationality.

Period of residence

The period of residence planned by the new law of 2017 passes from 7 years to 5 years before the nationality can be asked for.

Test of language

The linguistic evaluation examination involves:

  • A test of oral expression focusing on level A2 (from the common European reference frame for the foreign languages);
  • A test of oral understanding focusing on level B1.

The candidate will have to participate in both of the tests. A system of compensation between the tests was introduced. The candidate has to obtain the average in the oral expression test to pass the language evaluation one. If he does not get the average to the oral test, his note can be compensated with the note obtained during the test of oral understanfing.

Registration fees for the examination and the Luxembourg language courses will be paid off by the State.

“Living together in the Grand-Duchy of Luxembourg” certificate

In the new law, the course of civics is replaced by the course “Living together in the Grand Duchy of Luxembourg” established by 3 modules for a total of 24 hours of lessons:

1. The fundamental rights of the citizens (6-hour module)
2. The Luxembourg State and municipal institutions (12-hour module)
3. The history of Luxembourg and the European integration (6-hour module).

In order to obtain the nationality or the naturalisation the certificate for the course “Living together in Luxembourg” is compulsory. It can be obtained by following the training or by passing an examination. For example, the people having already done a “Civics”training course and not having time to do the training course can direct enroll for the examination.

In brief, every person who satisfies the conditions to be naturalised, and who does not go into the field of the recovering of the Luxembourg nationality, can ask for the Luxembourg nationality under the following conditions:

  • Being major (more than 18 years old) at the time of the request
  • Having lived legally in Luxembourg for more than 5 years and at least for 1 year in a continuous way at the time of the deposit of the citizenship application
  • Meeting the requirements of good repute. That is the applicant will not have to have made false declarations, or hidden important facts or to have cheated in some way when applying for the citizenship. He will also have to not have been the object of any condemnation of a criminal punishment or a firm detention of a duration of 12 months or more, or a conditional sentence of 24 months or more.

Under certain conditions the expenses paid (with ceiling) for acquisition of the Luxembourg nationality can be reimbursed. The request must be made to the Ministry of Justice, Service of Indigeny.

Conditions to be able to ask to be a naturalised Luxembourg citizen

The candidate for the Luxembourg naturalisation will have to:

  • Have passed the spoken Luxembourg language evaluation test. The spoken Luxembourg language evaluation test is organised by the Institut National des Langues du Luxembourg. For the oral expression the required level is A2, which corresponds to a basic conversation: being capable of appearing, asking for directions, going shopping, asking about someone, etc. For the oral understanding, the expected level corresponds to B1: it is necessary to be capable of understanding the subjects of the daily life, at work, between friends, on the radio etc.
  • Have attended civics classes. The applicant will also have to have attended the “Living together in the Grand Duchy of Luxembourg” civics class or passed the examination focusing on the subjects taught in this course.

There is no examination, but a certificate recognising the participation is attributed to the participants.
  • The people who achieved at least 7 years of schooling within the framework of the Luxembourg State education, or who have had a residence permit since before the 31st of December 1984 and who have been living in Luxembourg since then are exempted from the evaluation of spoken Luxembourgish, and from the civics lessons.

The principle of dual nationality

Since the 1st of January 2009, it is possible to be granted the Luxembourg nationality, while keeping your nationality of origin. It is called the principle of dual nationality.

Be careful however, if Luxembourg accepts this principle, this is not the case in all the countries, and it is possible that the country of origin of the applicant for the Luxembourg nationality does not apply this principle. It is the responsibility of the candidate to verify with the authorities of which he already has the nationality.
