Are you ready to be a Luxembourgish citizen? Know what lies ahead in the residency test and the steps to take to acquire citizenship in Luxembourg.

A third-party country national who can prove lawful uninterrupted residence on Luxembourg territory of at least seven years immediately prior to submitting the application can apply for the status of long-term resident from the Ministry of Foreign Affairs. Here’s more of what you need to know.

To acquire Luxembourg nationality by naturalization, there are some conditions, including the following:

  • Be 18 years of age or older at the time of application.
  • Have legally lived in Luxembourg for seven consecutive years.
  • Pass an oral test in Luxembourgish.
  • Attend three civic instruction classes
  • Meet integrity requirements.

The oral/language Luxembourgish test

The language test includes oral expression and language comprehension. Interested in taking Luxembourgish lessons? Read even more in our guide on learning languages in Luxembourg.

The level of Luxembourgish oral expression given during the test corresponds to level A2 of the Common European Framework of Reference for languages in oral expression and language interaction. This is well beyond knowing just the basic Luxembourgish phrases; to pass, you must be capable of introducing yourself, speaking in simple terms about family, other people, living conditions profession and all-around daily life. You should be able to describe and compare people, things and activities in a simple manner. The test is with another person, with an interview on a given subject and a description of a visual aid. It generally lasts for 10 minutes.

The oral comprehension level of expectations is similar to B1 of the Common European Framework of Reference for languages in oral comprehension. To pass, it is important to understand the essential points and standard language about familiar subjects. The oral comprehension test lasts for 25 minutes and has three listening exercises as well as a questionnaire. To pass the language test, you must gain at least half the points in each of expression and comprehension.

Exempt from the test

Applicants can be exempt from the language test if they complete at least seven years of schooling in Luxembourg. You will have to submit your school and department certificates such as certified copies of school reports. You can also be exempt from the test if you have received a Luxembourg residence permit before 31 December 1984, and have remained a resident since (with evidence).

Civic instruction sessions

As a basis to know a foundational background on Luxembourg culture, it is necessary to attend three civic instruction sessions. Sessions are during evenings or on Saturday mornings. They are free of charge and taught in Luxemburgish, French, German, English, or Portuguese. Instructors award certificates of participation at the end; in fact, no tests are necessary. Two specific sessions are compulsory, however: “The fundamental rights of citizens and public life” and “Luxembourg state institutions”. The third session may be chosen from a list of other subjects that suit your interest, however.

Exempt from the sessions

You can be exempt from these instructional sessions if you have completed at least seven years of schooling in Luxembourg and, like the oral tests, can submit proof via certified school certificates of primary and secondary school enrollment. Also like the oral exam, those who have had a residence permit in Luxembourg before 31 December 1984 and have lived here since are exempt.

Condition of integrity

This condition basically means one must have a clean and honest record before being a long-term resident or citizen of Luxembourg. Naturalization is refused to an applicant who has made false statements or hidden important factors on the application, or who has been sentenced, in Luxembourg or another country, to a criminal penalty or imprisonment for a period of one year or more within the past 15 years.

Application process

A written application must be submitted to the authorities of your local commune of residence. An application form is available from the Ministry of Justice as well as from the website Documents must be translated into French or German by a sworn translator, and it is important to either submit the original of documents or provide a certified copy. All documents must have recent dates within the year. The Ministry of Justice may request other documents if it deems it necessary. All documents attached to the application must have a €4 stamp for civil status deeds and €2 for other documents.

Necessary documents

  • a birth certificate (and that of any minor children of the applicant);
  • accurate biographical information from the questionnaire model from the site and on this site (;
  • residence certificates covering the last seven years of living in Luxembourg. There certificates are available from your local municipal or commune of residence;
  • a certified authentic copy of the passport;
  • police record(s) covering the last 15 years;
  • a pass certificate for the Luxemburgish language test;
  • a certificate of attendance of civic instruction classes.

While the application is under examination, you may not leave the country. This can be up to eight months, as the Minister of Justice gives a positive or negative response to the application within eight months from submission. Suspension might happen if more information is necessary or there are significant changes during the application. If the application is refused, you can appeal before the administrative court within three months from being notified.

Citizenship by birth

Lastly, the children of Luxembourg citizens are Luxembourg nationals – wherever in the world they are born. In return, children born in Luxembourg to non-Luxembourg parents can also claim Luxembourg nationality if one or more of their parents was also born in Luxembourg. A child adopted by a Luxembourg citizen is also entitled to full citizenship.
