Luxembourgish nationality can be acquired through naturalisation. Naturalisation confers upon the person concerned all the civil and political rights associated with being a Luxembourgish national. These rights do not have any retroactive effect.
The forms listed in the "Forms" section are to be submitted in person to the commune of residence, together with all other legally required documents.

- Autorisation de demander le bulletin n°2 du casier judiciaire
- Notice biographique - questionnaire pour la naturalisation, la déclaration d'option ou de recouvrement
Naturalisation is open to all adults, provided that:
- they have legally resided in Luxembourg for at least five years. The final year of residence immediately preceding the naturalisation application must have been uninterrupted;
- they have knowledge of the Luxembourgish language, as evidenced by a Luxembourgish language test pass certificate;
- they have taken the "Vivre ensemble au Grand-Duché de Luxembourg" course or passed the test covering the topics taught in this course.
Acquiring Luxembourgish nationality is subject to a condition of good repute. Consequently, Luxembourgish nationality is refused:
- if the applicant has made false statements, concealed important information or acted fraudulently during the naturalisation procedure; or
- if the applicant has received, in the Grand Duchy of Luxembourg or abroad:
- a criminal sentence or a custodial sentence of 12 months or more; or
- a suspended sentence of 24 months or more.
The naturalisation procedure is free of charge.
However, the preparation of certain documents to be produced as part of the naturalisation procedure may incur charges, the amount of which is set by the issuing authority. For example:
- Luxembourg communes may request the payment of a municipal tax in exchange for preparing copies of marital status records;
- foreign authorities may apply a charge for the issuance of marital status records or extracts from the criminal record.
Applying to the civil registrar for naturalisation
Applications for naturalisation are made to the civil registrar of the commune of the applicant's usual place of residence. The applicant must appear in person before the civil registrar. They may be accompanied by a person of their choice.
The naturalisation application must be signed by the applicant or their legal representative. Signature by proxy is not permitted.
If the legal conditions are met and the application contains all the necessary documentation, the civil registrar will record the naturalisation application. They will then send the file to the Ministry of Justice directly and without delay.
If the file submitted is incomplete, the civil registrar will request that the applicant produce the missing documents. If the documents are not submitted within a period of 3 months, the naturalisation application will not be considered.
Supporting documents to be submitted with the application
Applicants must submit the following documents to the civil registrar in support of their naturalisation application:
- a full copy of their birth certificate and, if necessary, that of their children aged under 18;
- a copy of their valid passport and, if applicable, that of their children aged under 18. If they do not have a passport, another identity or travel document may be provided;
- precise biographical details signed by the applicant or their legal representative. Applicants must:
- use the biographical questionnaire notice biographique;
- complete it honestly and in full;
- sign and date the biographical questionnaire;
- if applicable, provide an authorisation granting the Ministry of Justice the right to request the record no. 2 of the applicant's criminal record before the final naturalisation decision is made;
- if applicable, provide a copy of the foreign criminal record or a similar document issued by the competent public authority of the countries in which the applicant has lived from the age of 18 during the 15 years immediately preceding the initiation of the naturalisation procedure;
- a Luxembourgish language test pass certificate;
- a certificate confirming the applicant attended the "Vivre ensemble au Grand-Duché de Luxembourg" course or passed the exam covering the course;
- if applicable, authorisation of the judge supervising guardianship to initiate the naturalisation procedure;
- if applicable, a decision of the Minister authorising an exemption from submitting one or more of the required documents. This exemption can be obtained upon reasoned request from the Minister of Justice, who has sole authority to grant it.
If a required document has not been drafted in French, German or Luxembourgish, the applicant must submit it with a translation in one of these 3 languages. The translation must be performed by sworn translator or by a foreign public authority.
The civil registrar will request the issuance of the record no. 2 of the criminal record from the public prosecutor's office after having obtained the applicant's approval. Applicants are advised to send the authorisation form to the civil registrar approximately 15 days before going to the communal office to sign the naturalisation application. If applicants refuse to give this authorisation, the application will not be considered.
The civil registrar can refuse to record the application. In this case, an appeal against this decision can be made to the Minister of Justice within one month of notification of this refusal. If the appeal is rejected by the Minister, a reversal on appeal may be petitioned before the administrative tribunal.
The ministry may request that additional documents be provided when those supplied by the applicant are insufficient or unsuitable to be used as evidence that the conditions have been met.
Review of the application by the Ministry of Justice
Applications are reviewed by the Nationality Office of the Ministry of Justice.
After having obtained the applicant's approval, the Ministry of Justice will request the issuance of the record no. 2 of the criminal record from the public prosecutor's office. If applicants refuse to give this authorisation, the application will not be considered.
The Ministry of Justice may request that additional documents be provided if those supplied by the applicant are insufficient or unsuitable to be used as evidence that the conditions have been met.
Applications may be suspended in the event that the applicant is the subject of criminal proceedings in Luxembourg or abroad.
By ministerial order, the Minister of Justice will grant or reject naturalisation within a period of 8 months from submission of the naturalisation application. Naturalisation shall take effect on the date of the ministerial order.
As a rule, applicants are notified of this order by post.
Applicants may petition the administrative tribunal for a reversal on appeal of the decision to refuse to grant nationality within a period of 3 months of notification of this decision. The appeal must be lodged by a court lawyer.
