Five Years, a Luxembourgish Oral Exam and a Twenty-Four-Hour Course - or an Option That Asks for None of Them

Answer

The general rule applies to you

No exception is recorded for citizens of Brazil on this topic. That is the answer, not a gap - everything below is the rule you get, unchanged.

147 exceptions recorded across 54 countries · none match Brazil to Luxembourg · Becoming a citizen

Naturalisation under article 14 of the Act of 8 March 2017 asks for three things of an adult: habitual residence and lawful stay in Luxembourg for at least five years, the last of them uninterrupted; a pass in the Luxembourgish-language evaluation examination; and attendance at, or a pass in, the course "Vivre ensemble au Grand-Duché de Luxembourg". The language examination is set in Luxembourgish, not in French or German, and it is oral on both sides - speaking at level A2 of the Common European Framework and listening at B1 - with a weak speaking mark able to be carried by the listening one. The course runs twenty-four hours across three modules. Beside naturalisation the Act keeps a second door, option, with ten separate openings, and two of them ask for neither residence nor language: descent from a Luxembourgish parent or grandparent, and voluntary military service. A third, for someone resident twenty years, replaces the examination with a twenty-four-hour language course.

At a glance

Residence for naturalisation
Five years, the last one uninterrupted

Article 14(1) point 1 of the Act of 8 March 2017.

Language of the examination
Luxembourgish

Article 14(1) point 2, which requires the certificate of the examen d'évaluation de la langue luxembourgeoise and sends the reader to article 15 for what it contains.

Level required
A2 for speaking and B1 for listening, both oral

Article 15(1). Article 15(2) lets an arithmetic mean of the two marks carry a failed speaking paper.

Citizenship course
Twenty-four hours across three modules

Article 16(1), which splits them six hours on fundamental rights, twelve on state and communal institutions, six on history and European integration.

Exemption from the language examination
On a reasoned request, where physical or mental health makes learning the language impossible

Article 15(5), which requires a specialist's certificate and allows the minister to order a medical expert's report.

Option by a Luxembourgish parent or grandparent
Open to an adult, with no residence or language condition in the article

Article 23.

Option after twenty years' residence
A twenty-four-hour Luxembourgish language course instead of the examination

Article 28, in the wording given by the Act of 8 March 2023 on the consolidation's own attribution.

Option on marriage to a Luxembourger
The examination and the course, and three years of marriage where you do not live in Luxembourg

Article 25(1) and (2), which disapplies the three years for a spouse abroad on Luxembourgish public service or with an international organisation.

Recovery by a descendant of an ancestor Luxembourgish on 1 January 1900
The declaration had to be made by 31 December 2025, and the certification applied for by 31 December 2018

Article 89(1) of the Act of 8 March 2017, read in the consolidation applicable from 24 December 2024. Both deadlines are stated to apply on pain of the procedure being inadmissible.

Dual nationality
Not addressed as a bar anywhere in the Act's conditions for naturalisation, option or recovery

Articles 14, 23 to 32 and 39 set out those conditions and none of them requires renunciation; chapter 4 deals with loss separately.

Requirements

  • Five years of habitual residence and lawful stay, the last year uninterrupted
  • A pass certificate in the Luxembourgish-language evaluation examination
  • Attendance at, or a pass in, the "Vivre ensemble au Grand-Duché de Luxembourg" course
  • No criminal conviction of the kind article 14(2) point 3 describes

Country-level policy

Legislation Is Written in French, Administration Answers in Three Languages, and Naturalisation Is Tested in the One Nothing Is Legislated In

The Act of 24 February 1984 settles which language does what, and the answers do not line up the way a newcomer expects. The national language is Luxembourgish. Legislative acts and their implementing regulations are drafted in French, and where a translation accompanies them only the French text is authentic. In administrative, contentious and judicial matters French, German and Luxembourgish may all be used, and where a request is written in one of the three the administration must reply in that language so far as it can. What follows is concrete. The immigration Act, the nationality Act and the resources regulation are quoted in French, because French is the language they are law in. The tax residence test is quoted in German, because the 1934 statute that defines it has never been rewritten. And naturalisation is tested in Luxembourgish, which is neither.

What applies to you

Nothing changes for a citizen of Brazil

We have no rule recorded that treats your citizenship differently here, so the general rule above is the one that applies to you. That is an answer, not a gap.

What the law says

Two requirements inside one point: habitual residence and lawful stay, and the last year unbroken.

Luxembourg's official legal publisher, run by the Service central de législation. It issues the Journal officiel and, separately, textes coordonnés. Everything is addressed by ELI, and the address that matters is on the data host rather than the site: legilux.public.lu is an Angular single-page application that answers every address with the same 2,118-byte shell, while data.legilux.public.lu serves the documents. The live forms are data.legilux.public.lu/eli/<type>/<yyyy>/<mm>/<dd>/<id>/jo/fr/{html,pdf} for an act as published and .../consolide/<YYYYMMDD>/fr/{html,pdf} for a consolidation, where the date must be an exact consolidation date - any other date answers 404. Codes are addressed differently again, as /eli/etat/leg/code/<name>/<YYYYMMDD>/fr/pdf. The same host answers an Accept: application/rdf+xml request for any ELI with the record's metadata, and there is a SPARQL endpoint at data.legilux.public.lu/sparqlendpoint which is how a consolidation date is found rather than guessed: ?v jolux:isMemberOf <work ELI> ; jolux:dateApplicability ?d returns every consolidation of an act.

Standing: Maintains the text in force

Cannot be cited for: The consolidations are documentary. The Journal officiel as published is what has legal force, and the Code de la sécurité sociale prints that on its own notes page. The two manifestations of one consolidation are not the same document: the HTML carries the change markers and the amending-act headings - 'Art. 78. (L du 21 avril 2023)' - and breaks sentences with marker digits like '145 > quinze heures 145 <', while the PDF prints clean article text and drops both the markers and the headings. A quotation has to be taken from whichever one the sentence survives in. The consolidations also carry defects of their own: article 33 of the Act of 29 August 2008 is printed twice over in both manifestations, once as the original single sentence and once again as paragraph (1) with the same words. It cannot be cited for the income tax Act at all - it holds consolidation metadata for the Act of 4 December 1967 up to 1 February 2026 but serves no document for any consolidation after 2011, so the only current coordinated text of it is the tax administration's. Code recueils are PDF-only, and two of them set the publisher's own apparatus inside the text column: the Code de la sécurité sociale prints source references like 'L. 27.7.92' mid-sentence, and the Code de la route prints case-law annotations frozen at 2 September 2013 alongside articles consolidated to 2026. The Legilux record of the loi d'adaptation fiscale of 16 October 1934 tags its expression as French while the text it serves is German from beginning to end.

The Legilux record of the loi d'adaptation fiscale of 16 October 1934 tags its expression as French while the text it serves is German from beginning to end.

About this source

Luxembourg's official legal publisher, run by the Service central de législation. It issues the Journal officiel and, separately, textes coordonnés. Everything is addressed by ELI, and the address that matters is on the data host rather than the site: legilux.public.lu is an Angular single-page application that answers every address with the same 2,118-byte shell, while data.legilux.public.lu serves the documents. The live forms are data.legilux.public.lu/eli/<type>/<yyyy>/<mm>/<dd>/<id>/jo/fr/{html,pdf} for an act as published and .../consolide/<YYYYMMDD>/fr/{html,pdf} for a consolidation, where the date must be an exact consolidation date - any other date answers 404. Codes are addressed differently again, as /eli/etat/leg/code/<name>/<YYYYMMDD>/fr/pdf. The same host answers an Accept: application/rdf+xml request for any ELI with the record's metadata, and there is a SPARQL endpoint at data.legilux.public.lu/sparqlendpoint which is how a consolidation date is found rather than guessed: ?v jolux:isMemberOf <work ELI> ; jolux:dateApplicability ?d returns every consolidation of an act.

Standing: Maintains the text in force

Cannot be cited for: The consolidations are documentary. The Journal officiel as published is what has legal force, and the Code de la sécurité sociale prints that on its own notes page. The two manifestations of one consolidation are not the same document: the HTML carries the change markers and the amending-act headings - 'Art. 78. (L du 21 avril 2023)' - and breaks sentences with marker digits like '145 > quinze heures 145 <', while the PDF prints clean article text and drops both the markers and the headings. A quotation has to be taken from whichever one the sentence survives in. The consolidations also carry defects of their own: article 33 of the Act of 29 August 2008 is printed twice over in both manifestations, once as the original single sentence and once again as paragraph (1) with the same words.

Known to be out of date. The consolidation read here is applicable from 24 December 2024. This deadline has been moved by amending Acts at least three times; no Act extending it beyond 31 December 2025 was read, and Legilux publishes no later consolidation of this Act.

Practical notes

The Act makes the registrar, not the minister, the person who takes an option or recovery declaration, and article 33 lists the three grounds on which the registrar refuses to record one.

Option is the larger door. Articles 23 to 32 open it on descent, on being the parent of a Luxembourgish minor, on marriage, on birth in Luxembourg from the age of twelve, on seven years of Luxembourgish schooling, on twenty years' residence, on completion of the integration contract, on arrival before eighteen, on statelessness or international protection, and on voluntary military service.

Nothing in the conditions read here requires giving up another nationality. That is a statement about articles 14, 23 to 32 and 39 and about chapter 4 on loss, not a survey of every provision in the Act.

Recovery under article 39 is open to anyone who once held the nationality and has no residence or language condition. The wider route in article 89, for a descendant of an ancestor Luxembourgish on 1 January 1900, is a transitional provision with two deadlines, and the later one in the text read here was 31 December 2025.
