Immigration in Luxembourg: complete guide by nationality (2026)

Which immigration route applies to your nationality?

In Luxembourg, the immigration pathway depends first on nationality. EU, EEA and Swiss citizens move freely: free stay of up to 3 months; to settle, declaration of arrival at the commune (within 8 days of arrival), then registration (within 3 months).

Third-country nationals, by contrast, must obtain a D visa before entry, often after a labour market test through the ADEM (national employment agency), then a residence permit. Specific routes exist depending on the profile.

Criterion no. 1: your nationality

Before taking any step, ask yourself a single question: what is your nationality? The answer guides everything else.

EU/EEA/Swiss citizen: you benefit from freedom of movement. You may enter, stay for up to 3 months and look for a job without prior authorisation. The formalities are declaratory, not authorisation-based.

Third-country national: subject to exceptions (see the case of family members of an EU citizen), you must obtain a D visa before entering the territory. The principle is reversed: no visa, no lasting settlement.

Specific profile: certain statuses (highly qualified manager, transferred employee, investor, self-employed worker, student, family member) follow dedicated rules that may relax or supplement the general regime.

An important nuance: a third-country national who is a family member of an EU or Luxembourg citizen does not follow the standard 'third-country' pathway, but a separate regime, closer to freedom of movement (see Guichet.lu, family member of an EU citizen).

It depends in particular on your nationality, your family status and the purpose of your stay (work, studies, investment, family). If in doubt, check your exact situation on Guichet.lu.

Case 1: EU/EEA/Swiss citizens, freedom of movement

Your rights. As a citizen of the European Union, of the European Economic Area (Iceland, Liechtenstein, Norway) or of Switzerland, you benefit from the freedom of movement of persons enshrined in EU law and transposed into Luxembourg law. In practical terms: you may enter Luxembourg on simple presentation of a valid identity card or passport; you may stay there freely for up to 3 months with no formality other than the declaration of arrival; you may work, as an employee or as a self-employed person, without a work permit or a labour market test.

Formalities beyond 3 months. The right to stay for more than 3 months is not automatic: it requires carrying on an activity (as an employee or self-employed), having sufficient resources and health insurance (a self-sufficient 'inactive' person), studying, or being a family member of a person who meets one of these conditions. Two formalities follow one another, with the commune administration of the place of residence: the declaration of arrival, to be made within 8 days of arrival; then registration, within 3 months of arrival, the registration category (worker, self-employed person, person with sufficient resources, student, family member) determining the documents to be provided.

Usual documents. Valid identity card or passport; depending on the category: employment contract or certificate of employment, proof of registration with the Trade and Companies Register (RCS) for self-employed persons, proof of resources and health insurance for self-sufficient persons, certificate of enrolment for students. If your documents are not drafted in German, French or English, a certified translation by a sworn translator may be required. Official source: Guichet.lu, staying and/or working for more than 90 days as an EU citizen.

Case 2: third-country nationals, authorisation before entry

For a national of a country outside the EU/EEA/Switzerland (except in the particular case of family members of an EU citizen), the principle is strict: a D visa issued before entry into the territory is required (since 1 October 2026 it replaces the temporary residence authorisation). An application filed from within Luxembourg is in principle inadmissible.

Steps before arrival (employee example). First, the employer must declare the vacancy to the ADEM before publishing the job offer and before recruiting: this is the starting point of the labour market test, which is intended to verify that no candidate available locally (an EU national in particular) can fill the post. Where no suitable candidate is put forward at the end of a period of three weeks, the ADEM may issue a certificate authorising the employer to recruit a third-country national (it is valid for three months and cannot be extended, and its issue is accelerated for shortage occupations); certain highly qualified profiles are not subject to this test. Next, since 1 October 2026, the prospective employee applies for a long-stay visa (type D) at the embassy of Luxembourg or, failing that, of Belgium competent for their country of residence, whether or not they are subject to a visa requirement for a short stay; this visa replaces the former temporary residence authorisation.

Steps after arrival. The third-country national makes a declaration of arrival at the commune within the statutory period applicable to their status (the official pages indicate a period of 3 business days for several categories of third-country nationals); the D visa covers their stay while awaiting the issue of the permit, applied for from the General Directorate of Immigration. They undergo the medical check for foreign nationals (medical examination and tuberculosis screening), to be carried out as soon as possible. Finally, they obtain their biometric residence permit, often valid for one year for a first employed worker permit, renewable.

Role of the employer. The employer is a central player: it declares the vacancy to the ADEM, provides the employment contract and plays a key role in putting together the file. Recruiting without having complied with the vacancy declaration and obtained the authorisations exposes the company to penalties for employing nationals whose stay is irregular.

Case 3: specific routes

Several statuses are governed by dedicated rules that relax or supplement the general third-country regime. The table below gives the key points; each amount or threshold must be confirmed on Guichet.lu at the date of the application.

EU Blue Card: reserved for highly qualified profiles, it dispenses with the labour market test but requires a salary threshold set by ministerial regulation (EUR 65,652 gross per year for applications filed from 3 March 2026, compared with EUR 63,408 previously). Be sure to check the amount in force at the date of your application, as it is reviewed every year. Source: Guichet.lu, EU Blue Card.

Intra-corporate transfer (ICT): transposes Directive 2014/66/EU and makes it possible to transfer a manager, an expert or a trainee from a non-EU entity to an entity of the same group in Luxembourg. The duration of the permit depends on the category. Source: Guichet.lu, intra-corporate transfer (ICT).

Investor: several investment options exist, each subject to thresholds and to conditions for maintaining the investment, with the opinion of the Minister of the Economy (existing company or company to be created) or of the Minister of Finance (investment and management structure, deposit). This scheme, whose repeal is provided for by bill no. 8586 (scheduled for a vote in the Chamber of Deputies on 14 October 2026), remains applicable until the repealing law is published in the Official Journal (see our article on the investor residence permit). As the amounts are liable to change, refer to the official page. Source: Guichet.lu, third-country investor.

Self-employed worker / business founder: the viability of the project and good repute (honorabilité) are at the heart of the examination, with sector-specific authorisations where relevant. Source: Guichet.lu, self-employed worker.

Family reunification: conditions relating to resources (assessed by reference to the minimum social wage) and suitable housing, in order to bring over a family member of a non-EU resident. Source: Guichet.lu, family reunification. Our dedicated guide: family reunification in Luxembourg.

Student: enrolment cannot in principle be finalised without a prior D visa. Source: Guichet.lu, third-country student.

Working Holiday (Work and Travel): cultural exchange programme open to young nationals of partner countries, with a 12-month visa. The partner countries and age conditions are set by the agreements. Source: Guichet.lu, Working Holiday.

Legal framework and authorities

Luxembourg immigration law rests mainly on the amended law of 29 August 2008 on the free movement of persons and immigration, which repealed the 1972 law and transposes several European directives (EU Blue Card, intra-corporate transfer, students and researchers, family reunification). The coordinated text and the consolidated versions are published on Legilux: law of 29 August 2008.

Responsibilities are divided among the competent authorities: the General Directorate of Immigration (Ministry of Home Affairs) for residence authorisations, residence permits, family reunification and investors; the Ministry of Foreign and European Affairs, Defence, Development Cooperation and Foreign Trade (Passport, Visa and Legalisation Office) for diplomatic and consular missions and the issue of D visas; the ADEM (Employment Development Agency) for the vacancy declaration and the labour market test; the commune administrations for the declaration of arrival and the registration of EU citizens.

General conditions and costs

Several cross-cutting conditions determine the regularity of the pathway, whatever the status: the correct order of the steps (D visa before entry for third-country nationals), the labour market test for non-exempt employees from outside the EU, the salary threshold for the EU Blue Card, the resources and housing conditions for family reunification, the declaration of arrival within the deadlines, the medical check for third-country nationals, and the validity and renewal of the permit. The table of general conditions below summarises each requirement and the risk incurred.

Costs. The procedures generate costs: a chancery fee or charge for certain applications (for example, the processing of investor files or the issue of permits), visa fees, translation and legalisation costs and, where relevant, advisory fees. As the amounts are set by regulation and are liable to change, no fee schedule is reproduced here: refer to the Guichet.lu page for your procedure for the exact amount in force.

Timescales: theory and practice

EU citizens: quick commune formalities, often processed on the same day or within a few days. The declaration of arrival is due within 8 days, registration within 3 months.

Third-country employees: the timetable depends on the labour market test and the processing of the D visa. In practice, allow several weeks to several months depending on how complete the file is and the country of origin.

EU Blue Card / ICT: profiles exempt from the labour market test, and therefore often faster, but subject to processing by the General Directorate of Immigration.

Actual timescales depend in particular on how complete the file is, the country of residence, consular availability and the workload of the administrations. The indicative timescales shown on Guichet.lu are not a guarantee.

Legal risks and common mistakes

The risk matrix below lists the main pitfalls, from entry without prior authorisation to exceeding the authorised length of stay, with an example and a preventive measure for each. These risks can mostly be avoided by correctly characterising the pathway at the outset.

Common mistakes. Believing that a third-country national can 'come and see' and then regularise their situation on the spot, when the D visa must be requested before entry. Confusing the declaration of arrival (a commune formality) with the residence permit (issued by the General Directorate of Immigration). Forgetting the labour market test on the employer's side. Relying on an EU Blue Card salary threshold found on a blog, when the amount is revised every year. Neglecting sworn translations and the legalisation of civil status documents. Letting a permit expire without applying for renewal in time.

Three practical cases

EU citizen employee (French) recruited in Luxembourg City. She enters with her identity card, signs her contract, declares her arrival at the commune within 8 days, then registers as a worker within 3 months. No work permit, no ADEM test. A declaratory and quick process.

Non-EU manager (Indian) with an EU Blue Card. Their employer declares the post to the ADEM (highly qualified profiles are, however, exempt from the labour market test), the contract is for at least 6 months and the salary reaches the regulatory threshold in force. The manager applies for their D visa from abroad, enters Luxembourg, makes the declaration of arrival and undergoes the medical check, then receives their residence permit. Checking the up-to-date salary threshold is essential.

Non-EU business founder (Brazilian) wishing to start a self-employed activity. He prepares a viable project, demonstrates his good repute, obtains any sector-specific authorisations and applies for his D visa from abroad. After his entry, he completes the commune and medical formalities. The core of the file is the economic soundness of the project.

Decision tree: which route for your situation?

Are you an EU/EEA/Swiss citizen? If so, freedom of movement: free stay of up to 3 months; to settle, declaration of arrival (within 8 days of arrival) and registration (within 3 months). If not, go on to the next question.

Are you a family member of an EU or Luxembourg citizen? If so, the specific 'family member of an EU citizen' regime (close to freedom of movement). If not, go on to the next question.

What is the main purpose of your stay? Highly qualified employment: EU Blue Card. Employment (other): employed worker residence authorisation plus ADEM test. Intra-group assignment from abroad: intra-corporate transfer (ICT). Self-employed activity or business creation: self-employed worker permit. Investment: investor residence permit. Studies: student permit. Joining a resident relative: family reunification. Youth exchange (partner country): Working Holiday.

In all 'third-country' cases, remember: the D visa must be requested before entry.

Cerno Law Firm's takeaway

In Luxembourg, immigration is not a single pathway but a branching structure whose root is nationality. EU, EEA and Swiss citizens proceed by declarations; third-country nationals by prior authorisations; and several specific routes cater for particular profiles.

The key to a successful file comes down to three habits: identifying the right regime from the outset, respecting the order of the steps, and checking each threshold and each deadline on the official source rather than on an out-of-date summary. The immigration lawyers of Cerno Law Firm support individuals and employers in identifying the right pathway, preparing files and dealing with the administrations.
