Work permit Luxembourg: the complete single-permit guide

Salaried employment · Non-EU nationals

If you are a non-EU national with a job offer in Luxembourg, the single permit (autorisation de séjour for salaried work) is the standard route to live and work legally. This guide explains who needs it, the labour-market test, the documents, the full procedure, realistic timelines and how it differs from the EU Blue Card, so you can move with a complete and compliant file.

Who needs a work permit?

EU, EEA and Swiss nationals do not need a permit to work in Luxembourg. Non-EU (third-country) nationals do. The single permit combines, in one document, the right to reside and the right to work for a salaried position with an employer established in Luxembourg. It is issued by the Immigration Directorate of the Ministry of Foreign and European Affairs, after the labour-market step involving the National Employment Agency (ADEM).

The labour-market test

Before hiring a non-EU worker, the employer must, in most cases, register the vacancy with ADEM and obtain a certificate confirming the right to recruit outside the EU preference pool. In practice this means the role is first opened to the local and EU labour market. This step is a frequent source of delay and refusal when handled informally, which is why we coordinate it with the employer from the start.

Eligibility conditions

• A genuine job offer or signed contract with an employer in Luxembourg.
• The employer has completed, or will complete, the ADEM vacancy declaration and obtained the recruitment certificate.
• You hold any qualification or authorisation required for the role, including recognition for regulated professions.
• You meet the general conditions of entry and stay, including a clean criminal record and adequate accommodation where required.

Documents typically required

• Valid passport and identity photographs.
• Signed work contract and employer declaration.
• Diplomas or professional qualifications, with apostille and certified translation where foreign.
• Extract from the criminal record and, depending on the situation, proof of accommodation.
• Curriculum vitae and any role-specific authorisations.

The procedure step by step

1. Employer step with ADEM. Vacancy declaration and recruitment certificate before the application is filed.
2. Temporary authorisation to stay. Applied for from abroad, before entry, with the complete file addressed to the Immigration Directorate.
3. Entry visa (type D). Where your nationality requires it, obtained on the basis of the authorisation.
4. Arrival and declaration. Arrival declaration at the commune within the legal deadline, plus the medical formalities where required.
5. Residence permit. Issuance of the single permit, valid for the work and stay.

Realistic timelines

The single permit depends on the ADEM step, the completeness of your file, qualification recognition where applicable and your nationality. A complete file with the employer steps done correctly moves predictably; an incomplete one triggers requests for additional documents that add weeks. We give you a realistic schedule up front and track the file to the decision so your employer can set a reliable start date.

Validity, renewal and changing jobs

The first single permit is typically tied to one employer and one occupation for a defined period, then renewable as conditions continue to be met. Rules apply when you change employer or sector, especially in the early period, so always check before signing a new contract. We advise on renewals and job changes to keep your status continuous.

Single permit or EU Blue Card?

If your role is highly qualified and your salary meets the threshold, the EU Blue Card is usually stronger: it adds intra-EU mobility and an accelerated family route. The single permit is the right route for standard salaried roles or where the Blue Card salary threshold is not met. We assess both and recommend the one that fits your profile. If you work for yourself, see the self-employed route.

Bringing your family

Once established, you may apply for family reunification for your spouse and children, subject to conditions on income and accommodation. Planning this from the outset avoids gaps between your arrival and your family joining you.

Common mistakes to avoid

• Starting work before the permit is issued.
• Skipping or mishandling the ADEM vacancy step.
• Foreign diplomas without apostille or certified translation.
• Assuming a regulated profession needs no qualification recognition.
