There is no card to collect and no queue at an immigration office. For an EU citizen, residence in Luxembourg is a declaration filed at your commune and a slip of paper you receive on the spot. The simplicity is real, but the paperwork behind it is where people slip.
What is the rule for residence in Luxembourg for EU citizens?
Citizens of the EU, the EEA (Iceland, Liechtenstein, Norway) and Switzerland are treated alike. You may live in Luxembourg for more than 90 days if you work, study, or have sufficient resources and health insurance. According to Guichet.lu, you declare your arrival to the commune, then file a registration declaration (déclaration d'enregistrement) within three months of arriving. You are given the attestation d'enregistrement immediately. Guichet.lu does not state a fee; the amount can differ from one commune to another, so ask.
Which documents do you need?
You always need a valid ID card or passport. After that, it depends on your situation.
- Employee: a work contract dated and signed by both parties, or a signed job offer. A marginal activity of under 10 hours a week does not count.
- Self-employed: an establishment authorisation or professional authorisation where required, or a service contract.
- Inactive person (retiree, person of independent means): proof of sufficient resources and proof of health insurance covering all risks in Luxembourg.
- Student: proof of enrolment at an approved institution, proof of resources (an oral declaration is accepted) and health insurance.
- Family member: the registration certificate of the EU citizen you join, and proof of the family link or lasting relationship.
What happens to the registration certificate afterwards?
It records where you live and it has no expiry date. You will use it with your bank, your landlord and various offices. It does not replace your passport and, as Guichet.lu describes it, it carries no photo or nationality.
The commune registration also feeds your personal identification number. If you are waiting for it, see your Luxembourg matricule number.
Not sure which category you fall into: a remote worker employed abroad, a pensioner with a small income, a partner who does not work yet? Moovy can check the official criteria with you and tell you which documents to prepare. Only the commune and the immigration authorities decide, but the preparation is half the work.
What can make a right of residence fragile?
Guichet.lu lists some risks.
- Becoming an unreasonable burden on social assistance. The right of residence can be withdrawn; you then have a month to present your observations.
- No health insurance as an inactive resident. Cover for all risks is a condition, not a nicety; see healthcare in Luxembourg for expats.
- A short job instead of a real one. Under 10 hours a week does not give you worker status.
Involuntary unemployment does not make you lose your status as a worker, according to the same pages.
What about permanent residence?
After five years of legal and uninterrupted stay, you and eligible EU family members living with you may ask for a permanent residence certificate from the Direction générale de l'immigration. It is not automatic and you request it; keep proof of every year of residence, such as payslips, leases and certificates.
What changes for non-EU citizens, Swiss and British people?
Swiss citizens follow the same steps as EU citizens. British nationals are third-country nationals since Brexit. Those who were resident in Luxembourg on 31 December 2020 hold a residence document under the Withdrawal Agreement; others follow the third-country rules. For an employee that means a long-stay visa (visa D) requested abroad before entry, because an application made once you are in Luxembourg is inadmissible. Our article moving to Luxembourg from the UK explains the sequence.
What should you do right after registering?
Registration is the first domino. Once you have the certificate, your employer's social security declaration, your tax card and your bank account follow. The full order is in the guide to moving to Luxembourg. Keep a scan of the certificate on your phone: you will be asked for it more often than you expect.
How should different profiles prepare their file?
The same three-month window hides different realities.
An employee starting in Luxembourg should bring the signed contract, not a draft. Guichet.lu asks for a contract dated and signed by both parties, or a signed job offer. If the contract is still being negotiated when you arrive, residence still works, but ask your employer for the signed version before the appointment.
A remote worker whose employer is abroad is a more delicate case. The pages describe categories, not "digital nomads": you register as an employee, a self-employed person or an inactive person, depending on what you really are. The official pages do not say which category suits a person employed and paid abroad, so ask the commune before you travel, because the answer changes your documents (an employment contract, proof of resources, or an authorisation).
A retiree relies on resources and health insurance. If your pension is paid by another EU country, you will normally need an S1 form to be covered by the Luxembourg health fund; see healthcare in Luxembourg for expats.
A student needs enrolment at an approved institution, a statement of resources (an oral declaration is accepted) and health insurance.
A family member must bring the registration certificate of the person they are joining and proof of the relationship.
What is the timeline from day one?
- Day one: declare your arrival at the commune. Take your ID and, if you can, the supporting document for your category.
- Within three months: file the registration declaration. Most people do both on the same visit.
- Immediately afterwards: receive the registration certificate.
- Weeks later: the matricule, the social security card and the tax card follow, depending on your situation.
- After five years: you can ask for permanent residence.
If you are mid-way, with a deadline looming, it is better to go to the commune with an incomplete file and ask what is missing than to wait for a perfect one.
What about the right to work and to access benefits?
An EU citizen does not need a work permit. Registering as a resident is a right linked to your activity, and it also supports other steps: the national employment agency (ADEM) asks for registration, the school asks for a certificate of residence, and landlords and banks ask for the same slip. For unemployment rules and the labour market, read working in Luxembourg.
What do you need to keep for your residence in Luxembourg file?
Keep everything. The five-year clock for permanent residence runs on legal and uninterrupted stay, and proof is your job later. A simple folder, paper or digital, with the registration certificate, successive leases, payslips or proof of resources, and health insurance certificates will save you weeks if the immigration directorate asks questions. If you change category, for example from student to employee, tell the commune and keep both sets of documents.
Official pages change. The Guichet.lu page quoted here was updated on 1 October 2026, so check it again just before you go to the commune.
