Moving to Luxembourg: The French (and Luxembourgish) You Need
By Language Lab editorial team
Moving to Luxembourg? Why French runs daily admin, where Luxembourgish and German fit in, the commune declaration, and how to prepare.
What language do you need to move to Luxembourg?
Luxembourg is one of the most multilingual countries in the world, juggling three official languages — Luxembourgish, French and German — plus heavy use of English in its international finance sector. For a newcomer, the single most useful language to learn first is French: it dominates administration, daily service, shops, restaurants and much of working life. German appears in media and some official contexts, and Luxembourgish (Lëtzebuergesch) is the national language of identity, spoken at home and increasingly required for long-term integration and citizenship.
The practical path is to build functional French for the commune, banks and daily life, then add Luxembourgish over time as a signal of genuine commitment — it is the language that opens the door to citizenship and deeper belonging. English will carry you in finance and among the huge cross-border and expat community, but French is what makes everyday Luxembourg feel accessible.
The commune declaration and residence
When you arrive you make a declaration of arrival at your local commune (town hall) within a few days, and if you stay beyond three months you complete a residence registration. EU citizens register at the commune; non-EU movers need a temporary authorisation to stay arranged before arrival, then a residence permit. The commune process is typically in French (or German), so the vocabulary of registration is what you want ready.
| French / Luxembourgish | English |
|---|---|
| Bonjour, je viens faire ma déclaration d'arrivée. | Hello, I've come to make my arrival declaration. |
| Moien (Luxembourgish) | Hello |
| Je voudrais m'inscrire à la commune. | I'd like to register at the commune. |
| Où se trouve la mairie? | Where is the town hall? |
| Je cherche un logement à louer. | I'm looking for accommodation to rent. |
| Merci / Merci villmols (Lux.) | Thank you / thank you very much |
The visa side
EU citizens register at the commune; non-EU movers need a temporary authorisation to stay before arrival, then a residence permit. Confirm current requirements with the Luxembourg authorities before you travel.
How to prepare
Focus on functional French for the commune, banks and daily life, and pick up a few Luxembourgish greetings (Moien, Merci villmols) as a sign of respect. Rehearse the real situations out loud — the arrival declaration, the bank, an apartment viewing. Language Lab teaches practical French for relocation through voiced scenarios and Sonia, a live AI tutor you speak with out loud, across 50 languages, free to start. Our full guide to moving to Luxembourg has the first-week steps.
Frequently asked
Do I need Luxembourgish to live in Luxembourg?
Not to function day to day — French dominates administration and daily life, and English is widely used in finance and among the expat community. But Luxembourgish (Lëtzebuergesch) is the national language of identity and is increasingly needed for long-term integration and citizenship, so it's worth learning over time.
Which language should I learn first for Luxembourg?
French. It's the most useful for the commune, banks, shops, restaurants and much of working life. German appears in media and some official contexts, and Luxembourgish is best added later as a commitment to long-term integration.
