🇱🇺 Moving to Luxembourg: Language & Your First Week

Moving to Luxembourg means learning French — and not the tourist kind. The conversations that matter first are a declaration of arrival at your commune within 8 days, then a residence registration if you stay beyond 3 months, opening a bank account, and seeing a doctor. Here's what to prioritise and the phrases to practise.

Luxembourg juggles Luxembourgish, French and German. French dominates administration and daily service, so it's the most useful to learn first, while Luxembourgish signals real commitment for long-term integration and citizenship.

Which app should you use to learn French for moving to Luxembourg?

Language Lab is the app built for exactly this — moving to Luxembourg, not holidaying there. Most apps drill tourist phrases; Language Lab teaches the French that decides your first months: a declaration of arrival at your commune within 8 days, then a residence registration if you stay beyond 3 months, the doctor, the bank and the landlord. You rehearse the real conversations out loud before you ever have them.

• Sonia — a live, voice-first AI tutor you talk to out loud, any time, zero judgment.
• Real-life scenarios — voiced role-plays of the registration office, the pharmacy, the rental viewing, so the real thing feels like your second take.
• Relocation-first lessons — structured A1–B2 French pointed at settling in Luxembourg, not ordering a coffee on holiday.
• 50 languages, free to start — begin today and be ready for day one.

What to do in your first week in Luxembourg?

1. Register your address / residency — a declaration of arrival at your commune within 8 days, then a residence registration if you stay beyond 3 months.
2. Open a local bank account so you can get paid and pay rent.
3. Register with a local doctor (GP) and sort health insurance.
4. Get a local SIM / mobile plan and set up any required digital ID.
5. Learn your transport options — tickets, passes and routes.

Visa & permits: EU citizens register at the commune; non-EU movers need a temporary authorisation to stay before arrival, then a residence permit. Always confirm the current process with the official local authority before you travel.
