How to register with your commune when you move to Luxembourg (déclaration d'arrivée)
When you move to Luxembourg you must declare your arrival at your commune's population office (bureau de la population). EU citizens have 8 days; third-country nationals have 3 working days. You bring a valid ID or passport, proof of address, and family certificates if relevant. Registration assigns your national identification number (matricule) and opens the door to social security, a tax card, banking and more.
