# Ordinary adult naturalisation Ordinary adult naturalisation combines five years of lawful residence, a continuous final year, Luxembourgish language evidence, civic knowledge and good repute. Scope: Ordinary adult naturalisation, not acquisition by option, descent or recovery; residence, language, civic and character conditions must all be examined. Jurisdiction: Luxembourg — nationality law and Ministry of Justice decisions. Sources reviewed 2026-09-17; review due 2026-12-16. General information, not legal advice or a finding of eligibility. Requirements depend on the route, applicant and filing date. Verify the official instructions before applying. ## Five years with an uninterrupted final year An adult applicant must have resided legally in Luxembourg for at least five years. The final year immediately before the naturalisation application must be uninterrupted; the rule is not simply five years elapsed since first obtaining a residence document. Evidence: conditional.

The history/European-integration course module is automatically waived for holders of a CAI civic-education attendance certificate or a citizens' pact certificate for the minimum six-hour Luxembourg overview; this waiver does not apply to the test taken without course attendance. A physical or mental condition preventing language or civic learning may support a ministerial exemption request with a specialist doctor's certificate. Evidence: conditional.

Applications are made in person to the local civil registrar and examined by the Ministry of Justice; nationality takes effect through a favourable ministerial order. Evidence: conditional.

Retention also depends on the original country's nationality law. Evidence: conditional.

Document acceptance, residence continuity and character restrictions require individual assessment, and no approval or processing-time guarantee is given. ## Explore this passport - [Passport rank and travel access](https://multipassrank.com/passport/luxembourg) - [Tax residence & income](https://multipassrank.com/passport/luxembourg/taxes) - [Country-profile JSON, including sources and scoped requirements](https://multipassrank.com/api/v1/country-profiles/LU) - [Multiple-citizenship policy guide](https://multipassrank.com/dual-citizenship-countries) [Canonical page](https://multipassrank.com/passport/luxembourg/citizenship)
