Foreign nationals can apply for citizenship in Luxembourg after five years of residence. Luxembourg permits dual nationality but if you are thinking of applying and you hold other passports in addition to a British one, check with your consulate to ensure you won’t lose another citizenship if applying for Luxembourgish nationality.
With an increasing number of foreign residents, Luxembourg made significant changes to its citizenship laws and these came into effect in April 2017. There are a number of routes open to UK nationals who wish to apply for citizenship. These include the simplified 20 year option for anyone who has lived in Luxembourg for 20 years or more, or the slightly more complicated 5 year rule. Full details are available via the links below but the key requirement is a basic understanding of Luxembourgish and Luxembourgish life.
You can teach yourself via the online courses run by the INS or engage a private teacher. If you wish to apply under the 20 year rule, you must have followed an accredited language courses for 24 hours. All the accredited courses in Luxembourg can be found below. Please note that there is increasing demand for Luxembourgish classes so apply as soon as you can and be prepared for a wait.
