Dual citizenship

Dual Citizenship: 

Even though Luxembourg accepts dual citizenship for nationals, or third country nationals residing in Luxembourg, and offers options to reclaim the Luxembourg nationality in case it was lost, or based on ancestry, Luxembourg has not signed any bilateral agreement with any other country on that specific matter. Please note that applicants not being Luxembourg nationals should always verify with the competent authorities of their country of citizenship whether the law of this first country also accepts the principle of dual (or multiple) citizenship, while Luxembourg nationals willing to acquire a third country citizenship are invited to check with the foreign country authorities.

To finalize the reclamation procedure you will have to go to Luxembourg in person to submit all the required documents to the State Registrar.

The law of October 23, 2008 mainly allows the following situations:

  1. Luxembourg nationals to have a dual citizenship by acquiring the nationality of a third country
  2. Luxembourg nationals having lost their citizenship while acquiring the nationality of a third country before the law of 10/23/2008 may reclaim it based on Articles 14 or 31 of the law
  3. Foreigners of Luxembourg descent with a direct ancestor who was with the Luxembourg nationality on January 1, 1900 may reclaim the nationality based on Article 29 of the law. It is to be mentioned that this particular option will expire on December 31, 2018

 To apply, please refer to the website links

and  where you can find all the necessary forms.

See the brochure in English with the last update to the law of October 23, 2008.

Please refer to the brochure to be sure you gather all the documents applying to your own situation.
