Luxembourg Dual Citizenship
Clear answers about Luxembourg dual citizenship by ancestry: who qualifies, how long it takes, what it costs you in time and paperwork, and what life as a dual citizen looks like.
The Basics
For many of our clients, citizenship provides a sense of belonging and connection to their family roots and history. Once you obtain citizenship, you can get a Luxembourg passport, which ranks among the world's strongest, providing full freedom to live, work, study, or retire across all 27 European Union member states.
No. The United States permits dual citizenship under current law, and Luxembourg allows dual citizenship as well. You keep your US citizenship when you become a Luxembourg citizen.
No, Luxembourg does not tax foreign-sourced income of non-residents. You would owe taxes only if you maintain legal residence or generate specific income within the country.
Yes, once your citizenship is formally recognized, it establishes a legal lineage that can be passed down to future generations.
Eligibility
This depends on your specific family history and citizenship pathway. Some applicants qualify through a great-grandparent, others further back. The qualifying ancestor must have been born after 1815 within the modern-day borders of the Grand Duchy of Luxembourg.
LuxCitizenship's professional research team can assist in confirming your family's roots and determining whether you qualify for the citizenship recovery process. We perform specialized searches of Luxembourgish civil archives to locate the necessary vital records for your specific ancestor, providing the documented proof required for a successful application. Learn more about our genealogy research services.
Applicants typically need certified vital records to prove lineage. You do not need an apostille for any US or Canadian record. The exact list of requirements depends on your specific case, which we'll walk you through once you sign up.
This is not an uncommon situation, and it doesn't automatically rule out eligibility. We evaluate these cases individually, and we will point you to acceptable secondary documentation to submit to support the lineage information.
The Process
Timelines vary by case and depend largely on how quickly the client submits full documentation to our team after signing up. On average, once we submit the application to Luxembourg, ministry processing takes about 90 days. In total, the citizenship process typically takes 6 to 8 months under the Article 7 pathway and 10 to 12 months under Article 23 or Articles 7/23.
Yes, if you have family that previously applied, you only need to submit the vital records that are different from the ones they did. The document gathering part is one of the longest parts of the process, so the fewer records you need, the faster the process will move.
Not sure if anyone has applied through your ancestor? Search our verified ancestors database to see whether we have already worked with a client who shares the same Luxembourgish ancestor.
Yes, your family member may join your application as long as we have not yet submitted your application to Luxembourg for processing. In any case, they may also apply separately and would be able to reference your application so that they won't need to resubmit the same records as you.
Since 2016, LuxCitizenship has helped 3,500 Americans on the path to dual citizenship: more than 3,000 clients have obtained Luxembourg citizenship and another 500+ are currently applying.
Requirements
No, individuals pursuing citizenship by descent do not need to speak Luxembourgish or take the Sproochentest (language test) or civics course.
Spouses do not automatically get citizenship in Luxembourg and cannot apply for citizenship based on your ancestor (by virtue of marriage), but they may obtain citizenship through naturalization. The process will look different for them and includes language and civics requirements.
