Article 7/23 - Combination Process

Your parent or grandparent may be Luxembourgish without knowing it.

If so, you may be eligible to apply for citizenship under the Article 7/23 process.

Watch our video to learn more about the process of applying for citizenship.  If you are ready to get started, take next steps below.

Eligibility Criteria

Who is Eligible to Apply Under Article 7/23?

If you are not eligible to apply through Articles 7 or 23, don't lose hope! The Article 7/23 Combination Process has allowed thousands of otherwise ineligible individuals to apply for Luxembourg citizenship through ancestry.

Who qualifies
  1. Anyone with a parent or grandparent (alive or deceased) who meets Article 7 eligibility criteria. When your parent or grandparent in the lineage is alive, while they are eligible to apply, too, it is not required in order for you to apply yourself.

Example: Your grandmother has an all-male lineage to your family's Luxembourg ancestor, but because your mother was born before January 1st, 1969, she did not automatically receive Luxembourg citizenship from your grandmother. This path, while it does require travel to Luxembourg, allows you to request recognition of your grandmother's citizenship (through Article 7) and then apply for citizenship yourself (through Article 23).

Important Information: If you have a minor child, you must apply for their citizenship at the same time as your own, or you cannot apply. They do not need to travel with you to Luxembourg. This is the law in Luxembourg, and the government never makes exceptions.

Frequently Asked Questions

Review Answers to Our Most Common Questions

Still have questions about your eligibility? We recommend completing our free Eligibility Test first to receive your preliminary results. You can then reach out to our team with any additional questions.

Who qualifies for Luxembourg citizenship under Article 7/23?
To qualify for the Article 7/23 process, you must have a parent or grandparent with an all-male lineage back to a Luxembourg-born ancestor. Your case is built in two steps: a mail-in application in which the Luxembourg government recognizes your parent’s or grandparent’s citizenship, followed by your own citizenship application.
Yes. As long as your parent or grandparent has a qualifying all-male lineage, you are eligible to apply. This holds whether the relative serving as your qualifying link is living or deceased.

This depends on the age of your children. Minor children are legally required to be included in your application. They do not need to travel to Luxembourg, but they must be registered.


Adult children cannot apply based on an ancestor three generations back. They become eligible once you become a Luxembourg citizen yourself, at which point they can apply through you.

Yes. The Article 7/23 process requires a short in-person trip to Luxembourg to submit your declaration. It is a single appointment rather than a residency requirement, and our team prepares every document in advance so the visit itself is brief.

No. The Article 7/23 process has no application deadline. 

No, Luxembourg and the U.S. allow dual citizenship, so you can maintain both your American and Luxembourg citizenships.

No. There is no language requirement to apply for Luxembourg citizenship under the Article 7/23 process.

Luxembourg citizenship is European Union citizenship. It gives you the right to live, work, study, and retire in any EU member state, access to one of the strongest passports in the world, and the ability to pass citizenship on to your children and generations to come.
