Luxembourg Option by Family

Summary

Luxembourg's option procedure can help some adults acquire Luxembourgish nationality when a parent, adoptive parent, or grandparent is or was Luxembourgish, but that nationality did not pass down at the relevant generation.

This is a specific family option route, not a broad ancestry route. It does not reach an older Luxembourgish ancestor by itself. It is also different from the older Luxembourg ancestor-reclamation route tied to an ancestor who was Luxembourgish on 1 January 1900; that older reclamation route had statutory deadlines and should not be treated as a fresh pathway for new users.

Eligibility

• You are an adult
• You do not already hold Luxembourgish nationality
• A parent or adoptive parent is or was Luxembourgish, and Luxembourgish nationality was not passed down to you; or a grandparent is or was Luxembourgish, and Luxembourgish nationality was not passed down to your parent
• You can document the family line with civil-status records
• You can provide a certificate of Luxembourgish nationality for the parent, adoptive parent, or grandparent
• You meet Luxembourg's good-repute requirement

If a Luxembourgish parent was already Luxembourgish when you were born, you may already be Luxembourgish by filiation. In that situation, the better next step is usually to prove existing nationality rather than use this option procedure.

What This Route Allows

If approved, this route can lead to citizenship in Luxembourg. Citizenship is the national status itself, not a residence permit: you can document the citizenship, apply for citizen identity or passport documents, and live in Luxembourg without a separate immigration permit.

What This Route Is Not

This is not automatic citizenship. Naturalization, registration, and restoration routes usually require an application, supporting documents, and a decision by the relevant authority.

Key Documents

• Passport and identity documents
• Birth and parentage records for each generation
• A full copy of the birth certificate of the Luxembourgish parent, adoptive parent, or grandparent
• A certificate of Luxembourgish nationality for that parent, adoptive parent, or grandparent
• Criminal-record certificates or similar documents from countries where you are or were a national, and countries where you have lived as an adult during the lookback period Luxembourg requires
• Translations into French, German, English, or Luxembourgish where needed

Next Steps

1. Identify the Luxembourgish parent, adoptive parent, or grandparent.
2. Confirm where the nationality chain stopped: from the parent to you, or from the grandparent to your parent.
3. Gather civil-status records for each link.
4. Request or verify the certificate of Luxembourgish nationality for the Luxembourgish family member.
5. Review the current option-procedure checklist.
6. File the option declaration in person with the competent civil registrar. If you live outside Luxembourg, the declaration is made through the civil registrar of the City of Luxembourg.
