Dual Citizenship Recovery for Luxembourg citizens in the United States — 2026

Nationality rules differ enormously between countries, and this is not a page that can tell you whether you qualify. Some countries pass citizenship down indefinitely; others stop at one generation born abroad, require registration before a deadline, or do not permit dual nationality at all. What follows is how to find out for Luxembourg, and what to settle before you spend anything.

Quick facts

Luxembourg has six consular offices, in Estero, Kapolei, New York, San Francisco, Seattle and Washington, D.C. That is enough offices for the kind of office to matter as much as the distance to it.

Luxembourgish consular offices in the United States

Applications and enquiries go through the career post whose district covers your state, though the decision itself is taken in Luxembourg:

The questions that decide your case

• How far down does descent run? Through a parent is common; through a grandparent is much rarer; through a great-grandparent is unusual anywhere.
• Is there a deadline? Several countries require a child born abroad to be registered within a set period, after which the claim is lost.
• Does Luxembourg permit dual nationality? Yes. Luxembourg nationality is lost only by renunciation or by forfeiture. Acquiring another nationality is not a ground of loss at all, for anyone.
• Does the line pass through either parent? Some nationality laws were paternal for decades and were reformed later, sometimes with retroactive effect.
• What obligations come with it? Military service and tax residence attach to nationality in some countries regardless of where you live.

Documents a claim by descent normally rests on

• Birth certificates establishing the unbroken line, each certified for use abroad.
• Marriage certificates covering every change of surname in that line.
• The ancestor’s Luxembourgish passport, identity card or other proof of nationality.
• Evidence of whether and when an ancestor naturalised elsewhere, which in some countries breaks the line.
• Translations into French, German or Luxembourgish where required.

Before spending money on this

Ask the consular office what Luxembourgish law actually allows in your circumstances before engaging anyone to help with it. Genealogists and specialist firms exist and can be useful where records are old or scattered, but they are not a substitute for knowing whether the claim exists at all — and that answer is free.

If your own immigration position in the United States is unresolved, take advice from an immigration lawyer before approaching any foreign authority.

Luxembourg nationality and the U.S. oath

Article 55 of the Law of 8 March 2017 on Luxembourg nationality, in force since 1 April 2017, sets out the whole of it: nationality is lost by renunciation or by forfeiture. Voluntary acquisition of a foreign nationality is not among the grounds, and there is nothing to file before taking the U.S. oath.

Article 83 adds something worth knowing once you hold both: a person who holds Luxembourg nationality alongside one or more others is treated by Luxembourg public authorities as exclusively Luxembourgish. Forfeiture, under articles 62 to 64, reaches only nationality obtained by naturalisation, option or recovery, and only where it was obtained by false statements, fraud, concealment of important facts, forgery or a fraudulent marriage — and it can never leave someone stateless.
