Andorra is one of the most restrictive countries in Europe on this question. It has not permitted dual nationality, meaning acquiring another citizenship can cost you the Andorran one, and its naturalisation process requires residence measured in decades rather than years.
Quick facts
The consequence for a family in the United States is stark: an Andorran who takes American citizenship may lose their Andorran nationality, and a person born here to Andorran parents may face a choice rather than an entitlement to both. Establish the position before anyone acts.
What to establish
| Question | Why it matters | Where to ask |
|---|---|---|
| Effect of naturalising in the U.S. | Andorran nationality may be lost | Andorran authorities, first |
| Children born abroad | May face a choice at some point | Andorran authorities |
| Deadlines for choosing | Missing one can be decisive | Ask explicitly |
| Already naturalised elsewhere | Ask about your position | A lawyer, promptly |
| Property in Andorra | Rules differ by nationality | A lawyer there |
Ask explicitly about deadlines. Where a country requires a choice of nationality, that choice usually has to be exercised within a defined period, and missing it can settle the matter for you.
What to do
- Ask the Andorran authorities what naturalising elsewhere would mean for you.
- Do that before applying, not afterwards.
- Establish the children’s position and any deadline attached to it.
- Take legal advice specific to your circumstances.
- Gather the family’s Andorran documents.
- Take separate advice on property, where rules differ by nationality.
Required documents
- Andorran passport or identity document.
- Certificate of nationality.
- Birth certificate.
- Parent’s documents where the claim is by descent.
- U.S. naturalisation certificate where relevant.
- Legal advice specific to your case.
Where to enquire
With the authorities in Andorra, through the Permanent Mission in New York where it can assist.
Additional notes
Among the strictest in Europe
Andorra is not a country where dual nationality is quietly tolerated. Take the question seriously.
Ask about deadlines
Where a choice must be made, when it must be made matters as much as what you choose.
Property follows nationality
Rules on ownership differ between nationals and foreigners.
Take proper advice
A lawyer familiar with Andorran law is the right source. A website is not.
