Andorran citizenship by naturalisation

Twenty years, with a recent-residence condition

The ordinary route requires twenty years of principal and permanent residence, which may be interrupted or continuous, plus principal and effective residence during at least the five years immediately before application. The applicant must prove actual qualifying residence; the authority can verify it. The separate ten-year school-based route is not the ordinary baseline.

Effective from 2026-06-04

Catalan B1 document for applicants under seventy

Applicants under seventy must provide the official Andorran B1 Catalan diploma or a recognised equivalent. The government identifies B1 as a CEFR level and assesses listening, reading, speaking, writing and language accuracy. The age exception concerns the diploma document; it should not be read as removing every integration requirement.

Effective from 2026-06-04

Integration is assessed separately

The administration assesses sufficient integration under the applicable regulations. The law identifies Catalan, Andorran history, geography and institutions as essential considerations and requires objective, non-discriminatory assessment. A language diploma alone does not establish that all naturalisation conditions are satisfied.

Criminal-record and public-interest conditions

An unexpunged conviction imposing at least one year of imprisonment for an intentional offence, or convictions for two or more intentional offences, bars this route. The government may also refuse naturalisation on public-order or national-interest grounds. Completing the residence period therefore does not guarantee citizenship.

Previous nationalities must be lost

A favourable initial decision is conditional on proving loss of all previous nationalities within five years of notification, together with a sworn declaration that the applicant has taken no action intended to undo that loss. An extension of up to two years is possible where the applicant proves that the renunciation process has begun. The government then grants nationality by decree, effective from the date the previous nationality or nationalities were lost; missing the deadline can cause the conditional decision to lapse.
