How Spain citizenship works for DNV holders
Standard naturalisation requires ten years of legal residence: five on the DNV plus five on long-term residence is the most common path for nomad-visa holders. The Spanish residency clock counts almost any legal status, so DNV holders are never penalised for the route they took in.
The shortcut: Ibero-American nationals qualify after just two years of legal residence. This includes most of Latin America (Argentina, Mexico, Colombia, Chile, Peru, and 13 others), plus the Philippines, Equatorial Guinea, Andorra, and Portugal. It is the fastest path to EU citizenship for those passports, by a wide margin. Sephardic Jews historically had a separate accelerated route, but that programme closed to new applicants in 2019.
Two exams are mandatory: the DELE A2 Spanish language certificate, and the CCSE (Conocimientos Constitucionales y Socioculturales de España) cultural and constitutional exam. Both are run by the Instituto Cervantes.
Spain generally does not permit dual citizenship with non-Ibero-American countries, so American, British, Canadian, and most other applicants are formally required to renounce. Enforcement is largely nominal: Spain doesn't notify origin countries of the renunciation, and most applicants retain their original passport in practice. This is widely understood but legally unsettled, and worth discussing with an immigration lawyer before proceeding.
