Does Spain allow dual citizenship? (2026)
Restricted — dual citizenship only with Ibero-American countries and a few others; otherwise you renounce.
Spain restricts dual citizenship. It's allowed with Ibero-American countries, Andorra, the Philippines, Equatorial Guinea and Portugal; for other nationalities, naturalising as Spanish generally requires renouncing your previous citizenship — though descent and Memory-Law routes are treated differently.
Does Spain allow dual citizenship?
Spain permits dual nationality by treaty and history with a defined list of countries (most of Latin America, plus Andorra, Portugal, the Philippines and Equatorial Guinea). Applicants from other countries are normally asked to formally renounce their prior nationality when naturalising.
The catch to watch
The renunciation is a declaration Spain records; your original country may not actually recognise it, but Spain requires the statement. Citizenship by descent and the Democratic Memory Law generally don't require renunciation.
How dual citizenship arises
By descent from a Spanish parent, via the Memory Law (grandchildren of exiles), or by naturalisation after residence — with renunciation unless you're from a listed country.
