Spain Introduces Citizenship Option for Foreigners in 2026

Spain's Ministry of Foreign Affairs has announced the conditions under which foreigners can acquire Spanish nationality through the option pathway, identifying four distinct qualifying categories. The first group includes individuals who are or have been under the parental authority of a Spanish citizen, requiring them to file their declaration within two years of turning 18 or becoming legally emancipated.

The second group consists of anyone whose father or mother was Spanish and born in Spain, with no time limit for application. The third group pertains to individuals who, after age 18, have their parentage officially established or discover their place of birth in Spain, having a two-year window from the date of confirmation.

The fourth group includes those adopted by Spanish citizens after reaching 18, also with a two-year deadline from the formalization of adoption. The option pathway is distinct from naturalization through residency and is designed for individuals with existing ties to Spain.
