SPANISH CITIZENSHIP THROUGH OTHER OPTIONS
1. Original Spaniards
The most common way to obtain Spanish citizenship is to be of Spanish origin:
Those born to a Spanish father or mother.
Those born in Spain when they are the children of foreign parents if, at least one of the parents, was born in Spain (except the children of diplomats).
2. Citizenship by use
You can also get Spanish citizenship by use. This is the case when a person has used the Spanish nationality for ten years, on a continuous basis, in good faith (without being aware of the actual situation, that is, they are not actually Spanish). Anyone in that situation is entitled to Spanish nationality, based on a title registered in the Civil Registry.
3. Citizenship by option
To opt for Spanish citizenship means that someone can choose it and it is a benefit offered to foreigners who comply with certain conditions:
Those persons who are or have been subject to the parental authority of a Spaniard.
Those persons whose father or mother was/is Spanish and was born in Spain.
Those whose determination of filiation or birth in Spain occurs after the age of eighteen. In this case, they have to apply within two years from the time the filiation or place of birth is determined. If they do not do so within two years, they can go on to reside in Spain for one year and apply for citizenship then.
Those whose adoption by Spaniards occurs after their eighteenth birthday. In this case, the right to opt for the Spanish nationality exists until two years have passed since the adoption was established. If they do not do so within two years, they can go on to reside in Spain for one year and apply for citizenship then.
There is a lot of movement in this regard and a new law on the rules for descendants of Spaniards is already in the Senate. We will keep you updated!
