How good does my Spanish language level have to be to get citizenship?

If you’re a non-native Spanish speaker who wants to obtain Spanish nationality after ten years of residency, you will have to sit a Spanish language exam if you want to obtain citizenship. Every year, thousands of foreigners who want to become Spanish nationals have to prove their integration into Spanish society by putting their Spanish language skills and general knowledge about Spain to the test with two exams. Therefore, you don’t have to be fluent in Spanish in order to be eligible for Spanish nationality through residency, but you do have to have a decent grasp of Spanish.
