I was born in Spain in 1982 to American parents who were in the U.S. military and stationed in Rota. We moved to the U.S. when i was 2.5 years old, and I have not lived in Spain since. I have a Spanish birth certificate and would really like to reclaim Spanish citizenship (I currently live in London and visit Spain quite frequently). My question is am I able to reclaim citizenship (I'm assuming I did once have it) and, if so, how would I go about doing so?

Many thanks for any help you can offer!!
