I am British, living in Spain. I applied and have been granted an Irish Passport based on my parents nationality, both were born in Ireland. My Irish passport says 'Irish Citizen' therefore I have been told I now hold dual citizenship. My husband is British but our Spanish legal rep, has told us he can continue to reside in Spain based on my status as Irish Citizen. The application process was straightforward, I just needed my father's birth certificate and my parents' marriage certificate. I have also renewed my UK passport and declared my Irish passport on the form. Received my new UK passport last week. .
