Is it possible to have two residencies? My wife now has a green card and residency in USA. I am a US citizen and also have residency in Spain. Our intention is to apply for Reagrupacion Familiar in Spain allowing my wife to share my residency in Spain and go to school in Spain for 8 months of the year. USCIS allows up to a year absence but also states that a green card holder must be present in USA for at least half the time of the first 3 years in order to attain permanent residency. The basic question again becomes, Is it legally possible to have ' dual residency ' in the two counties of USA and Spain?
