5 Easiest Countries for Second Passport for US Citizens

4. Spain

As another European country that recognizes dual citizenship with the US, Spain stands out as one of the easiest countries for US residents to obtain a second passport through its residency-by-investment program. The Golden Visa permits an individual to make a substantial investment of €500,000 and maintain this investment for five years. Continuous residence for five years in the country would lead to permanent residency status, which can then be converted into citizenship in another five years.
