The US government does not officially endorse a policy for multiple nationalities of its nationals. On October 25, 2006, Mari Brás became the first person to receive a Certificate of Puerto Rican citizenship from the Puerto Rico Department of State. The Certificate of Puerto Rican Citizenship can be used to obtain dual nationality in Spain, as it is considered proof of Ibero-American heritage. Under Spanish statues, Organic Law 4/2000 and Royal Decree 557/2011, persons who have historic ties to Spain and can demonstrate their origin in an Ibero-American country are able to be naturalized without renouncing their previous nationality.
