Puerto Rican citizenship
A 1918 official report from the American colonial governor of Puerto Rico to the U.S. Secretary of War, this one after the Jones Act of 1917, had become law, states that the "passports...[are used to] prove a person's nationality," thus making clear that Puerto Rican citizenship and Puerto Rican nationality were one and the same. The United States government also recognizes this status in its own records. For example, the CIA World Fact Book, states that the nationality of Puerto Ricans is not "American" but, in fact, ""Puerto Rican"." The Spanish Government also recognizes Puerto Ricans as a people with Puerto Rican, "and not American," citizenship. It also provides Puerto Rican citizens privileges not provided to citizens of several other nations, such as Haití, Jamaica, Trinidad y Tobago y Guyana. Since 2007, the Government of Puerto Rico has been issuing "Certificates of Puerto Rican Citizenship" to anyone born in Puerto Rico or born outside of Puerto Rico with at least one parent who was born in Puerto Rico.
Statelessness
Mari Brás claimed that as a Puerto Rican national born and raised in Puerto Rico, he was clearly a Puerto Rican citizen and therefore had every right to continue to reside, work, and, most importantly, vote in Puerto Rico. The State Department responded promptly, claiming that Puerto Rican citizenship did not exist independent of American citizenship, and in 1998, the department rescinded its recognition of his renunciation of citizenship. The official response to Mari Brás stated that Puerto Rican citizenship existed only as an equivalent to residency. However, the Puerto Rico State Department issues certificates of citizenship to people born outside of Puerto Rico to a Puerto Rican parent, including some people who may have never resided in the territory.
