Puerto Rican citizenship
Puerto Rican citizenship was first legislated by the United States Congress in Article 7 of the Foraker Act of 1900 and later recognized in the Constitution of Puerto Rico. Puerto Rican citizenship existed before the U.S. takeover of the islands of Puerto Rico and continued afterwards. Its affirmative standing was also recognized before and after the creation of the Commonwealth of Puerto Rico in 1952. Puerto Rican citizenship was recognized by the United States Congress in the early twentieth century and continues unchanged after the creation of the Commonwealth of Puerto Rico. The United States government also continues to recognize a Puerto Rican nationality. Puerto Rican citizenship was once also recognized by the Spanish Government, which recognized Puerto Ricans as a people with Puerto Rican, and not American citizenship. It also at one time granted Spanish citizenship to Puerto Ricans on the basis of their Puerto Rican (and not American) citizenship.
Dependent territory
Under the Constitution of Puerto Rico, Puerto Rico is described as a Commonwealth and Puerto Ricans have a degree of administrative autonomy similar to citizens of a U.S. state. Puerto Ricans "were collectively made U.S. citizens" in 1917 as a result of the Jones-Shafroth Act. The commonly used name in Spanish of the Commonwealth of Puerto Rico, "Estado Libre Asociado de Puerto Rico", literally "Associated Free State of Puerto Rico", which sounds similar to "free association" particularly when loosely used in Spanish, is sometimes erroneously interpreted to mean that Puerto Rico's relationship with United States is based on a Compact of Free Association and at other times erroneously held to mean that Puerto Rico's relationship with United States is based on an Interstate compact. This is a constant source of ambiguity and confusion when trying to define, understand and explain Puerto Rico's political relationship with the United States. For various reasons Puerto Rico's political status differs from that of the Pacific Islands that entered into Compacts of Free Association with the United States. As sovereign states, these islands have full right to conduct their own foreign relations, while the Commonwealth of Puerto Rico has territorial status subject to United States congressional authority under the Constitution's Territory Clause, "to dispose of and make all needful Rules and Regulations respecting the Territory… belonging to the United States.". Puerto Rico does not have the right to unilaterally declare independence, and at the last referendum (1998) the narrow majority voted for "none of the above", which was a formally undefined alternative used by commonwealth supporters to express their desire for an "enhanced commonwealth" option.
