Puerto Rican citizenship
On March 2, 1917, the Jones–Shafroth Act was signed, collectively making Puerto Ricans United States citizens without rescinding their Puerto Rican citizenship. In 1922, the U.S. Supreme court in the case of "Balzac v. Porto Rico" ruled that the full protection and rights of the U.S constitution do not apply to residents of Puerto Rico until they come to reside in the United States proper. Luis Muñoz Rivera, who participated in the creation of the Jones-Shafroth Act, gave a speech in the U.S. House floor that argued in favor of Puerto Rican citizenship. He declared that "if the earth were to swallow the island, Puerto Ricans would prefer American citizenship to any citizenship in the world. But as long as the island existed, the residents preferred Puerto Rican citizenship." The Jones Act allowed locals to renounce the United States citizenship and remain exclusively Puerto Rican citizens, at the cost of being stripped of the right to vote. Despite these arbitrary limitations, 287 residents completed the process to forfeit the statutory recognition.
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.
