Puerto Rican citizenship
On April 12, 1900, the United States Congress enacted the Foraker Act of 1900, which replaced the governing military regime in Puerto Rico with a civil form of government. Section VII of this act created a Puerto Rican citizenship for the residents "born in Puerto Rico and, therefore, subject to its jurisdiction." The Puerto Rican citizenship replaced the Spanish citizenship that Puerto Ricans held at the time in 1898. Such Puerto Rican citizenship was granted by Spain in 1897. This citizenship was reaffirmed by the United States Supreme Court in 1904 by its ruling in which denied that Puerto Ricans were United States citizens and labeled them as noncitizen nationals. In a 1914 letter of refusal to the offer of U.S. citizenship and addressed to both the President of the United States and the U.S. Congress, the Puerto Rico House of Delegates stated ""We, Porto Ricans, Spanish-Americans, of Latin soul ... are satisfied with our own beloved Porto Rican citizenship, and proud to have been born and brethren in our own motherland."" The official 1916 Report by the American colonial governor of Puerto Rico to the U.S. Secretary of War (the former name for the Department of Defense), addresses both citizenships, the Puerto Rican citizenship and United States citizenship, in the context of the issuance of passports, further evidencing that the Puerto Rican citizenship did not disappear when the Americans took over the island in 1898.
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.
