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.
Political status of Puerto Rico
More Puerto Ricans live stateside in the U.S. than in Puerto Rico. A 2009 report by the Pew Hispanic Center indicates that, as of 2007, 4.1 million Puerto Ricans lived in the mainland versus 3.9 million living in the Island. Since the 1967 referendum, there have been demands that stateside Puerto Ricans be allowed to vote in these plebiscites on the political status of Puerto Rico. Since the 1990s, the role of stateside Puerto Ricans in advocating for Puerto Rico in Washington, D.C., on issues such as the Navy's removal from Vieques and others has increased, especially given that there have been three voting members of the U.S. Congress who are stateside Puerto Ricans (two from New York City and one from Chicago), in contrast to Puerto Rico's single Resident Commissioner in the U.S. Congress with no vote.
