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.
Demographics of New York City
New York City has the largest Puerto Rican population outside of Puerto Rico. Attributable to the changing citizenship status of the island's residents, Puerto Ricans can technically be said to have come to the City first as immigrants and subsequently as migrants. The first group of Puerto Ricans moved to New York in the mid-19th century, when Puerto Rico was a Spanish colony and its people Spanish subjects. The following wave of Puerto Ricans to move to New York did so after the Spanish–American War of 1898 made Puerto Rico a U.S. possession and after the Jones–Shafroth Act of 1917 gave Puerto Ricans U.S. citizenship, which allows travel without the need of a passport between the island and the United States mainland. The largest wave of migration came in the 1950s, in what became known as "The Great Migration"; as a result, more than a million Puerto Ricans once called New York City home. Presently the Puerto Rican population is around 800,000.
