Puerto Rican citizenship
In 1952, upon U.S. Congress approving the Constitution of the Commonwealth of Puerto Rico, also reaffirmed that Puerto Rican citizenship continued in full force. This was further reaffirmed in 2006 while the U.S. Senate probed into the President's Task Force on Puerto Rico's status. In 1953, U.S Ambassador Henry Cabot Lodge Jr., in a memorandum sent to the United Nations, recognized that "the people of Puerto Rico continue to be citizens of the United States as well as of Puerto Rico."
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.
