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."
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.
