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."
Juan Mari Brás
On July 11, 1994, Mari Brás renounced his American citizenship at the American Embassy in Caracas, Venezuela. "He did this to test a technicality in United States citizenship laws.", according to writer Mary Hilaire Tavenner Brás believed that a person holding United States citizenship and who subsequently renounces his citizenship would be deported to his country of origin. As Puerto Rico is a territory of the United States, Brás theorized the U.S. Department of State would have to deport him or any Puerto Rican who renounced his or her U.S. citizenship to Puerto Rico. The U.S. State Department approved Mari Brás' renunciation of his American citizenship on November 22, 1995.
