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."
Puerto Rican citizenship
Based on the federal court ruling on "Colon v. U.S. Department of State", on June 4, 1998—and several months after the U.S. Government had accepted his renunciation—the U.S. State Department notified the president of the Puerto Rico Socialist Party, Juan Mari Brás, that they were rescinding their acceptance, and refused to accept Juan Mari Brás' renunciation, determining that Mari Brás could not renounce his American citizenship because he lived in Puerto Rico and not in another country foreign to the United States. This, said the federal agency, made Mari Brás a U.S. citizen.
