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."
Bills in U.S. Congress regarding the political status of Puerto Rico
In 2005, the U.S. House Committee on Resources concluded that Puerto Rico is still an unincorporated territory of the United States under the Territorial Clause, that the establishment of local self-government with the consent of the people can be unilaterally revoked by U.S. Congress, and Congress can withdraw, at any time, the American citizenship now enjoyed by the residents of Puerto Rico as long as it achieves a legitimate Federal purpose, in a manner reasonably related to that purpose.
