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."
Union of Puerto Rico
The most divisive aspect of the Jones act was United States citizenship for Puerto Ricans. Both Muñoz, and the UPR delegates in Washington opposed Puerto Rican-U.S. Citizenship. Muñoz, in February 1914, introduced his own bill for the continuation of Puerto Rican citizenship- supported by the UPR delegates. However, dejected, the UPR delegates eventually chose to accept the provision "of individual citizenship outlined in the Shafroth bill".
