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 Ricans
The federal Naturalization Act, signed into law on March 26, 1790 by George Washington, explicitly barred anyone not of the White "race" from applying for U.S. citizenship. This law remained in effect until the 1950s, although its enforcement was tightened in the late nineteenth century regarding Asian immigrants, and by the Johnson-Reed act of 1924 imposing immigration quotas. In short, until late in the twentieth century, only immigrants of the White "race" could hope to become naturalized citizens. The people of Puerto Rico were declared U.S. citizens in 1917.
