Puerto Rican citizenship
On March 2, 1917, the Jones–Shafroth Act was signed, collectively making Puerto Ricans United States citizens without rescinding their Puerto Rican citizenship. In 1922, the U.S. Supreme court in the case of "Balzac v. Porto Rico" ruled that the full protection and rights of the U.S constitution do not apply to residents of Puerto Rico until they come to reside in the United States proper. Luis Muñoz Rivera, who participated in the creation of the Jones-Shafroth Act, gave a speech in the U.S. House floor that argued in favor of Puerto Rican citizenship. He declared that "if the earth were to swallow the island, Puerto Ricans would prefer American citizenship to any citizenship in the world. But as long as the island existed, the residents preferred Puerto Rican citizenship." The Jones Act allowed locals to renounce the United States citizenship and remain exclusively Puerto Rican citizens, at the cost of being stripped of the right to vote. Despite these arbitrary limitations, 287 residents completed the process to forfeit the statutory recognition.

In 1914, the entire Puerto Rican House of Delegates demanded independence from the U.S. Instead, the U.S. imposed the Jones Act of 1917, which mandated U.S. citizenship on the entire island. The passage of the Jones Act coincided with America's entry unto World War I, and it allowed the U.S. to conscript Puerto Ricans into the U.S. military. The Jones Act was passed over the unanimous objection of the entire Puerto Rican House of Delegates, which was the legislature of Puerto Rico at that time. 
In addition to subjecting Puerto Ricans to the military draft, and sending them into World War I, the Jones Act created a bicameral, popularly elected legislature in Puerto Rico (following ratification of the Seventeenth Amendment to the United States Constitution in 1913 providing for popular election of senators), a bill of rights, and executive functions similar to those in most states. Because Puerto Rico was not a state, it did not have electoral status for U.S. presidential elections. The Act authorized popular election of the Resident Commissioner, previously appointed by the President of the U.S.
