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.

Manuel Olivieri Sanchez, a court interpreter at the time, became enraged in what he viewed as a violation of the civil rights of his fellow countrymen. He encouraged his fellow Puerto Ricans to protest by telling them that "If you are not allowed to vote, don't answer the draft call". Olivieri Sanchez led a legal battle for the recognition of the Hawaiian Puerto Ricans as citizens of the United States. In the first legal battle the lower court ruled in favor of the county clerk, however Olivieri Sanchez did not give up the fight and took the case before the Territorial Supreme Court, which reversed the decision of the lower court, granting the Puerto Ricans of Hawaii their United States citizenship.
