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 rejecting the renunciation, the Department noted that the Plaintiff in "Colón" demonstrated no intention of renouncing all ties to the United States, i.e., claiming to reject his United States citizenship, but nevertheless wishing to remain a resident of Puerto Rico. The Plaintiff's response was to claim a fundamental distinction between United States and Puerto Rican citizenship. The United States Department of State position asserted that renunciation of U.S. citizenship must entail renunciation of Puerto Rican citizenship as well. The court does decide to not enter to the merits of the citizenship issue; however the U.S. District Court for the District of Columbia rejected Colón's petition for a writ of mandamus directing the Secretary of State to approve a Certificate of Loss of Nationality in the case because the plaintiff wanted to retain one of the primary benefits of U.S. citizenship while claiming he was not a U.S. citizen. The Court described the plaintiff as a person, "claiming to renounce all rights and privileges of United States citizenship, [while] Plaintiff wants to continue to exercise one of the fundamental rights of citizenship, namely to travel freely throughout the world and when he wants to, return and reside in the United States." The court based this decision on the Immigration and Nationality Act section 8 U.S.C. § 1101(a)(38), which defines the term "United States", and evince that Puerto Rico is a part of the United States for such purposes.
