There are special provisions governing children born in some current and former U.S. territories or possessions, including Puerto Rico, the Panama Canal Zone, the Virgin Islands, Guam, and the Northern Mariana Islands. For example, states that "All persons born in Puerto Rico April 11, 1899, and ... January 13, 1941 ... residing on January 13, 1941, in Puerto Rico ... [and persons born in Puerto Rico on or after January 13, 1941, ... are citizens of the United States at birth."
