>>Do not abbreviate the names of U.S. territories. There are 16 such territories; 11 of them are small islands, reefs or atolls in the Caribbean or the Pacific, without native populations. The others — Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa — are self-governing, unincorporated territories. They send nonvoting representatives to the U.S. Congress.
Residents of Puerto Rico, the U.S. Virgin Islands, Guam and the Northern Marianas are U.S. citizens; American Samoans are considered noncitizen U.S. nationals. Residents of the territories cannot vote in presidential elections, though their delegates participate in national political conventions to choose the nominees.
For datelines, use the community followed by the unabbreviated name of the territory: SAN JUAN, Puerto Rico.<<
