Which U.S. Territory Lies East of Cuba? Not Hispaniola.

The question contains a geographic error. Hispaniola (Haiti + Dominican Republic) lies east of Cuba but is not a U.S. territory—it comprises two sovereign nations.

U.S. Territories East of Cuba

• Puerto Rico — ~500 km east of Cuba's eastern tip; U.S. territory since 1898.
• U.S. Virgin Islands (St. Thomas, St. John, St. Croix) — further east, ~1,100 km from Cuba; U.S. territory since 1917.
• Navassa Island — uninhabited, between Haiti and Jamaica; claimed by U.S. (1857), disputed by Haiti.

Clarification

If the question implies "part of the U.S. and east of Cuba," the answer is Puerto Rico (closest) or the U.S. Virgin Islands. Hispaniola is independent.
