Maritime Neighbors (Closest Foreign Territories)

Political Status Implications

• No land borders — it's an archipelago (main island + Vieques, Culebra, minor islets)
• U.S. customs & immigration apply — domestic travel from mainland U.S.
• No passport needed for U.S. citizens arriving from states
• Foreign nationals need U.S. visa/ESTA
• EEZ: 200-nautical-mile Exclusive Economic Zone — managed by U.S.

Strategic Location

Puerto Rico sits on the Anegada Passage — key shipping lane between Atlantic and Caribbean. Hosts major U.S. military installations (historically Roosevelt Roads, now Muniz ANGB).

While it has no "neighboring countries," its maritime neighborhood shapes its economy, ecology, and geopolitics.
