Puerto Rico, as a U.S. territory, is governed by the United States Federal Government. The Commonwealth of Puerto Rico is considered domestic travel from the United States, as long as you don’t touch down in a foreign place or port before arriving in Puerto Rico.
U.S. citizens and lawful permanent residents don’t need a passport to visit
Puerto Ricans, as U.S. citizens, don’t need a passport to go to the rest of the United States
When traveling to Puerto Rico, you only need a government-issued ID or Permanent Resident card
In other words, mainland U.S. travelers and Puerto Ricans are all United States citizens. You only need a valid ID, such as a driver’s license, to confirm citizenship for travel to and from Puerto Rico and to the 50 U.S. states or American territory.
