Do you need a passport to go to Guam?

Even though Guam is located over 2,000 miles away from the closest U.S. airport of Honolulu which is not even the Lower 48 states, U.S. citizens do not need a passport to go to Guam. A U.S. citizen can present a government-issued ID that is compliant with the regulations of the Transportation Security Administration when flying to the island.

To be more specific, the flight to Guam takes the same as a domestic flight to any other incorporated territory of the United States of America. Alongside places like the rest of the Northern Mariana Islands, American Samoa, and Puerto Rico. It means that a U.S. citizen doesn’t have to apply for a visa.

Among the acceptable documents a U.S. traveler can board a plane with are a U.S. passport book or card, a REAL ID, a state-issued ID, and an original or notarized copy of a birth certificate.

If you travel with a passport, ensure you have a compliant passport photo of 2×2 inches and with off-white background in your document. For example, it can be a passport photo from The UPS Store, a pharmacy that offers photo-taking services, or you can simply take a photo with an online tool yourself.

Please note the new rules of the Real ID Act came into action on May 3, 2023. A Real ID-compliant driver’s license, state-issued enhanced driver’s license, and the like have become obligatory to fly domestically within the U.S.

If you take a valid passport as proof of identification and citizenship when you fly to Guam, ensure it has at least one page spare.

Travelers that have no restrictions on entering Guam include:

  • U.S. citizens.
  • Lawful permanent residents and immigrants.
  • Crew staff.
  • Travelers under 18.
  • Diplomatic or foreign government representatives.

Please note:

If you have any doubts about a travel document in your particular situation,

it’s a safe solution to consult your local embassy or consulate in the U.S.

By doing so, you resolve all your concerns.
