Visa & Entry

Guam is an unincorporated US territory. US citizens travel to Guam with the same freedom as traveling between US states. No passport is needed. A valid government-issued photo ID (driver's license or state ID) is sufficient for travel between the US mainland and Guam. There are no immigration or customs formalities for domestic travelers. You clear no border checkpoint on arrival at Antonio B. Won Pat International Airport (GUM).

Guam uses US currency, US federal law, and the US Postal Service. Your US health insurance, driver's license, and cell phone plan work here (confirm with your carrier about roaming in US territories). Military bases cover about 27% of the island: Naval Base Guam and Andersen Air Force Base are major Pacific installations. The Chamorro people are the indigenous population, and Chamorro cultural sites, language, and food are central to the island's identity.

Direct flights from Honolulu to Guam run about 7 hours 30 minutes on United. From the US mainland, connect through Honolulu or fly United's route from select hubs. Guam is also a major hub for flights to and from Asia: Tokyo (3 hours 30 minutes), Seoul (4 hours), and Manila (3 hours 45 minutes) have frequent service. Guam sits in the Chamorro Standard Time zone (ChST), UTC+10, which is 15 hours ahead of US Eastern Time. The island is 30 miles long and 4 to 12 miles wide. Tumon Bay is the main tourist and hotel district. Rental cars are the primary transport: rates start at $30 per day.
