Guam Entry Requirements for US Travellers
Informational only — not insurance, financial, or medical advice. Coverage, exclusions, and limits vary by policy and insurer — read the full policy terms before buying. Entry rules can change; verify entry/visa rules and travel advisories on travel.state.gov (and passport-validity / entry requirements with the destination’s embassy) before you travel. Vaccination notes are generic CDC framing, not medical advice — check the CDC destination page and a clinician.
US citizens traveling to Guam do not require a visa, as Guam is a US territory. There is no State Department advisory level assigned to Guam. Passport validity requirements and onward-ticket documentation do not apply to US citizens traveling to US territory. Yellow fever vaccination is not required for travel to Guam, and there is no malaria risk in the region.
The CDC recommends that travelers ensure routine vaccinations are up to date before travel, including MMR, Tdap, polio, influenza, and COVID-19. These recommendations reflect general CDC framing and are not medical advice. All travelers should verify current entry requirements and health recommendations on travel.state.gov and the CDC's Guam destination page before departing, as requirements may change.
