United States 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 and nationals do not require a visa to enter the United States, as it is their home country or territory of citizenship. There is no State Department travel advisory level assigned to domestic travel. Passport validity requirements, onward ticket documentation, and yellow fever vaccination requirements do not apply to US domestic travel, since entry rules are governed by citizenship status rather than foreign entry protocols.
The CDC recommends that travelers ensure routine vaccinations are up to date before any trip, including MMR, Tdap, polio, influenza, and COVID-19. The United States has no malaria risk and no destination-specific vaccination requirements for US citizens traveling domestically. Travelers should verify current health recommendations on the CDC destination page and consult travel.state.gov for any updated guidance before departure.
