Virtually every air traveler entering the U.S. is required to show a passport. All persons, including U.S. citizens, traveling by air between the U.S. and Canada, Mexico, Central and South America, the Caribbean, and Bermuda are required to present a valid passport. Note: U.S. and Canadian citizens entering the U.S. at land and sea ports of entry from within the Western Hemisphere must now also present a passport or other documents compliant with the Western Hemisphere Travel Initiative (WHTI; visit https://www.cbp.gov/travel/us-citizens/western-hemisphere-travel-initiative for details). Children 15 and under may continue entering with only a U.S. birth certificate, or other proof of U.S. citizenship.
To obtain a passport, contact a passport office in your home country.
The U.S. Department of State has a Visa Waiver Program (VWP) allowing citizens of the following countries to enter the U.S. without a visa for stays of up to 90 days: Andorra, Australia, Austria, Belgium, Brunei, Chile, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Taiwan, and the United Kingdom. (Note: This list was accurate at press time; for the most up-to-date list of countries in the VWP, consult https://travel.state.gov.) Even though a visa isn’t necessary, in an effort to help U.S. officials check travelers against terror watch lists before they arrive at U.S. borders, visitors from VWP countries must register online through the Electronic System for Travel Authorization (ESTA) before boarding a plane or a boat to the U.S. Travelers must complete an electronic application, providing basic personal and travel eligibility information. The Department of Homeland Security recommends filling out the form at least 3 days before traveling. Authorizations will be valid for up to 2 years or until the traveler’s passport expires, whichever comes first. Currently, there is a $14 fee for the online application. Existing ESTA registrations remain valid through their expiration dates. Note: As of April 1, 2016, you must have an enhanced e-passport to qualify for the VWP. Citizens of these nations also need to present a round-trip air or cruise ticket upon arrival. E-Passports contain computer chips capable of storing biometric information, such as the required digital photograph of the holder. Canadian citizens may enter the U.S. without visas, but will need to show passports and proof of residence.
Citizens of all other countries must have (1) a valid passport that expires at least 6 months later than the scheduled end of their visit to the U.S.; and (2) a tourist visa.
International visitors may carry in or out up to $10,000 in U.S. or foreign currency with no formalities; larger sums must be declared to U.S. Customs and Border Protection on entering or leaving, which includes filing form FinCen105. For details regarding U.S. Customs and Border Protection, consult your nearest U.S. embassy or consulate, or U.S. Customs and Border Protection (www.cbp.gov).
Unless you're arriving from an area known to be suffering from an epidemic (particularly cholera or yellow fever), inoculations or vaccinations are not required for entry into the U.S.
