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 United States 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 www.getyouhome.gov for details). Children 15 and under may continue entering with only a U.S. birth certificate or other proof of U.S. citizenship.
It is always advised to have at least one or two consecutive blank pages in your passport to allow space for visas and stamps that need to appear together. It is also important to note when your passport expires: Many countries require your passport to have at least 6 months left before its expiration in order to allow you into the destination.

The U.S. State Department has a Visa Waiver Program (VWP) allowing citizens of the following countries to enter the United States without a visa for stays of up to 90 days: Andorra, Australia, Austria, Belgium, Brunei, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, the Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, and the United Kingdom. (This list was accurate at press time; for the most up-to-date list of countries in the VWP, consult http://travel.state.gov/visa.) 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 US$14 fee for the online application. Existing ESTA registrations remain valid through their expiration dates. Note: Any passport issued on or after October 26, 2006, by a VWP country must be an e-Passport for VWP travelers to be eligible to enter the U.S. without a visa. 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. If your passport doesn't have this feature, you can still travel without a visa if the valid passport was issued before October 26, 2005, and includes a machine-readable zone; or if the valid passport was issued between October 26, 2005, and October 25, 2006, and includes a digital photograph. For more information, go to http://travel.state.gov/visa. 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.
