Passports --For an up-to-date, country-by-country listing of passport requirements around the world, go to the "Foreign Entry Requirement" Web page of the U.S. State Department at http://travel.state.gov. International visitors can obtain a visa application at the same website.
Visas -- The U.S. State Department has a Visa Waiver Program allowing citizens of the following countries (at press time) to enter the United States without a visa for stays of up to 90 days: Andorra, Australia, Austria, Belgium, Brunei, Denmark, Finland, France, Germany, Iceland, Ireland, Italy, Japan, Liechtenstein, Luxembourg, Monaco, the Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom. Citizens of these nations need only a valid passport and a round-trip air or cruise ticket upon arrival. If they first enter the United States, they may also visit Mexico, Canada, Bermuda, and/or the Caribbean islands and return to the United States without a visa. Further information is available from any U.S. embassy or consulate. Canadian citizens may enter the United States without visas; they need only 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 United States, and (2) a tourist visa, which may be obtained without charge from any U.S. consulate.
Medical Requirements -- 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 United States. If you have a medical condition that requires syringe-administered medications, carry a valid signed prescription from your physician -- the Federal Aviation Administration (FAA) no longer allows airline passengers to pack syringes in their carry-on baggage without documented proof of medical need. If you have a disease that requires treatment with narcotics, you should also carry documented proof with you -- smuggling narcotics aboard a plane is a serious offense that carries severe penalties in the U.S.
For HIV-positive visitors, requirements for entering the United States are somewhat vague and change frequently. For up-to-the-minute information, contact AIDSinfo (tel. 800/448-0440 or 301/519-6616 outside the U.S.; www.aidsinfo.nih.gov) or the Gay Men's Health Crisis (tel. 212/367-1000; www.gmhc.org).
