International travelers should expect a warm welcome to Arizona, though you will encounter some long lines and a little paperwork at immigration when entering the country. Citizens from most North American, European, and Latin American countries do not need a visa for stays up to 90 days. However, all international visitors, including Canadians, are required to show a valid passport. For more information about visas and requirements to enter the United States through the Visa Waiver Program, visit the U.S. State Department’s website at www.travel.state.gov .
Travelers exchanging foreign currency can do so at small kiosks inside the airport or at most banks. ATMs (automated teller machines) offer the best exchange rates, charging a $2 fee for the convenience. Be sure to inquire with your home bank to see if they charge an exchange fee, which usually ranges 1–2 percent. You’ll find ATMs at a host of locations, including banks, shopping centers, and gas stations. Also, almost all hotels, restaurants, and stores accept travelers checks from well-known institutions like American Express and Visa.
