Citizens of 42 Visa Waiver Program (VWP) countries can visit the US for up to 90 days for tourism or business without a visa, but must first obtain an approved ESTA (Electronic System for Travel Authorization). All other nationalities must apply for a US visitor visa (B-1/B-2) at a US embassy or consulate.

VWP travellers with an ESTA may stay for up to 90 days per visit. This period is non-extendable. If you hold a B-2 tourist visa, the length of stay is determined by the CBP officer at the port of entry, typically up to 6 months.

A valid passport, valid ESTA approval or US visa, a completed Customs Declaration Form (CBP Form 6059B), and evidence of sufficient funds and a return or onward ticket. Biometric data (fingerprints and photo) is collected at the port of entry.

Visit the Grand Canyon, explore New York City's neighbourhoods, drive Pacific Coast Highway, hike in Yellowstone, experience New Orleans jazz and food, tour national parks in Utah, see the Smithsonian museums in Washington D.C., and catch a major league baseball or football game.

Travel insurance is very strongly recommended for the US. Healthcare costs are extremely high — a single hospital visit can cost thousands of dollars. The US has no universal public healthcare for foreign visitors.
