Quick answer: Most leisure travelers from Visa Waiver Program countries can enter the U.S. for up to 90 days using an ESTA instead of a visa, but everyone else needs a B-1/B-2 visitor visa arranged in advance — always verify your specific requirement on the official CBP/State Department sites before booking, since eligibility rules have tightened in 2026.
Visa & entry
If you hold a passport from one of the roughly 42 Visa Waiver Program (VWP) countries — including the UK, most of the EU, Australia, New Zealand, Japan, South Korea, Singapore, Taiwan, Chile, and Qatar — you generally may travel to the United States for business or tourism for stays of up to 90 days without a visa, provided you obtain approval through ESTA. The Visa Waiver Program enables most citizens or nationals of participating countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa, but travelers must have a valid ESTA approval prior to travel. Apply through the official esta.cbp.dhs.gov portal — CBP recommends that travelers apply for ESTA as soon as they begin planning their trip and no later than 72 hours before departure. Note that Visa Waiver Program requirements include a passport with a machine-readable zone and an electronic passport containing biometric information.
Important exceptions apply: travelers who have traveled to or been present in North Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011, or in Cuba on or after January 12, 2021, are generally no longer eligible for the VWP and must apply for a regular visitor visa instead. Entry rules changed again in 2026 — on January 1, 2026, the specific countries whose nationals are subject to entry limitations in the U.S. were updated per a proclamation restricting entry of certain foreign nationals, though Canadian citizens are not subject to these limitations.
If your country isn’t in the VWP, you’ll need a B-1/B-2 visitor visa, which involves filling out the DS-160 form, paying the fee, attending an in-person interview at a US embassy or consulate, and submitting the required documents. Remember that even with an approved ESTA or visa, authorization does not determine whether a traveler is admissible — U.S. Customs and Border Protection officers determine admissibility upon arrival.
Because rules, fees, and country lists change without much notice, always confirm your specific situation directly on esta.cbp.dhs.gov and travel.state.gov before booking flights.
Getting around
The U.S. is enormous, and infrastructure varies sharply by region. Outside of major cities like New York, Washington D.C., and Chicago, public transport is limited, and renting a car is often the best way to explore. Don’t underestimate distances — a drive from Los Angeles to San Francisco takes about 6-7 hours, while New York to Los Angeles would take 4-5 days by car, so plan on domestic flights for cross-country trips.
For intercity rail, Amtrak connects most major cities, and its USA Rail Pass lets you take 10 rides over 30 days to more than 500 destinations for a single fixed price. For identification, note that a REAL ID is required for domestic air travel but not for Amtrak train travel, since Amtrak does not check ID for standard boarding (though passengers 15+ may need to show a valid passport or other photo ID when purchasing tickets, checking baggage, or if asked onboard). International visitors flying domestically simply use their passport as ID.
In cities, many urban transport networks accept contactless payments or travel passes for convenient access to multiple journeys at discounted rates — tap-to-pay bank cards now work directly on subway/bus systems in New York, Chicago, Washington D.C., and other major hubs, eliminating the need for paper tickets. Rideshare apps (Uber, Lyft) and taxis are widely available in cities, while rural areas and national parks may require a rental car.
Money & costs
The local currency is the US Dollar (USD). You can exchange money at banks, currency exchange offices, or withdraw USD from ATMs, which are widely available in cities and airports. Credit and debit cards are accepted almost everywhere, though it’s wise to carry a little cash for small purchases, tips, or in rural areas where card facilities can be limited. Visa and Mastercard are the most widely used networks; foreign cards may incur a foreign transaction fee, so check with your bank beforehand.
A key budgeting point: prices are usually shown before sales tax, which varies by state and city (often 5-10%) and is added at checkout. Tipping is deeply embedded in American service culture — expect to tip 15-20% at sit-down restaurants (on the pre-tax bill), $1-2 per drink at a bar, $2-5 per day for hotel housekeeping, and 10-15% for taxis or rideshares. Build in extra budget for these hidden costs, as sales tax, resort fees, tipping, and parking are expenses international visitors often underestimate.
Best time to visit
The U.S. spans multiple climate zones, so timing depends heavily on where you’re headed. As a general rule, spring (March to May) and autumn (September to November) offer comfortable weather and fewer crowds across most of the country. Summer (June–August) is high season with peak prices and warm-to-hot weather nationwide — ideal for beaches and national parks, but expect large crowds at major attractions, so book well ahead. December to February (excluding the holidays) is generally the cheapest and least crowded time to travel, though parts of the country see cold, snowy winters while others (Florida, Arizona, Southern California) stay mild and sunny.
Regional nuance matters: the Atlantic hurricane season officially runs June 1 – November 30, with peak activity August through October, and NOAA data shows this period accounts for the majority of major hurricanes affecting the Southeast — factor this in if visiting Florida, the Gulf Coast, or the Carolinas. Fall foliage in New England peaks in late September/October, while desert regions like Arizona are best avoided in peak summer due to extreme heat.
Emergencies & safety
For any police, fire, or medical emergency, dial 911 (or 112, which redirects to 911). Emergency dispatch operates nationwide, and multilingual support is generally available in major metropolitan areas. Australia’s official travel advisory currently rates the U.S. at its lowest risk tier, advising travelers to exercise normal safety precautions, with a travel advice level of GREEN.
That said, entry screening remains strict — US authorities have broad powers to decide if you’re eligible to enter and may determine you are inadmissible for any reason under US law, so carry all supporting documents (return ticket, proof of funds, accommodation details). The UK’s official guidance also advises practical precautions: don’t leave passports in rental cars, especially not in the boot, since gangs may target vehicles driven by people who look like tourists, and while viol
