First-Time Visitor's Guide to the USA: What You Need to Know

The USA is the world’s third-largest country by area and covers six time zones, so “visiting the USA” can mean almost anything—a week in New York, a road trip through the Southwest, two weeks island-hopping in Hawaii. This guide covers what every first-time visitor needs to know regardless of which corner of the country you’re heading to.

Entry Requirements

Most visitors from Europe, Australia, Japan, South Korea, and 35 other countries can enter without a visa under the Visa Waiver Program (VWP). You must apply for ESTA (Electronic System for Travel Authorization) online at esta.cbp.dhs.gov before departure. The fee is $21, authorization is valid for two years or until your passport expires, and allows stays of up to 90 days per visit. Apply at least 72 hours before flying—most approvals come through within minutes, but some take longer.

If your country is not on the VWP list (India, China, most of South America, and most of Africa are not), you need a B-2 tourist visa. Apply at travel.state.gov and book an interview at your nearest US Embassy. Processing times and visa fees vary by country—budget $185 for the application fee and anywhere from two weeks to several months for the interview appointment.

All visitors need a valid passport with at least six months’ validity beyond their planned departure date.

Arriving: Which Airport?

The USA has more than 500 commercial airports. The busiest international gateways are:

• JFK (New York) — largest hub for transatlantic flights; plan for 60–90 minutes in immigration queues during peak hours
• LAX (Los Angeles) — primary West Coast gateway; notoriously slow customs in Terminal B
• ORD (Chicago O’Hare) — central hub, useful for onward domestic connections
• MIA (Miami) — main gateway for South America and the Caribbean
• ATL (Atlanta) — busiest airport in the world by passenger count; good connection hub

Mobile Passport Control (via the CBP One app) or Global Entry ($100, five-year membership) can cut immigration time to under 10 minutes. Standard queues at major airports can run 45–90 minutes.

Getting Around

The USA has almost no inter-city rail worth relying on outside the Northeast Corridor (Boston–New York–Washington DC). For most trips, your realistic options are flying or driving.

Domestic flights are cheap and frequent. Fares between major cities often run $60–150 one-way when booked 3–6 weeks ahead. Southwest, Delta, United, and American cover most routes; budget carriers Spirit and Frontier go lower but charge for everything including carry-on bags.

Car rental is essential outside major cities. Rates start around $40–70/day for a compact car; add collision damage waiver (CDW) if your credit card doesn’t cover it. In the USA, many premium credit cards (Chase Sapphire, Amex Gold) provide primary or secondary rental car coverage—check your policy before paying for the rental company’s insurance.

Public transit is excellent in New York, Boston, Chicago, San Francisco, and Washington DC. It is limited to useless in Los Angeles, Phoenix, Houston, and most of the South and Midwest.

Uber and Lyft operate in virtually every city and most smaller towns. Rideshare is generally reliable and affordable for short trips.

Budget Expectations

The USA is a mid-to-high cost destination. A realistic daily budget:

• Budget traveller: $100–130/day — hostel dorm ($30–50), fast food and grocery meals, public transit, free attractions
• Mid-range: $180–250/day — private hotel room ($120–180), sit-down meals, one paid attraction
• Comfortable: $300–500/day — 3-star hotel, restaurant dinners, car rental, museum entry

New York, San Francisco, and Honolulu cost noticeably more than the national average. Nashville, New Orleans, and most of the Southeast and Midwest run cheaper.

Tipping Culture

Tipping is not optional in the USA—it is the primary component of service workers’ wages. Failing to tip is considered rude and, in most states, servers are legally paid as little as $2.13/hour with the expectation that tips make up the difference.

Standard rates:

• Restaurants: 18–20% of the pre-tax bill, 25% for excellent service
• Bars: $1–2 per drink, or 15–20% on a tab
• Taxis and rideshare: 15–20%
• Hotel housekeeping: $2–5/night, left in the room daily
• Hotel concierge/porter: $2–5 per bag

Most point-of-sale terminals now prompt for a tip percentage. At coffee shops and counter-service restaurants, tipping is discretionary but common (10–15%).

Payment Methods

Visa and Mastercard are accepted almost everywhere. American Express is widely accepted in cities but occasionally refused at smaller businesses and gas stations. Cash is rarely necessary—most transactions in the USA are card-based. Carry $40–60 in small bills for tips, parking meters, and the rare cash-only food stall.

Notify your bank before travel to avoid fraud blocks. Many US ATMs charge $3–5 withdrawal fees on top of your bank’s foreign transaction fee. Charles Schwab and Wise both offer fee-free international ATM withdrawals.

Phone and SIM Cards

US carriers use GSM and 5G networks compatible with most modern unlocked phones. The easiest tourist option is T-Mobile’s Visitor Plan ($30 for 10GB/5 days or $50 for 25GB/21 days), available at T-Mobile stores including at major airports. AT&T and Verizon offer visitor SIMs at comparable prices.

For eSIM users, Holafly and Airalo both offer USA data plans from approximately $25 for 10GB, delivered instantly to your phone. Coverage in rural areas—especially in the Mountain West—can be patchy regardless of carrier; Verizon generally has the best rural reach.

Driving in the USA

Americans drive on the right. Speed limits are posted in miles per hour (mph): 25–35 mph in cities, 55–65 mph on highways, 70–80 mph on interstate freeways in western states. Most rental cars are automatic transmission.

You can drive in the USA on your home country’s driving licence for up to one year in most states. An International Driving Permit (IDP) is not legally required in most states but is a useful translation document.

Gas (petrol) is sold by the gallon (1 US gallon = 3.78 litres). Prices as of 2026 average around $3.20–4.50/gallon depending on the state—California is consistently the most expensive.

Healthcare

The USA has no universal healthcare system. A routine doctor’s visit costs $150–300 without insurance; an emergency room visit for a minor issue can cost $1,500–5,000; a hospital admission for a serious illness can run $30,000–100,000. Travel insurance with a minimum of $500,000 medical coverage is not optional—it is essential.

In a medical emergency, call 911. Urgent Care clinics (not emergency rooms) handle non-life-threatening issues at lower cost—a typical urgent care visit runs $150–250 without insurance.

Safety Basics

The USA is generally safe for tourists in well-trafficked areas. Standard urban awareness applies: be conscious of your surroundings at night, keep valuables out of sight in parked cars (smash-and-grab theft is common in San Francisco and some other cities), and research neighborhood safety before booking accommodation in unfamiliar areas.

Emergency number for police, fire, and ambulance: 911.

Time Zones

The continental USA spans four time zones:

• Eastern (ET): New York, Miami, Atlanta
• Central (CT): Chicago, Nashville, New Orleans
• Mountain (MT): Denver, Phoenix, Salt Lake City
• Pacific (PT): Los Angeles, Seattle, San Francisco

Hawaii is Hawaii-Aleutian time (UTC-10), and Alaska has its own zone (UTC-9). Factor in time differences when booking domestic flights—a 6am departure from Los Angeles is 9am Eastern.
