Planning your first trip to the United States? America is vast, diverse, and full of surprises for newcomers. From the neon canyons of New York City to the wild landscapes of the national parks, the USA rewards travelers who come prepared. Wondering where is the most visited place in America? This USA travel guide covers 20 essential things first-time visitors need to know, from visas and tipping to transportation and cultural norms.
ENTRY REQUIREMENTS AND VISAS
1. Check Whether You Need a Visa or ESTA
Travelers from Visa Waiver Program countries need an approved ESTA before boarding, applied for at least 72 hours in advance. Everyone else needs a B-1/B-2 visitor visa from a US embassy, a process that can take weeks or months.
2. Your Passport Must Be Valid for Your Stay
The US doesn’t enforce the six-month validity rule for most nationalities, but your passport must be valid for the duration of your visit. Check the specific requirements for your country.
3. Have Proof of Onward Travel
Border officers may ask for your return ticket and hotel bookings. Have them accessible on your phone to make immigration smooth.
MONEY MATTERS
4. Tipping Is Expected, Not Optional
Tip 18 to 22 percent at restaurants, $1 to $2 per drink at bars, and 10 to 15 percent for taxis and rideshares. Service workers depend on tips because base wages are low.
5. Sales Tax Is Added at Checkout
Unlike many countries, US price tags don’t include sales tax. Expect 5 to 10 percent extra at the register, varying by state and city.
6. Credit Cards Are King
Cards are accepted nearly everywhere, including for small purchases. Bring a card with no foreign transaction fees, and carry some cash for tips and small vendors.
GETTING AROUND
7. America Is Built for Cars
Outside a few major cities, public transit is limited. Renting a car is the best way to explore national parks, small towns, and scenic routes. Book in advance for the best rates.
8. Distances Are Enormous
The US is the third-largest country in the world. Driving from New York to Los Angeles takes 40+ hours. Plan regional trips rather than trying to see everything at once. For trip ideas beyond the obvious, see the most unusual places to visit in the US.
9. Domestic Flights Are Affordable
Budget airlines make cross-country flights surprisingly cheap if booked in advance. Compare Southwest, JetBlue, and Alaska Airlines for the best domestic deals.
10. Rideshares Fill the Gaps
Uber and Lyft operate in most US cities and are often cheaper and more convenient than taxis, especially late at night.
CULTURE AND CUSTOMS
11. Americans Are Friendly and Chatty
Don’t be surprised when strangers strike up conversations. Small talk with cashiers, bartenders, and fellow travelers is a normal, welcome part of American culture.
12. Portions Are Huge
Restaurant servings are famously generous. Consider sharing entrees, and know that taking leftovers home in a box is completely normal.
13. Smoking and Drinking Laws Vary
The drinking age is 21 nationwide, and you’ll be carded. Smoking is banned in most indoor public spaces. Cannabis laws differ dramatically by state.
14. 911 Is the Emergency Number
For police, fire, or medical emergencies, dial 911 from any phone. It’s free and works even without a SIM card.
PRACTICAL TIPS
15. Get a Local SIM or eSIM
Staying connected is essential for maps and rideshares. eSIMs from providers like Airalo are cheap and activate instantly on arrival.
16. The US Uses Imperial Measurements
Distances are in miles, temperatures in Fahrenheit, and drinks in ounces. A quick conversion cheat sheet on your phone saves confusion.
17. National Parks Need Advance Planning
Popular parks like Yosemite, Arches, and Glacier now require timed-entry reservations. Book campsites and lodging months ahead for summer visits. See our best places to visit in USA summer for warm-weather trip ideas.
18. Weather Varies Wildly
The US spans tropical, desert, continental, and arctic climates. Check forecasts for each stop on your itinerary and pack layers.
19. Free Water and Restrooms
Tap water is safe to drink almost everywhere, and restaurants will give you free tap water on request. Public restrooms are common in cities and parks.
20. Healthcare Is Expensive: Get Insurance
A single ER visit can cost thousands of dollars. Comprehensive travel insurance with high medical coverage is absolutely essential for visiting the USA.
