The U.S. is large, complex, and diverse, with over 340 million people (2024) and distinct cultural and regional identities. Traveling the long distances between destinations can be time-consuming and expensive.
The United States has a strict and notoriously perplexing visa policy; nearly everyone needs a visa to visit the country, and obtaining an American visa of any kind can be a complicated and cumbersome affair.
Read up carefully before your visit, especially if you need to apply for a visa, and consult the Bureau of Consular Affairs. Travelers have been refused entry for many reasons, often trivial. During the application process, visitors to the U.S. are required to fully document mobile phone numbers, e-mail addresses and on-line identities they've used in the past five years.
Travelers under 18 years old may need a notarized letter of consent, preferably in English, from both their parents. If the border authorities aren't satisfied with this or with your travel plans and their documentation, you may get taken into the authorities' care for months until they can arrange your return.
New immigration practices were introduced in 2025 that resulted in the questionable detention of a few visitors with apparently valid travel documents at a port of entry. Detentions would last until the visitor departed on a flight back home. However, a few visitors have been detained for a few weeks before being allowed on a return flight. If you fear this problem (due to work permits, residing with an American spouse, problems on a prior visit or political opinions, for example), using an airport with pre-flight US Customs clearance airports would be safe: while you could still be denied en…

The size of the U.S. and the distance separating major cities make air the dominant mode of long-distance travel for short-term travellers. If you have time, or are travelling a short distance, travel by car, bus, or rail can be far more interesting. Long-distance car travel, in particular, is a quintessentially American way to see the country. That said, do not underestimate the size of the country and the time it takes to travel between cities. For comparison, the distance between New York City and San Francisco is greater than that between Lisbon and Moscow.
Gli Stati Uniti d'America (comunemente indicati come Stati Uniti, in inglese: United States of America o anche solo United States; in sigla USA) sono una repubblica federale dell'America settentrionale composta da cinquanta Stati e un distretto federale. I quarantotto stati contigui e il distretto di Washington (la capitale federale) occupano la fascia centrale dell'America settentrionale tra il Canada e il Messico e sono bagnati dall'oceano Atlantico a est e dall'oceano Pacifico a ovest. Con 9834000 km² in totale e circa 331 milioni di abitanti, gli Stati Uniti sono il terzo Paese al mondo per superficie e il terzo per popolazione. La geografia e il clima degli Stati Uniti sono estremamente vari, con deserti, pianure, foreste e montagne che sono anche sede di una grande varietà di fauna selvatica. È una delle nazioni più multietniche e multiculturali al mondo, prodotto di larga scala dell'immigrazione da molti Paesi. Sono dipendenti dagli Stati Uniti anche alcuni territori organizzati politicamente, i quali non fanno parte di alcuno Stato dell'Unione ma sono soggetti al solo Governo federale. Essi sono: Porto Rico, le Samoa Americane, le Isole Marianne Settentrionali, le Isole Vergini americane e Guam. Storicamente, i paleoamericani migrarono dall'Asia verso gli odierni Stati Uniti circa 12 000 anni fa. La colonizzazione europea cominciò invece intorno all'inizio del XVII secolo e venne per lo più dall'Inghilterra. Gli Stati Uniti d'America ebbero origine dalle tredici colonie britanniche situate lungo la costa atlantica. Le controversie tra la Gran Bretagna e le colonie sfociarono in un conflitto: il 4 luglio 1776 i delegati delle tredici colonie redassero e approvarono all'unanimità la dichiarazione di indipendenza, che diede ufficialmente vita a un nuovo Stato federale. La guerra d'indipendenza americana, conclusasi con il riconoscimento dell'indipendenza degli Stati Uniti dal Regno di Gran Bretagna, è stata la prima guerra per l'indipendenza da una potenza coloniale europea. La Costituzione fu adottata il 17 settembre 1787 e da allora è stata emendata ventisette volte. I primi dieci emendamenti, collettivamente denominati «Dichiarazione dei diritti» (Bill of Rights), furono ratificati nel 1791 e garantiscono diritti civili e libertà fondamentali. Gli Stati Uniti intrapresero una vigorosa espansione per tutto il XIX secolo, spinti dalla controversa dottrina del destino manifesto. L'acquisizione di nuovi territori e l'ammissione di nuovi Stati membri causarono anche numerose guerre con i popoli nativi. La guerra civile americana si concluse con l'abolizione della schiavitù negli Stati Uniti. Alla fine del XIX secolo gli Stati Uniti si estesero fino all'oceano Pacifico. La guerra ispano-americana e la prima guerra mondiale confermarono lo stato del Paese come potenza militare globale. Gli Stati Uniti uscirono dalla seconda guerra mondiale come una superpotenza globale, il primo Paese dotato di armi nucleari e come uno dei cinque membri permanenti del Consiglio di sicurezza delle Nazioni Unite. Dopo una grave crisi politica e sociale negli anni sessanta e settanta come conseguenza anche della sconfitta nella guerra del Vietnam, che sembrava minare il predominio mondiale statunitense, l'inattesa fine della guerra fredda e la dissoluzione dell'Unione Sovietica negli anni novanta hanno invece riconfermato il ruolo di superpotenza degli Stati Uniti. Gli Stati Uniti sono un Paese sviluppato, con una stima nel 2021 del prodotto interno lordo (PIL) di 22,68 migliaia di miliardi di dollari (circa il 25% del PIL mondiale a parità di potere di acquisto, a partire dal 2011). Il PIL pro capite degli Stati Uniti è stato il sesto più alto del mondo dal 2010, anche se la disparità di reddito del continente americano è stata anche classificata come la più alta all'interno dell'OCSE e i Paesi dalla Banca Mondiale. L'economia è alimentata da un'abbondanza di risorse naturali, numerose infrastrutture ed elevata produttività. Il paese rappresenta una forza politica guida del mondo occidentale, ed è la prima potenza economica e militare (suo è il 39% della spesa militare mondiale), posizionandosi al primo posto anche nel settore della ricerca scientifica e dell'innovazione tecnologica, ma presenta anche forti contraddizioni interne come uno Stato sociale più debole rispetto a molti altri Paesi sviluppati.

The United States is extraordinarily diverse in its array of attractions. You will never run out of things to see; even if you think you've exhausted what one place has to offer, the next destination is only a road trip away.
The Great American Road Trip (see above) is the most traditional way to see a variety of sights; just hop in the car and cruise down the Interstates, stopping at the convenient roadside hotels and restaurants as necessary, and stopping at every interesting tourist trap along the way, until you reach your destination.
Indescribably beautiful scenery, history that reads like a screenplay, entertainment options that can last you for days, and some of the world's greatest architectureno matter what your pleasure, you can find it almost anywhere you look in the United States.
American cuisine is far more than the bland McDonald's-and-Coca-Cola monolith that international stereotypes make it out to be. It's as diverse as the American people themselves, sporting regional variations between different parts of the country and incorporating localized versions of ethnic dishes from around the world. Each region's cuisine developed based on their immigrant heritage and availability of ingredients at hand.
The variety of restaurants throughout the U.S. is remarkable. In a major city such as New York, it may be possible to find a restaurant from nearly every country in the world. In addition to independent restaurants, the U.S. possesses a singularly baffling array of fast food and casual chain restaurants; the sheer variety domestically is immense.
You will want to experience the foods of the region you are visiting: seafood in the Pacific Northwest and New England, steak and Tex-Mex in Texas, Cal-Mex in California, Creole and Cajun in Louisiana, barbecue (BBQ) and fried chicken throughout the South and Texas with each region having its unique sauces and preparations. New Mexico has its own cuisine typified by salsa verde (green chili sauce), and other states in the Southwest serve lots of Mexican foods and often use chilis and chili-based rubs and sauces outside of specifically Mexican contexts.
Fresh food availability is particularly evident in California, where organic food and "slow food" are prominent. In Florida, you can tour the orange groves f…

Drinking customs in America are as varied as the backgrounds of its many people. In the cities, you can find many places to drink.
Bars of every shape and kind exist in the United States, including British/Irish pubs and Mexican cantinas, those that specialize in a particular spirit, and bars with themes ranging from 1980s nostalgia to video gaming.
In the suburbs, alcohol is mainly served in restaurants rather than bars. In rural areas, the line between "bar" and "restaurant" is often blurred to the point of meaninglessness; with few establishments nearby, locals go to the same place for both meals and nightlife. A few states have dry counties, places where it is illegal to sell alcohol for local consumption; these are mostly in rural areas.
It's generally wise to book ahead, directly with the provider when possible. In major cities, prices can vary wildly by season, if there are large conventions in town, etc.
Checking in almost always requires photo ID (driver's license or passport) and a credit or debit card matching the ID that will have a hold placed on it to cover any damages to the room. This applies even if you have prepaid for your stay online. It may take several days for the hold to clear after you check out.
By far the most common form of lodging in rural United States and along many Interstates is the motel. Providing inexpensive rooms to automotive travelers, most motels are clean and reasonable with a limited array of amenities: telephone, TV, bed, bathroom. Motel 6 () is a national chain with reasonable rates ($60–120, depending on the city). Super 8 Motels () provide reasonable accommodations throughout the country as well. Reservations are typically unnecessary, which is convenient since you don't have to arbitrarily interrupt a long road trip; you can simply drive until you're tired then find a room. Often they will also light up their sign outside to tell if there is vacancy, in which case you can simply walk in if they have one. However, some are used by adults looking to book a night for sex or illicit activities and many are located in undesirable areas.

Cultural norms vary significantly from region to region. In general, social etiquette tends to be more formal in the Northeast and the South, more casual on the West Coast, and somewhere between those two extremes in the Midwest.
