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.
美利堅合眾國(英語:The United States of America、U.S.A.、 United States、U.S.),简称美国(America、USA和US),是北美洲的一个聯邦制共和國,亦是當今世上唯一的超級強國。美國由下轄的50個州加上联邦政府直辖的华盛顿哥伦比亚特区、五個离岸自治領土及若干外島組成。美国的官方领土面积為9,372,610平方公里(3,618,780平方英里),为北美第二(次于加拿大),并位居世界第三或第四。截至2020年初,美国总人口約為3.3億人,世界第三人口大国、人口最多的发达国家。美国有着來自世界各地的大量移民,是世界上民族和文化最多元的國家之一,有“民族大熔炉”之称。美國国土的地形与气候複雜多样,生物多样性齐全,是多种野生动植物的主要家园。 欧洲人从16世纪开始殖民北美,而现今的合众国起始于东海岸的13个英属美洲殖民地。七年战争后,大不列顛王國与其海外殖民地之间的矛盾愈发剧烈,1775年美国革命爆发,1776年7月4日,正与大不列颠进行独立战争的各殖民地派出代表,协同一致發表《独立宣言》。1783年大不列顛王國承认這13個北美殖民地脫離管辖而独立,与其簽訂《巴黎條約》,戰爭終止。这场战争也是第一场成功脱离欧洲殖民帝国的独立战争。1781年,《邦联条例》在邦聯13個構成州获得通过,共同组成邦聯議會,各實體組成國家聯盟,1787年《美利堅合眾國憲法》完稿,合併一國後將邦聯體制升級為聯邦,「美利堅合眾國」联邦政府随之成立。1791年,合称为权利法案的十条宪法修正案獲得批准,担保基本民权。 自19世紀起美國從獨立时的英裔殖民地國家開始轉向西进和對外擴張,美國聯邦政府先后通过1803年和1819年两次购地、与英属殖民地谈判、击败墨西哥和屠杀并强行迁移原住民等方法获得北纬49度线以南、格兰德河中游以北的几乎所有土地,并从俄羅斯帝國手中购得阿拉斯加。这期間陸續有許多新建立的殖民地政体申請加入美国聯邦,随着逐渐不断地承认扩张领地为新州份,至1848年时美国疆域已横跨整个北美大陆。19世纪下半叶,美国南部七个蓄奴州宣布退出聯邦獨立成立美利坚邦联国,因而爆发內戰,後來被林肯领导的联邦政府以武力重新併吞,终结曾在南方诸州合法的奴隶制度。19世纪末,美国将其领土主权延伸到太平洋的夏威夷,并在第二次工业革命的推动下开始镀金时代和进步时代的蓬勃发展期。随后美西战争的胜利,美国對外干涉的範圍超過現在的美國本土,使美国势力进入加勒比海地区及西太平洋。 进入20世纪后,美国在第一次世界大戰后期参战并奠定其作为一个全球性军事力量的基础。咆哮的二十年代结束后,美国在1930年代迎来經濟大蕭條,在第二次世界大戰獲得勝利之后美国迅速崛起成为超级大国。作为联合国安全理事会五个常任理事国之一,美國不僅是核武擁有國,亦是世界上第一个研发出核武器,並唯一曾将其投入实战的国家。二战后美国与苏联因意识形态和地缘政治竞争进行數十年的冷戰,在对峙顶峰时期的太空竞赛亦促使人类第一次登月计划的成功。20世紀90年代初苏联解体后,美國被廣泛視為當今世上唯一的超級強國。 美国自19世紀末开始就已成为世界第一大经济体,長期以來都是全球的經濟、軍事、教育、科研、航天及醫療技術的頭號強國。美国作为高度发达的资本主义国家,是世界上最大的進口國及第二大的商品出口國,國內生產总值按國際匯率排名世界第一、而依購買力平均則位列第二。在国民平均薪資、人類發展指數、人均國内生產總值以及人均生產力等社会经济学表现指标上,美国均处于世界领先地位。美国经济已步入后工业时代,服务行业占据经济主导地位,位列世界第一。同时,其生产制造业规模也極為龐大,位居於世界第二。僅占據全世界4.4%人口的美國貢獻了世界四分之一的國内生產總值和三分之一的全球軍事開支,這使其在經濟和軍事上均處於全世界最重要的地位。美国在政治和文化上是一支世界显著並影響深遠的力量,也在科学研究和技术创新上占据世界领导地位。

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.
