Language: English is the most common language spoken but Spanish is often heard in the south-western states.
Entry requirements for Americans: US citizens require passports.
Entry requirements for UK nationals: UK nationals require a passport valid for duration of stay. Most passport holders can get an Electronic System for Travel Authorisation (ESTA) through the Visa Waiver Programme, which allows travel to the US for up to 90 days. The VWP includes tourism, certain types of business visit and transit to another country.
Entry requirements for Canadians: The most important requirement on entering the U.S. is providing proof of Canadian citizenship. A valid Canadian passport is the best document to prove Canadian citizenship and the right to return to Canada. However, several other documents can serve, depending on the mode of transport. Generally, Canadian citizens do not require visitor, business, transit or other visas to enter the United States from Canada, though there are some exceptions.
Entry requirements for Australians: Passports must be valid for the period of intended stay. If visiting the US for fewer than 90 days, Australian nationals may be eligible to apply for an Electronic System for Travel Authorization (ESTA), and enter under the Visa Waiver Program (VWP).
Entry requirements for South Africans: South Africans must hold a passport valid for duration of stay. A visa is required.
Entry requirements for New Zealanders: Passports must be valid for duration of stay. New Zealand nationals can get an Electronic System for Travel Authorisation (ESTA) under the Visa Waiver Programme for entry into the United States.
Entry requirements for Irish nationals: Passports must be valid for duration of stay. Irish nationals can get an Electronic System for Travel Authorisation (ESTA) under the Visa Waiver Programme for entry into the United States.
Passport/Visa Note: It is highly recommended that passports have at least six months validity remaining after your intended date of departure from your travel destination. Visa is required for short visits unless travelers qualify for entry under the Visa Waiver Program. The Visa Waiver Program (VWP) enables citizens of certain countries to travel to the US for a stay of up to 90 days without a visa. Visitors under the VWP need to register online three days before travel and have an Electronic System for Travel Authorization (ESTA). This allows the US government to screen all visitors before travel. Visitors entering the country under the VWP must have a machine-readable passport (MRP) that has a barcode on the photo page. Travellers under the VWP must have passports that include biometrics if they wish to enter the country without a visa, which means that passports must contain unique personal data such as fingerprints or iris details. All passports must contain a digital photo image in order to travel visa-free. All visitors to the USA have a photograph and two fingerprints taken by an inkless scanner on arrival, including those travelling visa-free under the VWP. As part of the Western Hemisphere Travel Initiative (WHTI), all travellers travelling between the United States and Canada, Mexico, Bermuda, and the Caribbean region are required to present a passport or other valid travel document to enter or re-enter the United States. If departing from the USA, a valid passport is required by immigration authorities. Immigration officials often apply different rules to those stated by travel agents and official sources.
Travel Health: There are no specific health risks associated with travel within the USA. Medical facilities are excellent, but expensive. Only emergencies are treated without prior payment and treatment can be refused without evidence of insurance or proof of funds. Good medical insurance is essential.
Tipping: A 15 percent tip is expected by taxi drivers, bartenders, hairdressers and waiters, but don't tip in fast-food or self-service restaurants. In expensive restaurants or for large parties, tip 20 percent of the bill. It is normal to tip staff such as valets and porters in hotels; this is discretionary, although a minimum of $5 is expected. Most services are customarily tipped if the service is good.
Safety Information: Travel within the United States is generally trouble-free, however, travellers should be aware that the US shares with the rest of the world, an increased threat from terrorist incidents. Security has been heightened, particularly at airports. Restrictions on hand luggage apply and travellers are advised to check on the latest situation with airlines in advance. Travellers should also be alert to the dangers of car and street crime in cities and should use common sense and take basic precautions. Hurricanes are common between June and November, putting the southern USA, including the Gulf Coast and the eastern US at risk. There is a risk of wildfires in many dry areas in the US, particularly on the West Coast from March to November.
Local Customs: Laws vary from state to state, including speed limit, fines and punishment. The age at which you may legally buy and consume alcohol is 21 years.
Business: In such a large country, filled with so many diverse groups, business practices may differ according to each state, however rarely to any large degree. The East Coast is traditionally more formal than the West Coast, however in states such as California dress code and conservative appearance are as common as they would be in New York. Punctuality is important throughout the country and it is considered rude to be late for a meeting. Gift-giving is uncommon as it may be construed as bribery. Appropriate titles (Mr, Mrs, Ms) are used upon introduction and until otherwise stated. Americans favour politeness and greetings of 'Hello' and 'How are you?' are often expressed with sincerity. Business hours may vary in each state, but an 8am start and 5pm finish Monday to Friday is the most common with an hour over lunch. Status and age are not necessarily indicative of seniority, nor do they carry much weight in themselves. Those doing business in the States should be mindful of this fact; never make assumptions about someone's position or rank. Best practice is to be respectful to all parties. That said, the US upholds a hierarchal business structure, in which 'the boss' is the ultimate decision-maker. Senior leaders have the power of the last word, and can go against the grain just as easily as they can follow popular opinion. Concentrate on winning over this individual, even if the greater group seems unsupportive. Americans value a direct style of communication. In this fast-paced, consumer culture 'time is money', and small-talk is viewed as unnecessary and wasteful. Get to the point quickly, speak about issues in a frank and open manner, and don't take offence if someone questions or challenges you outright.
Communications: The international country dialling code for the United States is +1. Mobile networks cover most of the country, especially all urban areas. Internet cafes are prevalent in most towns and cities and wifi is widely available.
Duty Free: Travellers to the United States who are returning residents of the country do not have to pay duty on articles purchased abroad to the value of $800 provided their stay was longer than 48 hours and their duty-free allowance was not used in the 30-day period prior. For passengers arriving from Samoa, Guam and the U.S. Virgin Islands, a duty-free allowance of $1,200 is allowed.
