Language:

English is the official language, although many other languages are widely spoken in certain cities and communities. America has its own written US English spellings.

Passport and Visas:

•  Brits must have a full 10-year British Passport that's valid for six months after you return to the UK.
•  You will also need a USA visa or waiver form/ESTA. Apply for your ESTA at least 72 hours before travelling (http://esta.cbp.dhs.gov).

Voltage & Electricity:

The domestic electrical supply is 110V, 60 cycles AC. Sockets are for plugs with two flat pins.

Tipping:

Tipping is an established and accepted custom in America. For good service, waiters and taxi drivers expect 15-20%, and counter and bar staff 10-15%. Porters can expect from $3-$5 per case, while tour guides can be given the equivalent of £2-£3 per day.
