Entry requirements

☐ Aliens entering the United States must obtain a visa from one of the U.S. diplomatic missions. Visitors may be exempt if they are citizens of one of the visa-exempt or Visa Waiver Program countries.

Practical

• ☐ Plug type A/B, 120V — bring an adapter if yours differs
• ☐ Drives on the right
• ☐ Emergency (police): 911
• ☐ Emergency (ambulance): 911
• ☐ Emergency (fire): 911
• ☐ SIM: The three largest mobile phone networks in the U.S. are AT&T, Verizon Wireless, and T-Mobile. These all have good coverage of practically all urban/suburban and many rural areas of the country, although each network has strong and weak areas. There are many mobile virtual network operators (MVNO) that rebrand service on the major carriers' networks.
• ☐ Money: The U.S. currency is the United States dollar ($), divided into 100 cents (¢). Foreign currencies are almost never accepted, though some major hotel chains may accept traveller's checks in other currencies. Some establishments close to the Canadian and Mexican borders accept their currencies, though usually at poor exchange rates. Japanese yen is sometimes accepted in Hawaii.
• ☐ Tipping: Tipping is widely practiced in the United States. Standards vary, but gratuities are always given to servers in restaurants and bars, taxi drivers, parking valets, and bellstaff in hotels. When traveling in the U.S., try to keep some $1 and $5 bills in your wallet for small tips.

Before you go

General trip-prep, not specific to United States — the same short list applies anywhere.

• ☐ Register with your embassy's traveler program if one exists
• ☐ Check your passport's validity and blank-page requirements on your destination's official entry-rules page
• ☐ Photograph/screenshot your passport, visa, and travel insurance documents
• ☐ Download offline maps for your destination
• ☐ Confirm your bank/card issuer knows you're traveling
• ☐ Check whether your phone plan needs a travel add-on or a local SIM
