Planning a trip to the United States involves more than booking a flight. Visitors usually need a handful of documents, a few practical items, and a realistic budget for fees. This guide covers what travellers typically carry and prepare for a trip to America: entry documents, money, health cover, electronics, and everyday essentials. It also explains the recent fee changes and common mistakes that cause delays at the airport. Rules change, so confirm the latest requirements with official government sources before you travel.
Quick Answer: What Do Most Travellers Carry?
Most visitors arrive with a valid passport, an approved travel authorisation or visa, a return ticket, proof of where they are staying, a credit or debit card, travel insurance, and a phone with a charger and adapter. Beyond those basics, the exact list depends on your nationality, how long you plan to stay, and what you will do once you arrive.
| Essential | Why you need it |
| Valid passport | Required for entry |
| ESTA or visa | Permission to travel to the US |
| Return or onward ticket | Shows you will leave |
| Accommodation details | Often asked at the border |
| Payment cards and some cash | Daily spending |
| Travel insurance | Healthcare can be costly |
| Phone, charger, adapter | Communication and navigation |
Passport
Your passport is the most important item. Make sure it is valid for your entire stay, and check whether your nationality has a six-month validity rule. Keep it in your carry-on bag, not in checked luggage, and take a photo or paper copy of the main page in case it is lost.
ESTA or Visa
Travellers from the 42 Visa Waiver Program countries do not need a traditional visa; they apply for an ESTA instead. The fee is $40.27 in 2026, and an approved ESTA is valid for two years or until the passport expires, whichever comes first. Stays are limited to 90 days per visit, and work or study is not allowed.
If your country is not on the list, you will need a B-1/B-2 visitor visa. The application fee is $185, and the new $250 visa integrity fee is charged on top when the visa is issued, bringing the total to about $435. ESTA travellers are exempt from the integrity fee. A visa also requires an interview at a US embassy or consulate, so apply early.
Proof of Return and Accommodation
Border officers can ask about the purpose of your trip, how long you will stay, and where you will sleep. Keep your return or onward flight details handy, along with your hotel booking or the address of the person you are visiting. Having these ready makes the process faster.
Money and Payment Cards
Credit and debit cards are accepted almost everywhere in America. Carry at least one card with no foreign transaction fee, and bring a backup card in case one is blocked. A small amount of cash is useful for tips, tolls, and small shops.
Tipping is part of the culture. Customers commonly leave about 15 to 20 percent at restaurants, and smaller tips for taxi drivers, hotel staff, and tour guides. Also remember that sales tax is added at the register and is not included in the shelf price, so your total will be higher than the price tag.
If you carry more than $10,000 in cash or equivalent monetary instruments, you must declare it to customs.
Travel Insurance
Healthcare in the United States is expensive for visitors, and a simple hospital visit can lead to a large bill. Most travellers buy travel insurance that covers medical treatment, emergency evacuation, and trip cancellation. Check what your policy includes, and carry the insurance number and emergency contact details.
Phone, Charger, and Adapter
The United States uses 120 volt electricity and flat two-pin or three-pin plugs, which may not match your devices. Bring a plug adapter and check whether your chargers support the voltage. For connectivity, consider an eSIM, a local prepaid SIM, or an international roaming plan, since public Wi-Fi is not always reliable.
Driving Licence and Transport
If you plan to drive, bring your home driving licence. Some travellers also carry an International Driving Permit, and some car rental companies prefer it. Remember that Americans drive on the right side of the road. Distances are long, so rental cars, domestic flights, and trains are common ways to travel. For domestic flights, a passport works as valid identification.
Medications and Health Items
Pack prescription medicines in their original containers, along with a doctor’s note or prescription copy if you can. Carry only what you need for the trip, and check whether any of your medicines are restricted in the US.
Clothing and Weather
America is huge and the climate varies. Winters in the north can be freezing, while the south and southwest can be extremely hot in summer. Pack layers, comfortable walking shoes, and weather-appropriate clothing for the places you plan to visit.
Customs and Food Rules
You will complete a customs declaration on arrival. Fresh fruit, meat, dairy, and plants are often restricted, so avoid bringing food from home unless you know it is allowed. Declare anything that might be questioned.
Common Mistakes to Avoid
- Forgetting to apply for ESTA before the flight.
- Using an unofficial website and paying extra fees.
- Travelling with a passport that expires too soon.
- Skipping travel insurance.
- Not carrying the right plug adapter.
