What do I need to bring to the United States for free travel?

1, passport and other basic documents are necessary, so you should take them with you to avoid losing them.

2, mainly international credit cards, which can be used for eating and shopping. Look at the itinerary in cash, don't bring too much.

3. Always keep cold medicine, motion sickness medicine, digestive medicine, antidiarrheal medicine, essential balm and other medicines. But pay attention to the right amount, otherwise it will be easily confiscated by the customs.

4, all kinds of snacks. Puffed food, melon seeds, hawthorn slices, candied fruit, shredded squid, dried bean curd, pickled mustard tuber, etc. In case you can't find a good supermarket in China in the United States, you can bring more in China. Be careful not to bring sausages and other meat products, the customs will check!

5. Open international roaming before the mobile phone goes abroad, handle related business, and avoid unnecessary expenses.

6. Change the plug. Although many hotel sockets and porcelain plugs can be used directly, just in case.

7. Windproof clothes and clothes that are easy to dry. It is cool in San Francisco in the morning and evening, and it may be cooler in some parts of the eastern United States, depending on the weather forecast.

8, sunglasses, sunscreen, hats and other sunscreen products. Las Vegas is very hot, the Grand Canyon and other places are hot and sunny, so pay attention to sun protection. Of course, umbrellas and disposable raincoats are also needed.

9. Skin care products, personal toiletries, slippers and towels. American hotels may not have disposable toiletries. Meixi is relatively dry, so we should also pay attention to moisturizing.

Precautions:

1, the United States is an immigrant country with high tolerance and no special taboos. However, laws and regulations are not the same among states in the United States. If you are traveling freely, you should pay attention to the local rules.

2. American police always patrol around by car when they are on duty, so please obey the traffic rules even in places where people and cars are scarce. Pedestrians who jaywalk may be fined by the police 100 USD.

American police are armed with guns, so don't mess with them. If communication is difficult, you can tell them "I can't speak English".

Smoking is not allowed in government buildings, transportation, public places and most indoor places.

Practical mobile APP

1, Weather Software-Weather Channel: It is very useful. It can be added that many cities can see the hourly weather conditions in the next ten days, such as the sunrise and sunset of precipitation, the spread of pollen/tree powder/grass powder, and the average airport delay.

2. Real-time map-Google Maps: Generally, the first route searched out is basically the best, although sometimes it is not the shortest, but it is often the fastest. You can check the traffic situation and avoid the toll road, but the price of taking the path is often painful. You can also check the bus and subway (guide the route, but time and frequency are often not allowed).

3. Taxi software: It is convenient and fast, without complicated telephone/address/long waiting/expensive, similar to QQ taxi, credit card binding and automatic payment. There is no need to give cash or tips during the whole taxi ride.
