Entry notice: \ x0d \ x0d \ According to the immigration laws of the United States, all persons entering the country from land ports, airport ports or seaports in the United States are subject to inspection. If you fly to the United States, the flight attendant will give you an I-94 form, that is, an arrival/departure record, which records the personal information of immigrants and their addresses in the United States. \ x0d \ x0d \ There are four main inspection items at entry ports in the United States: \ x0d \ x0d \ 1, public health; 2.

If allowed to enter the country, the immigration officer will stamp the I-94 form of the entrant, and indicate the date of entry, visa status and length of stay in the United States. \x0d\\x0d\ It should be noted that holding a valid American visa does not guarantee entry, and the immigration officer at the American port finally decides whether to allow you to enter the country. The I-94 form approved by the port immigration officer is the proof of legal entry into the United States and needs to be properly kept. If it is lost or damaged, you should report it to the nearby immigrants in time and apply for a replacement. Form I-94 should be returned to the port immigration officer when leaving the United States. \x0d\ Passport must be valid for more than six months beyond the scheduled stay in the United States. \x0d\\x0d\2。 Safety regulations \ x0d \ x0d \ In order to improve passenger safety, the United States has restrictions on carrying liquids, sprays and hairspray on inbound and outbound flights.

Therefore, tourists do not need to deposit US dollars before going abroad, but only need to deposit enough RMB.

Free travellers should pay attention to the differences of traffic regulations in different places. \x0d\ American police 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. \x0d\\x0d\ Because the American police are equipped with guns, if you need to communicate with the police, please try to follow the instructions in front of them, and don't make any sudden movements, especially don't suddenly reach into the inside pocket of your coat to get something, so as to avoid misunderstanding. If you hear "freeze" or "stop" asking you to stop immediately, please do it. If you have communication difficulties, you can tell the police "I can't speak English" and they will try their best to solve it. \ x0d \ x0d \ Another thing to note is that smoking is not allowed in government buildings, most vehicles, public places and most indoor places. Many non-smoking hotels are equipped with testing equipment. \ x0d \ x0d \ If you accidentally hit someone, say "I'm sorry"; Ask others to make way and say "I'm sorry"; Don't smoke in public places. Before smoking in other places, ask people around you, "May I smoke?" ; Follow the western habit of "ladies first" and let the ladies go first; Say "hi" first when greeting people. \ x0d \ x0d \ Top Ten Points for Attention in American Tourism: Shopping and Tax Refund \ x0d \ x0d \ There are differences between urban areas and suburbs in major American cities.

It is very lively during the day, but at night, these areas are sparsely populated and unsafe. Business organizations usually work from 9 am to 5 pm from Monday to Friday. Shops in the city center usually close from 5 pm to 6 pm. \ x0d \ x0d \ suburbs are residential areas where most Americans live. Most people do their daily shopping in suburban shopping centers.

Banks, credit card companies, gasoline companies and department stores, and even some public utility companies and automobile manufacturers issue credit cards for people to use when shopping. \ x0d \ x0d \ The United States does not collect federal consumption tax, so there is no national tax refund system. States and cities will levy state and local taxes, with tax rates ranging from 0% to 9%. The more prosperous the city, the higher the tax rate. For example, the tax rates in new york, Los Angeles and San Francisco are all around 8.5-9%. On the contrary, there is no state consumption tax for shopping in Alaska, Delaware, Montana, New Hampshire and Oregon. The prices of goods marked in the United States are tax-free.
