What is the time difference between the United States and China?

The time difference between the United States and China is 12-13 hours.

1, the United States implements daylight saving time, and Beijing time is just ahead of the eastern United States 12 hours (E.T. for short). In non-daylight saving time, Beijing time is earlier than Eastern Time 13 hours.

2. Subtract the standard time of two time zones (real-time area code) to be the time difference, and the time zone with larger value is earlier. The United States adopts daylight saving time 1 1 from the second Sunday in March to the first Sunday in June, and daylight saving time is one hour faster than normal time.

A note of American tourism: preparation

1. Most hotels in the United States do not provide toothbrushes, toothpaste, slippers and other related toiletries. Please prepare yourself.

Please bring appropriate clothes, especially comfortable, light and casual clothes. Please take a coat in summer in case it gets cold at night. It is very cold in winter in the eastern United States. Please keep warm. In addition, because the sunshine in the United States is very strong, umbrellas, sun hats, sunglasses and sunscreen lotion can be prepared, so pay attention to sun protection.

Because American Customs has strict restrictions and regulations on the entry of agricultural products, please pay attention when preparing food. Do not bring fresh or preserved animal and plant products such as meat, eggs, vegetables and fruits into the country. If you bring any food, you must declare it. If you bring any food, it is recommended to tell the tour leader before entering the customs for reference.

4. If you have first aid medicine for travel, please use parcel tape as far as possible, preferably with English name, and store it uniformly. I suggest you inform the tour leader for reference before entering the customs.

The second thing to pay attention to in American tourism: entry and exit

1. Entry Notes:

According to the immigration law of the United States, all people who enter 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/DepartureRecord, which records the personal information of immigrants and their addresses in the United States.

There are four main inspection items at American ports of entry:

1, public health; 2. Immigration status; 3. Customs inspection; 4. Agricultural inspection.

These four inspections can be conducted by one official or several officials.

On the way to the United States, flight attendants will distribute the I-94 form to passengers for everyone to fill out. Passengers fill in the basic personal information and address in the United States on this form.

At the port of entry, the immigration officer will check the documents and valid visas held by immigrants and examine the reasons for going to the United States, and decide whether to allow the inspected to enter the country and how long they can stay in the United States. 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.

It should be noted that holding a valid American visa does not guarantee entry, and ultimately it is up to the immigration officials at American ports to decide 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.

Passports must be valid for more than six months beyond the scheduled stay in the United States.

2, safety regulations

In order to improve the safety of passengers, the United States has restrictions on liquids, sprays and hairspray carried by inbound and outbound flights. These regulations are necessary to protect you from the threat of liquid explosion.

The size of liquid, spray or hair spray container in hand luggage must be equal to or less than 100 ml. All containers must be sealed in a transparent plastic bag with a capacity of one liter, and each person is limited to one plastic bag. Passengers are allowed to use self-sealing bags with a capacity of 1 liter or less.

Prescription drugs can still pass the security check. Passengers can bring baby products and prescription drugs that need to be used on the flight, but you may need to show proof of demand.

When you arrive at the security checkpoint, you must hand over any liquids, sprays and hairspray you still carry with you, including duty-free goods. The new regulations will also increase random body searches during security inspection.

Please prepare a plastic bag before check-in so that you have time to put the oversized container in the check-in baggage.
