How to go through the customs formalities when attending a child's graduation ceremony in Chicago?

On the flight to the United States, fill out the "US Customs Declaration Form" in English. This kind of "customs declaration form" is sometimes issued on the plane, and sometimes at the check-in counter to pick up the boarding pass and check the luggage. There is a Chinese version, but it is only marked in Chinese and must be filled in English.

At Chicago O 'Hare International Airport:

I. Entry formalities:

Follow everyone. There is only one passage leading to the "Entrance Hall". There are two snake-shaped teams in the arrival hall, one is American citizens and the other is foreign tourists. If you don't understand English, you can ask the people in line in China. Many people arrive in China by the same plane. See the immigration officer and hand over your passport, US customs declaration form and your relevant documents (round-trip air ticket). The official will take your picture (with a camera) and leave your fingerprints. Sometimes I ask a few questions, sometimes I don't ask (I don't know English, so I wrote a letter to the official before I left, explaining that I don't know English, the purpose of my coming to the United States, my place of residence in the United States, how long I plan to stay in the United States, and I have a round-trip ticket. If you have any questions, please call my children. The official stamped your passport with an "entry stamp". Get your passport, customs declaration form and related documents back.

Cameras, video recorders and mobile phones are not allowed in the arrival hall.

Second, through the customs:

After completing the immigration formalities, there is only one door and the baggage carousel comes out. Pick up the luggage. Take all the luggage through the customs, including the original checked baggage and the personal belongings on the plane. Go to see the customs officer. He accepts your customs declaration, and then you can go wherever he wants you to go. One is the inspection-free passage, the other is the machine airport, put your luggage on the conveyor belt designated by him, and the third is unpacking inspection. Generally, it is a machine inspection. Nobody looked for you after the machine, and you left.

After the customs inspection, it is still the same road, which is the baggage transfer office of airlines. If you have a connecting flight, please give your checked baggage to the corresponding airline. If you arrive at the airport at the end of your trip to Chicago, you can push the luggage cart and continue walking. This is the "Welcome Living Room for International Flights at Chicago Airport".

All the international flights of Chicago Airport are in Terminal T 5. If you change planes, United Airlines (UA) will be at T 1, T2; ; American Airlines (AA) are all in Terminal 3. There is an airport light rail between T 5 and other terminals.
