How to get to Los Angeles airport and enter the United States? What are the rules?

I just returned to the United States from China in July. When I arrived at the airport, I found that I was in trouble when I entered the country.

1. Let nature take its course after you get off the plane and you won't lose it.

Step 2 line up. In front of the entry window, write who this window is for, such as citizens, residents, visitors, etc. Please line up according to your situation. Ask the staff if you don't understand, and they will show you where the queue is suitable.

3. The length of the queue is very short. If it is short, 10 minutes is enough. If it is long, it will take an hour.

When it's your turn, the staff will ask you to show your passport, green card or visa, I-20, I94 (filled in on the plane) and ask questions (there is an interpreter at the airport. If you really don't understand, you can find an interpreter, but I don't recommend it. First, the attitude of the translator is not very good. Secondly, if you are a student, your ignorance of English will arouse his suspicion, and you may be refused entry. And ask you to take a photo without a hat and glasses. Citizens and residents should press the fingerprints of two thumbs. If you are not a citizen or resident, you should take the fingerprints of ten fingers, and there is an icon in front of the window. In the meantime, he may talk to you and just answer a few words casually. )

5. Then the baggage claim. There is a broadcast on the plane saying where you should claim your luggage. If you can't hear clearly, ask someone, at least the stewardess of your flight knows.

6. Before you leave the airport, there is another pass, that is, check whether there is anything in your luggage that is not allowed to be brought into the United States. If you are an American citizen, only accept the card (fill it out on the plane); If it is a green card, accept the card and ask one or two simple questions; If it weren't for these two, he might have more questions. If your English is not good enough to answer his questions, he will let you scan your luggage. If you find anything suspicious, you will be asked to open the box. If you find something that should not appear, you will be confiscated and fined. There are two people who receive the card and an Asian. According to my inference, it is possible to know Chinese. If English is not good, you can ask him. )

If it is baggage regulations, meat products, immature seeds, fruits, Ejiao products, etc. Not allowed to enter the United States; Besides, as long as you can board the plane smoothly in China, it is nothing.

By the way, there are other problems on that card (I never knew what it was called = =), such as what is the total value of your luggage, just don't write too much 300 or 400 (if you write it on the back, you will be taxed, but don't exceed that amount); What is the purpose of your coming to the United States, traveling, studying, or being a green card citizen; When you were in America, you said the address of your residence and so on.
