I want to go to America. What are the steps of airport, plane, customs and luggage on the way from Beijing Airport to Los Angeles? What information should I fill in?

1. Check in at the airline check-in counter and check your luggage. At this time, hand over your passport, air ticket and luggage, and get back your passport, air ticket, boarding pass and luggage ticket. Pay attention to ask whether the luggage is checked to the final destination or taken out at the stop.

2. Go through customs, frontier defense and quarantine. It is called the Customs Entry-Exit Inspection and Quarantine (ICQ) abroad. Ask the staff where they went through the customs, find the customs declaration form and fill it out. If you have valuables such as SLR cameras and gold watches that need to be brought back to China, just fill them in, and don't fill in the rest. Submit passport, boarding pass and declaration form through customs. The declaration form will be returned to you after being stamped, and you can use it when you come back.

Line up directly in front of the border defense (you used to fill out the exit card, but now it's not needed) and submit your passport, air ticket and boarding pass. Passport stamp.

If it's okay, you can go through quarantine directly without stopping.

3. Pass the security check. As long as you have been on an airplane, you will experience this situation.

4. Wait at the boarding gate. Some flights need to take the Grand Barra at the boarding gate.

Before getting off the plane, the stewardess will usually give you the customs declaration form and border entry card of the country of entry in advance, and some will also have the quarantine declaration form to fill in on the plane. When you enter the country, you have to go through the border inspection before you pick up your luggage. You may need a baggage tag when you pick up your baggage, and then you will go through the customs.
