About connecting flights in the United States, the stay time is very short and urgent! ! ! ! !

Look at some answers. First of all, don't worry about what forms will be sent out on the plane. Just ask the flight attendant, not the I-20 form, but the I-94 form and a baggage declaration form.

In addition, in NYC, get off the plane, follow the crowd, go through the entry formalities, then pick up the luggage, then go out of the customs hall, then find the airline counter, check the luggage directly and give it to them for safekeeping. You don't have to do anything. But my general practice is to find the counter, show them the time of my next flight and ask them if they can catch it and why, because the flight time may be adjusted. If I can't arrive on time, please ask them to sign the next flight for me. After you check your luggage, there is usually a temporary security checkpoint. After that, go directly to the boarding gate. New york usually takes more than two hours. If time is too late, be sure to ask the staff at the counter to sign the next flight for you free of charge. If the same airline doesn't have the next flight, pretend to be pathetic. Just say that someone has driven for more than three hours and four hours to pick you up at the airport, so you must get there and let them do something, because ordinary airlines have some simple agreements with other airlines that they will give you tickets from other airlines, but in this case, you have to push your luggage to check in.
