Please go to America and transfer in Detroit! If the connecting flight is only 1.5 hours, will it be too late to catch the next flight? If you can't catch up with the connecting ticket, it will all be invalid? 1) On the plane to Detroit International Airport, fill out the I-94 form and customs declaration form (which will be issued to passengers by the flight attendant). Although there are Chinese forms, these two forms must be filled in English. It is necessary to bring a pen because you have to fill out the form.

2) Arrive at Detroit International Airport (airport code: DTW). All inbound international flights stop at Hall A.. After getting off the plane, follow the crowd. There is only one way to get to the "Arrival Hall" (floor 4 of Concourse A ***4 *, which is on the ll floor, that is, the lowest floor) and queue up [there are two different teams: one is an American citizen and a green card holder, and the other is a non-immigrant visitor]. If you don't know which line to line up, ask the people from China who arrived on the same plane. There are many people in China.

See the officials of the Department of Homeland Security, hand in I-94, show your passport and customs declaration form, and other materials (DS-20 19 is required if you have a J- 1 visa), and press your fingerprints. Officials of the US Department of Homeland Security may ask a few questions, and sometimes ask nothing.

With the official approval, the half chapter of I-94 should be affixed to your passport (this half chapter of I-94 is very important, so don't lose it when you leave the United States). Get your passport, documents and customs declaration back.

This procedure, with many people waiting in line, takes a long time and few people, about half an hour or so.

3) Enter the "baggage claim area for international flights" by arriving at the lobby. There is only one door. Come out. Pick up your baggage on the baggage carousel of your flight.

4) After the customs inspection, they submit the customs report and conduct spot checks.

There are three situations: one possibility is that the customs officer receives your customs declaration form, then waves his hand, you go, and you leave by the next passage; On the other hand, they accept your customs declaration form and ask you to put your luggage (all luggage, including checked luggage and carry-on luggage) on the conveyor belt of the inspection machine. After the luggage comes, no one is looking for you, so just put it on the trolley and go. There is a third possibility. After the machine inspection, some customs officers ask for unpacking inspection. You have to take all your luggage to the customs inspection counter and open it on the spot for them to check. As long as it is not the third case, generally speaking, 10 for several minutes. If it is unpacking inspection, it is difficult to estimate the time. Generally speaking, most of them are the second case.

5) If you bought it from China (Shanghai Pudong Airport? ) to Portland, USA, then you should hand in your luggage directly (be careful not to damage or lose the airline baggage tag on your luggage and the baggage tag posted on your ticket, which has the names of your luggage departure airport and destination airport). Find your airline (DL? ) conveyor belt [just at the exit of the customs inspection office, with obvious signs and their airline staff next to it], put it on.

Then it passes through the security door, and a security guard passes through it with a metal detector. After the security door, it is the escalator. After going up, turn right and you will see a tunnel.

If you buy a ticket from an American Airlines airport in China (Shanghai, Beijing) to Portland, generally speaking, when boarding at China Airport, the check-in counter will put an airport in China (Shanghai Pudong Airport, airport code PVG；; ; Beijing Capital Airport (airport code PEK) to Detroit (airport code DTW) will be given to you together with the boarding pass for connecting flight in Detroit. The boarding pass has the flight number from Detroit to Portland Airport you want to go to, and the boarding gate number of your boarding at Detroit DTW International Airport. If you don't have the boarding gate number (the flight number is definitely available), just check the flight indication TV screen of the airport at Detroit Airport and compare your flight number, you can see the boarding gate corresponding to the Detroit-Portland flight.

After the escalator, there is a big tunnel on the right hand side, a long big tunnel, leading to B and C (if your boarding gate is B B×××× or C C×××, just go this way and cross a colorful lantern tunnel, and you will reach the junction of B and C). If you go to A (if your boarding gate is A ××, take this road), it seems that the escalator turns left, which is a short tunnel.

Plaza A is very big and has an indoor light rail. If the gate is far away, you can take the small train at home. If you don't want to take the light rail, you can walk there.

Detroit airport will often broadcast a sentence in Chinese, "Please check the time. What time is it in Detroit? " Only this sentence (because different parts of the United States implement different time zones). The signs of the airport (icons and English) are very clear and numerous.

Transfer time 1.5 hours, a little nervous.

1. When changing your boarding pass at an airport in China (I don't know the boarding airport of your ticket, so I use "An Airport"), please give you a seat in the front row at the check-in counter (Americans get off the plane in an orderly way, so if you want to get off the plane early, you should have a seat in the front row).

2. As soon as you get out of the engine room and in the corridor, walk faster and step into the "entry hall" as early as possible.

In case you miss the flight from Detroit to Portland, you can find your airline and change it. This visa change is free of charge.
