Where do I clear Customs? NRT>SFO>YVR
 

Does anyone know if I am required to clear US Customs on this trip from Narita to Vancouver via San Francisco?

NRT > SFO - UA838
SFO > YVR UA1116


Thanks!

Everyone that enters the USA is required to clear customs at the point of entry (SFO in your case) even if they are flying somewhere else. Going to Canada you may be required to clear customs again. I have not been to Canada since all the changes with passport requirements.

With the exception of Air NZ passengers, travelling LHR-LAX-AKL or AKL-LAX-LHR.

There is always an exception. Thanks for the information. That is why I love this webiste. There is always something new to learn.

You will need to clear U.S. Customs at SFO, and then Canadian Customs at YVR. There will be no recognition in Canada of where you started your journey, the bottom line is that you arrived into Canada from the U.S.

One small note: On the Canada Customs form, you will need to check the "Other Country via U.S." box when answering where you came from.

Side note: It looks like you have about one hour and 45 minutes in connection time at SFO. Don't delay when leaving U.S. Customs and going to your connecting gate.
