Hi Everyone,
I have a couple of questions.

I am looking to fly from SFO-YVR-PVG. I have a 2 hour connection in YVR.
I am a US citizen.

I don't think I need any type of visa/transit visa for YVR (I have a visa for China). Is this correct?

What is the process in YVR? Customs, just security, neither? 2 hours enough?

I assume my luggage will be checked thru and I don't need to deal with it in YVR.

Thanks!
