Urgent! ! ! This is my first time to America. This is an immigrant visa. How long does it take to transfer from San Francisco?

It's China International Airlines, isn't it? There is enough time. The connecting flight is simple. Only 1000 meters on the way. Two or three hours is the time for you to fill out the form, which is easier said than done. When entering the country, officials will only ask a few simple questions, and then they will be released. Actually, an hour at most is enough. Don't worry.

And when you get off the plane, someone who knows Chinese will guide you, which is quite humanized.
