Visa free travel to Shanghai
Hello - I am an American passport holder currently in China on a 90 day, double entry tourist visa. My entry into China counted as one entry and my trip to and from Hong Kong counted as another. I want to travel to Thailand and back to China to catch my return trip back to the US 1 day later.
I have an electronic ticket. Can I show my print out from the airline at PVG immigration?
Also, I won't have a valid visa when I check-in at BKK. Usually they check to make sure I have a proper visa. What happens in BKK?
