Singapore to Shanghai to Singapore to Vietnam visa free in China?
Hello -
I have a US passport. I am flying US > Singapore > Shanghai less than 72 hours > Singapore > Vietnam. These are all one way tickets (it was easier and cheaper to book this way). I might be flying China Eastern into Shanghai and Singapore airlines out. I will be staying with a family member in Shanghai. I was also born in HK but left as a 2 yr old and I hold a US passport now - not sure if that matters but I know China has strict policies when it comes to that.
Can I use the 72/144 hour visa free transit option while in Shanghai? Can you confirm I just need to tell the airline at check-in at Singapore that I will only be staying for less than 3 days and then go to the visa free transit counter when I land in Shanghai? Am I missing anything?
Thank you for your help.
