Thanks for the welcome
I am still a bit confused about this whole passport thing
So you say to use my HKSAR passport to enter china. But what about when I leave US in the US side to go to china? Do i have to show my passport when leaving US? I should show my US passport when I leave US?
And you say to return to the US with my US passport. When I enter US with my US passport, would it be a problem at the US custom since there is no record on my US passport where I was coming from (since I am using my HKSAR passport not my US passport when I am leaving china)? Or they don't really care all they need to see is you have a US passport?
