Thanks for the fast reply. Yea, I'll remember to leave/enter the US with my US passport in the future.
I will leave/enter taiwan with my tw passport and leave/enter hk with my US passport.
Oh wait... wont the tw customs check my tw passport for a hk visa, as I recall this is the procedure. As I mentioned, I do not have enough time to get a hk visa on my tw passport.
thanks
edit, oh ok I reread your post, so if there are any problems at the tw customs, I just show them my US passport?
