Our daughter just got her US passport (she's been considered a Chinese citizen since birth, since she was born in China), and now we have to decide how to proceed. I know that legally she can't keep both because the Chinese don't allow this. However, she lives in China and she goes to school in China, so giving it up would be a headache. I know that many people keep both passports secretly, but I've been searching on how to do this. I know that it involves a trip to a third country when traveling between the US and China, but I don't understand the logistics. For example, if I cross the border by land from Shenzhen to Hong Kong, how does this work? Does she need permission to travel to Hong Kong in her Chinese passport? Will it look strange because her US passport has absolutely nothing in it? Another question... If we book flights to the US from the mainland, do we actually have to go through customs in the middle country to make this work? For example, can we fly from Beijing to Tokyo and then to the US without going through Japanese customs or do we have to go through customs to make this work. If anyone has any experience with this, I would appreciate the help. I've tried searching the forum, but I can't find specifics. Thanks, Socks
