we are planning a visit to the USA for the first time in late November with our daughter who now holds USA and Chinese passports. we want to keep her Chinese citizenship for now, so we applied for a visa to the USA for her Chinese passport and received it already. however, we are unclear what the procedure is once we arrive in USA, where she is supposed to use her USA passport to enter the country. and how this will affect her status upon return to China -- ie, she will not have a stamp on her Chinese passport, so how to explain that to Chinese immigration? anyone have any experience with this? very much appreciate your help!!
