加拿大护照上的中国签证还有六年有效期,刚变美国公民,绿卡被收。可以用加拿大护照上的中国签证回中国,用美国护照回美吗?
-I think it is fine. But if you use the Canada pasport to enter China, then you also need to use it ot leave China. Then, you can use the US passort to enter US. Another choice is show both passports to enter China, and ask the Chinese Customs office to record you as a US citizen to enter China.
也就是说要不要再申请中国签证?
-No.
