回复：美国承认双重国籍吗？

可否用美国护照出入美国，然后星家玻护照出入中国，避免签证问题？我记得星护照可以免签呆两周？

-If you have 星家玻 nationality first, and then you got the US citizenship, you can have dual nationalities at the same time (星家玻 and US) as long as 星家玻 allow you to keep your 星家玻 citizenship after you got the US citizenship.

See the following websites for some basic information:
