《美国政府允许或承认双重国籍》

无论是美国国务院,还是美国移民局，都明白无误的指出，美国政府“允许或承认双重国籍”。

下面一段话来自美国移民局官方网站：

https://www.usimmigrationsupport.org/dual-citizenship.html

Dual Citizenship: The U.S. government allows dual citizenship. United States law recognizes U.S. Dual Citizenship, but the U.S. government does not encourage it is as a matter of policy due to the problems that may arise from it. It is important to understand that a foreign citizen does NOT lose his or her citizenship when becoming a U.S. citizen. An individual that becomes a U.S. citizen through naturalization may keep his or her original citizenship. However, as some countries do not recognize dual citizenship, it is important to consider it carefully before applying for U.S. citizenship.

笔者来翻译一下：

双重国籍：美国政府允许双重国籍。虽然美国法律承认美国（US）双重国籍，但是由于由此引起的一些问题，美国政府在政策上不鼓励双重国籍。这一点非常重要：当一个外国公民成为美国国籍时，他或她不会时失去其国籍。通过归化过程成为美国公民的任何个人，可以保留他或她都原有的国籍。然而，由于一些国家不承认双重国籍，在申请美国国籍是，要仔细考虑到这一点。

望高手指正。
