Dual Nationality Section 101(a)(22) of the Immigration and Nationality Act (INA) states that “the term ‘national of the United States’ means (A) a citizen of the United States, or (B) a person who, though not a citizen of the United States, owes permanent allegiance to the United States.” Therefore, U.S. citizens are also U.S. nationals. Non-citizen nationality status refers only individuals who were born either in American Samoa or on Swains Island to parents who are not citizens of the United States. The concept of dual nationality means that a person is a national of two countries at the same time. Each country has its own nationality laws based on its own policy. Persons may have dual nationality by automatic operation of different laws rather than by choice. For example, a child born in a foreign country to U.S. national parents may be both a U.S. national and a national of the country of birth. Or, an individual having one nationality at birth may naturalize at a later date in another country and become a dual national. U.S. law does not mention dual nationality or require a person to choose one nationality or another. A U.S. citizen may naturalize in a foreign state without any risk to his or her U.S. citizenship. However, persons who acquire a foreign nationality after age 18 by applying for it may relinquish their U.S. nationality if they wish to do so. In order to relinquish U.S. nationality by virtue of naturalization as a citizen of a foreign state, the law requires that the person must apply for the foreign nationality voluntarily and with the intention to relinquish U.S. nationality. Intent may be shown by the person’s statements and conduct. Dual nationals owe allegiance to both the United States and the foreign country. They are required to obey the laws of both countries, and either country has the right to enforce its laws. It is important to note the problems attendant to dual nationality. Claims of other countries upon U.S. dual-nationals often place them in situations where their obligations to one country are in conflict with the laws of the other. In addition, their dual nationality may hamper efforts of the U.S. Government to provide consular protection to them when they are abroad, especially when they are in the country of their second nationality. U.S. nationals, including dual nationals, must use a U.S. passport to enter and leave the United States. Dual nationals may also be required by the foreign country to use its passport to enter and leave that country. Use of the foreign passport to travel to or from a country other than the United States is not inconsistent with U.S. law. You can find additional inform

Dual citizenship had previously been banned in the United States, but in 1967 the US Supreme Court struck down most laws forbidding dual citizenship. However, the US government remained disdainful of dual citizenship for some time. To this day, candidates for US citizenship through naturalization are forced to (at least hypothetically) renounce their previous citizenship at the United States naturalization ceremony. The renouncing of one’s previous citizenship is part of the oath that new US citizens must take, and failing to honor that oath could result in the loss of citizenship in the United States. Some cases that have been brought before the Department of State in the past involve people who became naturalized US citizens but maintained a residency and life in their country of previous citizenship. While most countries recognize the Oath of Allegiance in the United States to be a binding contract regarding one’s citizenship, other countries have stated that the oath has no effect on their own citizenship laws. The US government used to aggressively pursue these cases to get the dual citizens to renounce their citizenship, but this is no longer the case. Additionally, young children who naturalize in the United States along with their parents didn’t take the Oath of Allegiance — even though their parents did — and can technically still hold on to their previous citizenship. People who have held dual citizenship since birth or childhood — or who became citizens of another country after becoming a US citizen and were not asked to renounce their previous citizenship — can remain dual citizens in the United States.
搜了一下 貌似可以
没说不可以，只是不承认
是通过父母自然取得的还是归化的？ 只要他没有声明放弃美国国籍，入境美国用美国护照，有其他国籍对其美籍没影响。
本来就一直跪着呢，天天黑命贵不离口的垃圾而已
你自己去国务院官网去看看吧，这块很模糊，不是你说的那么简单
没有这一说，就是无视，只要你有美国国籍，美国政府就永远把你当成美国人处理，其他国家国籍归其他国家管理
扯吧。。
你翻墙来的？
不仅仅是恨TG了，林书豪加入台湾籍都要骂。
我听我同事说，遇到撤侨的时候，美国优先撤只有美国国籍的，再考虑双国籍的。她本来可以加一个欧洲某国籍但因为听说这个就没加
双国籍还是只有美籍住在海外都可以投票的
欧洲这里美国人出没多的地方 大选的时候也有拉票团队的
我第一次走在大街上听见他们喊口号的时候 以为自己美国新闻看多了幻听了。。。
话说2016年密西根大选夜没叫就是差距太小了 海外票还没拆呢 一般海外票总数根本没有理论上改变结果的可能
他又不是归化公民，没这个条件。他爱加入谁都行，美国承认这个双重国籍的。
你朋友想得真远……
这是胡说
比如你在其他国家有了麻烦，只要你有美国护照，美国领事馆就会当你是美国籍捞你，不管你有没有第二国籍。
现在多了一条，只要你是美国籍，就全球征税～～
我觉得咱们要首先定义一下什么叫承认。如果你说的承认是不取消他的美国国籍，那么确实是承认；如果你说的承认是美国政府把他当作台湾人看，那么对不起，不承认，只要他还有美籍，那么美国政府永远只把他看成美国人
承认和不否认两码事，比如美国，你拿其他国家护照入境第三国，在那个第三国美国就不提供领事保护，你拿外国护照入境美国，你的美籍就可能出问题。真正完全承认多重国籍的国家，就没有这个问题。
例1、美國籍的人想擁有台灣籍必須先放棄美國籍。 例2、原中國大陸籍的要入台籍需注銷大陸戶籍，擁有了台籍之後，可以再申請其他國籍。
对啊，他加入的话兵役怎么办？
他拿中华民国护照就是为了来往方便，去大陆可以办台胞证，不用办签证。
两个国家。西朝鲜和北朝鲜
台湾籍就可以不算CBA外援了吧？
这边湾区家长的孩子要是能象林书豪，做梦都要笑醒。
这个想一下都知道是假的
他好像走的是杰出人才，免兵役
他申請的啦,最好是台灣主動給他,胡說八道
好像是这样的，听我台湾朋友说他们移民美国不需要放弃台湾籍，都是双重国籍

不过林书豪应该是属于父母来自台湾，所以自动获得的那种，而不是跟台湾没有关系，成年后主动申请的。。。
国内篮协早把这条路堵死了。港澳台球员必须没有其他国籍才算内援。林除非放弃美国国籍，否则不可能算内援的。另外从挣💰的角度看，林也不可能放弃的。上个赛季，林的薪水是2千万。如果加入大陆，最多只能拿9百万，按港澳台算更惨，前两年最多50万一年。
据说林申请台湾文件主要是为了出入境方便，疫情期间，美国护照现在无论去大陆和台湾都不受欢迎，湾湾护照方便多了。
当然算，没有其他国藉的才可以算内援
CBA规定的很清楚，没有其他国籍的才行。
我去问问CBA的朋友，确实哦，以前有台胞证的没有其他国籍，林书豪是第一例。不过也可能有其他考虑吧，感觉他父母也很希望他这么做，还会去特意感谢台湾的内务部长。
他大慨是拿護照簽僑居，雖然有國籍但沒有入戶籍，住海外的常常都用這種方式
