谷爱凌双重国籍问题——按照美国法律解释

争论点无非就是谷爱凌加入了中国国籍但是没有放弃美国国籍巴拉巴拉

以及2019年口头声明无效巴拉巴拉

引用美国法律：

Section 349 of the INA (8 U.S.C. 1481), as amended, states that U.S. nationals are subject to loss of nationality if they perform certain specifiedacts voluntarily and with the intention to relinquish U.S. nationality. Briefly stated, these acts include:

obtaining naturalization in a foreign state after the age of 18 (Sec. 349 (a) (1) INA);
taking an oath, affirmation or other formal declaration of allegiance to a foreign state or its political subdivisions after the age of 18 (Sec. 349 (a) (2) INA);
entering or serving in the armed forces of a foreign state engaged in hostilities against the United States or serving as a commissioned or non-commissioned officer in the armed forces of a foreign state (Sec. 349 (a) (3) INA);
accepting employment with a foreign government after the age of 18 if (a) one has the nationality of that foreign state or (b) an oath or declaration of allegiance is required in accepting the position (Sec. 349 (a) (4) INA);
formally renouncing U.S. nationality before a U.S. diplomatic or consular officer outside the United States (sec. 349 (a) (5) INA);
formally renouncing U.S. nationality within the United States (The Department of Homeland Security is responsible for implementing this section of the law, and any inquiries should be directed to DHS) (Sec. 349 (a) (6) INA);
conviction for an act of treason against the Government of the United States or for attempting by force to overthrow, or bear arms against, the Government of the United States (Sec. 349 (a) (7) INA).
Administrative Presumption of Intent to Retain U.S. Citizenship

As already noted, the actions listed above will result in the loss of U.S. nationality if performed voluntarily and with the intention of relinquishing U.S. nationality. The Department has adopted an administrative presumption that U.S. nationals intend to retain United States nationality when they: obtain naturalization in a foreign state (INA 349 (a)(1)); declare their allegiance to a foreign state (INA 349(a)(2)); serve as an officer in the armed forces of a foreign state not engaged in hostilities with the United States (INA 349(a)(3)); or accept non-policy level employment with a foreign government (INA 349(a)(4)). In accordance with the administrative presumption, when an individual commits one of the foregoing acts, that person will retain U.S. nationality unless he or she affirmatively, explicitly, and unequivocally asserts an intention to relinquish such nationality.

简单翻一下：
美国公民放弃美国国籍的7种方式
1.18岁后加入他国国籍
2.宣誓效忠他国
3.加入他国武装
4.具备外国职务(如果接受的前提是加入他国国籍或者宣誓效忠他国)
5.在美国境外领事馆申请放弃
6.在美国国内申请放弃
7.叛国

特别约定：其中567自动生效。1234行为不会自动触发生效，需要明确表明自己放弃美国国籍的意愿。

现在已知事实。
1.谷爱凌加入了中国国籍(加了一个不承认双国籍的国家)
2.谷爱凌在2019年(此时未成年)宣布过放弃美国国籍。

如果真正的美国人和精神美国人非要强调这是双国籍。
那么必须保证2点
1.谷爱凌在成年之后没有声明过放弃美国国籍的意愿(intention)
2.加入一个不承认双国籍的国家的行为不包含放弃没国籍的意愿。

不然谷爱凌就是一个单国籍的中国人。

至于提到的各种申请balabala，也只是条文中的5和6而已。不是所有的退出美国国籍的方法。
