美國是否承認雙重國籍？

剛才有網友說美國是承認雙重國籍的，對此，我一直是心有疑問的，好像是好像又不是吧。
美國是否承認雙重國籍？很多人都認為是，美國公民可以擁有其他國籍。事實上我本人就認識幾個朋友除美國護照外還手持英國，中華民國（台灣），等護照。而且美國嘛有這麼多的盟友，互相免簽證的國家一大綹，承認一個雙重多重國籍又有什麼關係？
然而最近才從紐瓦克移民局主管移民的主任那裡得到正式答案：美國不承認雙重國籍。美國不在乎你是否有其他國家或地區的護照，也不在乎你是否用其他護照進入其他國家，但你在從境外回到美國時，如果你是美公民則必須使用美國護照，否則你可能被海關當場羈押，並被登記在案。
驚呀之餘嘗試理解為何美國不承認雙重國籍。其實美國也是把公民對國家的忠誠看得很重的。作為一個移民國家，很多公民都有複雜的歷史背景。美國既不強迫你放棄其它國家的國籍，但也不承認這些國籍。在美國政府看來，你僅僅是一個美國公民，是一個面對利益衝突必須選擇效忠於美國的人。要求公民在海外按自己的規矩做顯然不實際，但你回來時就不一樣啦。如果你進自己的國門還要裝作是外國人，那你也太不把自己的公民身份當回事，更遑論在戰爭期間你要對自己所選擇紮根的這個國家盡忠盡職了！

貌似有些複雜，出境的時候用什麼護照，回來還是要用什麼護照吧，不然沒有出入境記錄

千里之外: 貌似有些複雜，出境的時候用什麼護照，回來還是要用什麼護照吧，不然沒有出入境記錄

然也

我不認為你的理解是對的。看看美國國務院網站上是怎麼說的吧：

Dual Nationality

The concept of dual nationality means that a person is a citizen of two countries at the same time. Each country has its own citizenship 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. citizen parents may be both a U.S. citizen and a citizen of the country of birth.

A U.S. citizen may acquire foreign citizenship by marriage, or a person naturalized as a U.S. citizen may not lose the citizenship of the country of birth.U.S. law does not mention dual nationality or require a person to choose one citizenship or another. Also, a person who is automatically granted another citizenship does not risk losing U.S. citizenship. However, a person who acquires a foreign citizenship by applying for it may lose U.S. citizenship. In order to lose U.S. citizenship, the law requires that the person must apply for the foreign citizenship voluntarily, by free choice, and with the intention to give up U.S. citizenship.

Intent can be shown by the person's statements or conduct.The U.S. Government recognizes that dual nationality exists but does not encourage it as a matter of policy because of the problems it may cause. Claims of other countries on dual national U.S. citizens may conflict with U.S. law, and dual nationality may limit U.S. Government efforts to assist citizens abroad. The country where a dual national is located generally has a stronger claim to that person's allegiance.

However, dual nationals owe allegiance to both the United States and the foreign country. They are required to obey the laws of both countries. Either country has the right to enforce its laws, particularly if the person later travels there.Most U.S. citizens, 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 does not endanger U.S. citizenship.Most countries permit a person to renounce or otherwise lose citizenship.

Information on losing foreign citizenship can be obtained from the foreign country's embassy and consulates in the United States. Americans can renounce U.S. citizenship in the proper form at U.S. embassies and consulates abroad.

注意上面貼的美國國務院網站上的這句話：
The U.S. Government recognizes that dual nationality exists but does not encourage it as a matter of policy because of the problems it may cause.
這句話的意思：美國政府認可（或者很輕的口氣可以翻譯成「知道」）雙重國籍的存在，但並不鼓勵之，因為。。。。

可見，這裡沒有一點說明美國政府不承認雙重國籍的意思。不鼓勵和不承認，完全兩碼事。無論哪個移民官如何解釋，法律是條文，不是哪個個人的解釋可以覆蓋的。

多謝指教啊

是這麼回事哦！
