Does the United States recognize multiple nationalities?

Can I have dual citizenship as a U.S. citizen? A vague policy where the answer is yes or no. Maintain dual or multiple nationality between the United States and other countries. As a U.S. citizen, you have the nationality of the place of birth. Those who are naturalized in the United States maintain their original nationality, and those who are U.S. citizens later join other nationalities. To maintain a nationality other than the United States, sometimes the person does not need to swear an oath to renounce U.S. citizenship before a U.S. consulate. U.S. law itself is ambiguous regarding dual or multiple nationalities. \x0d\More than a decade ago, the U.S. State Department made a fuss over dual-citizens who had acquired foreign nationality. It absolutely insisted on not recognizing dual nationality. In recent years, it has relaxed a lot, and you can maintain your dual-citizen status without confronting the State Department. \x0d\What is more unclear is that people who have obtained U.S. citizenship through naturalization applications still want to maintain their original nationality. Legally speaking, a person who is naturalized in the United States has renounced other nationalities when taking the naturalization oath, but if he maintains his original nationality, there is a legal contradiction in that he can lose his American citizenship. In fact, the U.S. State Department adopts an out-of-sight, out-of-mind approach to this type of dual citizenship and mostly ignores it. Because many countries do not recognize U.S. naturalization, taking the oath of naturalization in the United States will not affect the original nationality and will still be treated as citizens. Therefore, the U.S. State Department is not willing to get angry with the country of origin for dual nationals. \x0d\In the same situation, if a U.S. citizen "swears" to renounce U.S. citizenship when naturalized in a foreign country, as long as the U.S. citizen is not required to go to the U.S. consulate to publicly declare renunciation of U.S. citizenship, the U.S. State Department will just muddle along and ignore it. Taking an oath to renounce your American citizenship at the U.S. Consulate is a serious act. Of course, you cannot keep your U.S. citizenship. \x0d\Does the United States "recognize" dual citizenship? The answer depends on how "recognition" is interpreted. If it is illegal to hold U.S. and other nationalities, the answer is wrong because the United States recognizes dual nationality. If it is said that foreign nationality is irrelevant and foreign nationality is not recognized, the answer is right. \x0d\The main purpose of U.S. citizenship laws is to determine an individual's U.S. citizenship, rather than focusing on whether the person has other nationalities. If the party concerned is a U.S. citizen and lives in the United States, he is completely bound by U.S. law. Whether the party has foreign nationality has no effect in U.S. law and is not recognized. \x0d\Dual national residents with U.S. nationality will not be treated differently in the United States simply because they have other nationalities. If they violate U.S. laws, do not expect that the United States will recognize the ability of consular intervention of other countries. Similarly, dual nationals with U.S. citizenship, like other U.S. citizens, must present U.S. travel documents, such as passports, when returning to the United States. \x0d\There have been cases where dual nationals had problems when entering customs, and they expressed their identity with a nationality other than the United States. In the past, using identity documents from other countries was grounds for revoking U.S. citizenship. Although it is not so serious now, it is better to use If you return to the United States with a U.S. passport and use a passport from another country, you will not get better protection, but will cause other troubles. \x0d\The task of the U.S. immigration officers stationed at the port of entry is to decide whether the visitor can enter the United States, which country he is from, and which kind of passport he should take. This is only used to prove that the person concerned has dual nationality of the United States and a foreign country, and one of them is a U.S. citizen. , so that the person concerned can "legally enter", reside and stay indefinitely. Therefore, whether a US citizen has the nationality of other countries is not an issue that port of entry officials focus on at all, so there is no need to produce evidence of citizens of other countries. \x0d\ Therefore, whether the United States recognizes dual nationality, the answer should be that within the United States, other nationalities of American citizens are really irrelevant. Should they recognize it or not?
