Whether you lose Vietnamese citizenship after U.S. naturalization is a common question among many Vietnamese who have settled in the United States. Can Vietnamese nationals retain dual citizenship after becoming naturalized U.S. citizens? Letu2019s explore the details with ICAFAS below.
Do you lose Vietnamese citizenship after U.S. naturalization?
Under the Law on Vietnamese Nationality, Vietnamese citizens residing abroad may still retain their Vietnamese citizenship, except in cases where they voluntarily renounce it or are deprived of it. Under U.S. immigration and nationality law, a person may hold dual citizenship. The United States does not prohibit its citizens from acquiring another nationality and does not require them to choose only one citizenship.

Therefore, after obtaining U.S. citizenship, Vietnamese citizens do not lose their Vietnamese citizenship and may retain dual citizenship status, except in certain cases where citizenship is revoked in accordance with the law. This is an advantage for Vietnamese living in the United States compared to many other countries. For example, in Germany, the Netherlands, and Japan, individuals are generally required to renounce their original citizenship in order to acquire a new one.
