FAQs: Does the US Allow Dual Citizenship?

United States laws do not require a person to choose one nationality or another. Dual citizenship means that a person is a national of two countries at the same time. At one time dual citizenship was banned in the United States, but in 1967 the US Supreme Court struck down most laws against dual citizenship.

However, immigrants who are candidates for US citizenship through naturalization are required to renounce their previous citizenship and their allegiance to out nationalities in their oath of allegiance to the United States at their naturalization ceremony. Failing to honor their oath could result in the loss of their United States citizenship.

The Immigration and Nationality Act (INA) Section 101(a)(22) says about dual nationality 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.”

U.S. citizens, including dual nationals, must use a U.S. passport to enter and leave the United States.
