Am I allowed to be a dual citizen of Australia and the United States
I recently received a question from an individual living in Daly City as to whether she could be both a citizen of Australia and the United States if she became a U.S. citizen.
The answer is yes. Australia allows its citizens to become a citizen of another country, if the other country allows it. You can read more about the Australian law on the Australian government's website for their Department of Immigration and Citizenship.
U.S. law does not mention dual nationality or require a person to choose one nationality over another. Thus, U.S. law permits it as long as the other country permits it. Along with perhaps acquiring more rights as a dual national, you acquire more responsibility. As the State Department website on dual nationality further explains, dual nationals owe allegiance to both countries and must obey the laws of both countries. Either country has the right to enforce its laws, particularly if the person later travels there. You are therefore not exempt from observing a law, such as the payment of taxes, simply because you are a citizen of another country.
