Dual citizenship 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. The U.S. government recognizes the existence of dual citizenship and its citizens may possess dual citizenships. A naturalized U.S. citizen has the right to return to his/her native country and remain a U.S. citizen at the same time. Persons may have dual citizenship by automatic operation of different laws. For example, a child born in a foreign country to U.S. citizens may be, both a U.S. citizen and a citizen of the country of birth.
