Multiple citizenship

Multiple citizenship, dual citizenship, multiple nationality or dual nationality, is a person's citizenship status, in which a person is concurrently regarded as a citizen of more than one state under the laws of those states. There is no international convention which determines the nationality or citizen status of a person. Citizenship status is defined exclusively by national laws, which can vary and can conflict. Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship. Colloquial speech refers to people ``holding'' multiple citizenship, but technically each nation makes a claim that a particular person is considered its national.
