Multiple citizenship, also called dual citizenship or 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, which is defined exclusively by national laws, which vary and can be inconsistent with each other.
 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 this person be considered its national.
