High Quality Content by WIKIPEDIA articles! Italian nationality law is the law of Italy governing the acquisition, transmission and loss of Italian citizenship. Like many continental European countries it is largely based on jus sanguinis. It also incorporates many elements that are seen as favourable to the Italian diaspora. The Italian Parliament`s most recent major update of Italian nationality law is Law no. 91 of 1992, which came into force on August 15, 1992. Presidential decrees and ministerial directives, including several issued by the Ministry of the Interior, instruct the civil service how to apply Italy`s citizenship-related laws.
