Italian citizenship is based on the principle of ius sanguinis (blood right) by which a child born of an Italian father or mother is Italian; nevertheless, it must be kept in mind that the mother citizen has only transmitted citizenship to minor children since January 1st 1948 as a result of a ruling by the Constitutional Court. Italian citizenship is currently regulated by Law No. 91 of 5 December 1992, which, unlike the previous law, re-evaluates the importance of individual desire in the gain or loss of citizenship and acknowledges the right to hold citizenship in more than one country, except in the case of the various provisions of international agreements.

which the child recognised is no longer a minor, he/she is obliged to elect to become a citizen within one year of recognition);4. by adoption, both if the foreign minor is adopted by an Italian citizen by means of

the Italian Judicial Authorities, as well as in the case in which adoption is granted abroad and made effective in Italy through a writ, issued by the Juvenile Court and registered with the Civil Registry.If the adoptee is no longer a minor he/she can become a naturalised Italian citizen after 5 years of legal residence in Italy (see How to Apply: Naturalisation).
