Buono a sapersi...  For further informations please consult the relevant page on the Italian Foreign Affairs Ministry website at the following address (in Italian only):


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; it has to be mentioned here, however, 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. 



  • By having an Italian parent(s);
  • By being born in Italy: including cases in which the parents are unknown, stateless or do not transmit their own citizenship to their child according to the legislation of the State to which they belong, as well as children found abandoned in Italy and for whom it is impossible to determine status civitatis (citizenship); 
  • Through paternal or maternal recognition while the child is a minor (in cases in which the child recognised is no longer a minor, he/she is obliged to elect to become a citizen within one year of recognition);
  • 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).

If the foreigner is of Italian descent (up to the 2nd degree) he/she can obtain citizenship in any of the following cases (alternatively): 


    • by serving in the Italian armed forces;

    • by residing legally in Italy for at least two years after reaching legal age.
    • If the foreigner was born in Italian territory he/she can obtain citizenship by residing legally and uninterruptedly in Italy from birth up to legal age.
