The law governing citizenship in Italy is mainly based on the ius sanguinis principle. Citizenship in Italy is regulated by Law no. 91 of 1992 and can be granted by birth, marriage and naturalisation. Italian citizenship is acquired at birth either if born to an Italian citizen or if one is born to unknown or stateless parents. In respect to the acquisition of citizenship by naturalisation, this is not easily obtained since this is granted at the discretion of the public administration after showing evidence of ten years of legal residence in the country.
Following the enactment of the law in 1992, Italian citizens that acquire a second citizenship do not lose their Italian citizenship unless a formal request for renunciation is made. As of 2010 the Italian government also adheres to the Strasbourg Convention and therefore allows for dual citizenship of Italian citizens. The Italian law does not specify any consequences in relation to the registration or renunciation of original citizenship. Italian nationals can hold dual citizenship without any special conditions.
