To apply for Italian citizenship, the following is required:
Legal residency in Italy:
10 years for non-EU citizens;
5 years after adoption for an adult foreigner adopted by an Italian citizen, for stateless persons, for political refugees, and for adult children of an Italian citizen;

3 years for the descendants of Italian citizens jure sanguinis (up to the second degree – grandparents) and for those born in Italy.
Proof of income: personal or family income (CUD, UNICO or 730) from the 3 years preceding the application for Italian citizenship. The minimum amount for each year in 2015 is: €8,263.31 (if the applicant has no dependents); €11,362.05 (if the applicant has a dependent spouse – this value is increased by €516.00 for each additional dependent person).
The application is evaluated by the Ministry of the Interior on a case by case basis.
The applicant must have no significant criminal records.
Valid identity document;
Extract of Birth Certificate, original, completed with all details, translated and legalised (valid within 90 days of the date of issue);
Certificate of Family Status;

All applications for citizenship by residency are sent to the Italian Ministry of the Interior in Rome and the process takes an average of 2 years.
Citizenship by residency is a concession and not a right, so the Italian State may deny it if the aforementioned requirements are not met.
After receiving notification of the grant of citizenship, the applicant has 6 months to take the oath.
