To apply for Italian citizenship, the following is required:

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.

Necessary Documents:

• Valid identity document;
• Extract of Birth Certificate, original, completed with all details, translated and legalised (valid within 90 days of the date of issue);

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.
