How many years of residence do you need to apply for Italian citizenship?
For naturalisation, as a rule you need 10 years of legal residence as a non-EU national, 4 years as a citizen of another EU country, 5 years for refugees and stateless persons, 2 years if you have an Italian-born parent or grandparent, and 3 years if you were born in Italy. Through marriage to an Italian citizen, while residing in Italy, the period is 2 years, reduced to 1 year if there are children.
