According to Italy's current rules, only those with an Italian parent or grandparent can apply for ancestry-based, or ius sanguinis, Italian citizenship.
For individuals born outside of Italy, the law is even more restrictive, requiring that at least one parent or grandparent holds only Italian citizenship.
Under Italy’s current rules, only people with an Italian parent or grandparent are eligible to apply for ancestry-based or ius sanguinis Italian citizenship.
The new rules imply that those without a direct Italian ancestor may no longer be eligible, with specific conditions applying to those born abroad.
