Citizenship through Italian parents/ancestors (“iure sanguinis”)


Citizenship through Italian parents/ancestors (“iure sanguinis”)

The requirements applicable to every single case are determined by the law in force at the time of the descendant's birth.
The applicant shall submit documentation requested. Nevertheless, in case of doubt, the Office is allowed to ask for further information or documents.
