Starting from January 1st, British citizens and their family members residing in Italy must apply for a residence permit in electronic format at the Police headquarters (Questura) having jurisdiction over their place of residency in Italy.
The new document will indicate that it is issued on the basis of the Withdrawal Agreement and will allow the holder to exercise the rights recognized by the Agreement. The document will be valid for 5 years (or 10 years if the applicant has acquired the right of permanent residence after 5 years of legal and continuous stay). To apply for the document, it is necessary to book an appointment with the relevant police office and submit the “Attestazione di iscrizione Anagrafica” previously obtained from the City Council of residency.
