If you are an EU citizen staying in Italy for more than three months, you have to register to the Anagrafe cittadini temporaneamente presenti (Registry Office for Temporarily Present Citizens) at the Municipality Office. They will require specific documents to be submitted. We recommend you to contact them in advance in order to have a complete list of all the necessary documents.
If you are a non-EU citizen, you are allowed to stay in Italy for less than 3 months and in this case you do not need to apply for a Residence Permit. However, please note that:
How to apply:
