Once the Vigile confirms your residence, the comune may take a few days to include you in their database. Once your registration in the APR is complete, you can schedule a citizenship appointment or just walk in to present your application if walk-ins are accepted, and they usually are in all but the largest cities.
The Stato Civile officer will thoroughly examine all your documentation and, if everything is in good order and suitable according to the clerk’s standards and criteria, then you will be issued a document by the clerk stating that you have presented your application and that it was received (ricevuta). When you present your documentation, you must also present a completed JS application known as “Istanza di riconoscimento del possesso dello status civitatis italiano” with a marca da bollo (revenue stamp) for 16 Euro which is obtainable from the Tabaccheria. The clerk can get you this form but it may also be available for download online.
Non Rinuncia checks: Part of the processing of your application involves verification from the consulates over the various places outside Italy that you and your ancestors lived, that none of you ever voluntarily renounced Italian citizenship before an Italian authority. The clerk may want you to present to them a document attesting to all your places of residency and all the places of residency for everyone in your direct line of citizenship transmission. This form is used to help the clerk know which consulate or consulates they need to contact. The clerk cannot finalize your application until all these “Attestati di Non Rinuncia” or no renunciation certificates come in from abroad. Many who have attempted to apply in Italy have reported confusion over responsibilities for this part of the process. This request to the consulates must come from the citizenship officer. You cannot request these checks yourself.
