Under Italian law, registering in the A.I.R.E. [which stands for “Anagrafe Italiani Residenti Estero”, i.e. a register of Italian citizens residing abroad] is a duty for Italian nationals.
More specifically, Italian law no. 470 of 27 October 1988 states that all Italian citizens who transfer their residency outside the territory of Italy for a period of more than 12 months must complete the necessary formalities to register in the A.I.R.E. before the Italian consular office having jurisdiction over the foreign place within 90 days of arrival in the foreign country.
The registration by the interested party (for himself/herself as well as on behalf of his/her family members) is a pre-requirement to access all the services issued by the competent consular offices, including the issuance or renewal of an Italian passport. That is why this is a very important thing to do, and we highly recommend that you promptly do it and keep it updated.
For Italians residing in Arizona, the competent consular office for the registration in the A.I.R.E. is the Consulate General of Italy in Los Angeles. This Honorary Consulate has no competence over AIRE registrations and cannot assist you in changing/updating your address other than by giving you basic information already available online through this link: https://conslosangeles.esteri.it/consolato_losangeles/en/i_servizi/per-i-cittadini/anagrafe
We strongly recommend to use the portal FAST IT for all services concerning AIRE such as registration/update/access to your consular file needed to renew your Italian passport etc. This is a free service available to anyone.
