Before you start

A long-stay type-D visa in your passport, for non-EU nationals
For most work routes, a nulla osta already issued to your employer by the Sportello Unico per l'Immigrazione
An address in Milan — a registered lease, a property deed or a hospitality declaration
A codice fiscale, which you can and should obtain before anything else
For EU citizens: proof of work, study or sufficient resources plus health cover

Step-by-step

1
Get the codice fiscale on day one
Apply at an Agenzia delle Entrate office with your passport, or receive it automatically at the Sportello Unico if you arrived on a sponsored work or family visa. It is free, immediate and unlocks everything downstream — leases, bank accounts, SIM contracts, the health card.

2
Collect the yellow kit and file within eight working days
Pick up the kit giallo at a Poste Italiane counter displaying the Sportello Amico sign, complete it, attach a €16 revenue stamp bought at any tobacconist, and hand it in with the postal and permit fees. Keep the receipt — it is your evidence of lawful stay and the document banks and HR departments will ask for.
In personWho: YouWithin 8 working days of entry
3
Attend the Questura appointment for fingerprints
The post office receipt carries a date for your appointment at the Questura di Milano's immigration office in via Cagni. You are photographed and fingerprinted; the card follows later. Bring the originals of everything in the kit — the Questura checks against them.
In personWho: YouTypically 1–3 months after filing
4
Register your residence with the Comune di Milano
The iscrizione anagrafica can be started online through the Fascicolo del Cittadino, or in person at an anagrafe office. It takes effect from the day you declare it, not from when it is approved, and the comune then has 45 days to verify.
OnlineWho: YouWithin days of moving in
5
Be at home for the vigile's visit
A municipal police officer calls at the address, unannounced, to confirm you genuinely live there — checking the name on the buzzer and often speaking to a neighbour. If nobody is home the officer usually tries again, but a missed check can stall the registration. Put your surname on the intercom and the letterbox the day you move in.

6
Collect the permit and diarise the renewal
The Questura publishes a status lookup and sends an SMS when the card is ready. Renewals should be filed at least sixty days before expiry, and the same postal kit process applies each time.

Things most newcomers don’t know

The eight-working-day deadline runs from entry into Italy, not from starting work or finding a flat.

People arrive, spend a fortnight looking at apartments, and only then think about the permit — by which point the deadline has passed. The clock starts the day you cross the border on your type-D visa. You can file using a hospitality declaration from whoever is putting you up, so a permanent address is not a prerequisite. Getting the kit in late is not fatal, but the Questura asks about it and it can complicate a first renewal.

Residence registration takes effect the day you declare it, while the comune has 45 days to check.

This surprises people who assume nothing counts until approved. The declaration is immediately effective, so you can request a certificate of residence, register with the SSN and apply for a health card straight away. If the comune says nothing within 45 days, silenzio-assenso confirms it. The corollary is that a false declaration is effective too — and unwinding one after a negative check is much worse than waiting.

The Blue Card and the article 27 routes sit outside the decreto flussi quota, and Milanese employers often forget it.

Most non-EU hiring in Italy is rationed by the decreto flussi, filed on a 'click day' where a year's places disappear in minutes. But highly qualified employment under the EU Blue Card, intra-company transfers, researchers and university teaching are all outside the quota entirely. A candidate whose employer defaults to the ordinary work route can lose a year for no reason. It is worth asking HR explicitly which route they are filing.

An intra-company transfer permit does not count toward permanent residence.

Time held on the ICT permit for intra-corporate transferees is expressly excluded from the five-year calculation for EU long-term residence. Milan is full of people posted here for three years by a multinational who assume they are accruing residence and discover at the end that they are not. If settling is the plan, a local Italian contract or a Blue Card gets you there and the ICT posting does not.

Common mistakes to avoid

Letting the eight-working-day window pass while apartment-hunting.
Not putting your surname on the buzzer, so the vigile cannot verify the address.
Assuming the residence registration must be approved before you can use it.
Accepting an ICT posting when settling in Italy is the actual goal.
Filing a renewal in the last fortnight before expiry rather than sixty days ahead.
