Nulla Osta at Rome's Sportello Unico Immigrazione: How It Works
Everything goes through the ALI 2.0 portal and the Prefettura on Via Ostiense. Here are the types of nulla osta, the documents you need, and how not to miss the click day.
In a nutshell
The nulla osta is the authorisation that the Prefettura (regional state-government office representing the central state) — through the Sportello Unico Immigrazione (one-stop immigration desk at the Prefettura), commonly called SUI — issues to allow a non-EU national to enter Italy for work or family reunification, or to convert an existing residence permit. No nulla osta means no visa; no visa means no permesso di soggiorno (residence permit for non-EU citizens). In Rome the SUI is located at Via Ostiense 131/L and everything is handled online through the ALI 2.0 portal.

What the Sportello Unico Immigrazione is
The SUI is the Prefettura office that acts as a single point of contact for all the bodies involved in an immigration application: the Ministry of the Interior, the Ministry of Labour, INPS (Italy's social-security agency — pensions, unemployment, family benefits), Agenzia delle Entrate (Italy's tax-revenue agency), and the Questura (police headquarters — which also issues residence permits). In practice this means you do not have to visit each office separately; you submit everything online and the SUI gathers the opinions it needs from the other agencies.
The SUI nulla osta is the final document certifying that the employer or applicant meets all legal requirements and authorising the Italian Consulate in the applicant's country to issue the visa. Once the foreign national is in Italy, the nulla osta is also used to sign the contratto di soggiorno (residence contract) at the Prefettura and to then apply for the residence permit at the Questura.
Types of nulla osta
| Type | Who applies | Subject to Decreto Flussi quota |
|---|---|---|
| Employed work | Italian employer | Yes — click day only |
| Self-employed work | Foreign national | Yes — click day only |
| Seasonal work | Employer | Yes — click day only |
| Family reunification | Foreign national already resident in Italy | No — open all year |
| Conversion (e.g. student → work permit) | Employer or applicant | Yes (in a dedicated quota) |
Some categories are outside the quota system and can be submitted at any time of year: scientific research, EU Blue Card, intra-company transfers, professional athletes, performing artists, and domestic workers accompanying Italian employers.
Documents: common requirements and type-specific extras
Every type of nulla osta has its own document list. These are always required:
- Valid identity document of the applicant
- Codice Fiscale
- Form completed online on the ALI portal
- €16 marca da bollo
For an employed-work nulla osta, add: Modulo A (draft residence contract / proposta contratto di soggiorno), company chamber-of-commerce extract (visura camerale), balance sheet or tax return, DURC (certificate showing the business is up to date with social-security contributions) in current validity, copy of the worker's passport, and a housing declaration.
For a self-employed-work nulla osta: Chamber of Commerce attestation of professional requirements, proof of financial resources, professional credentials (professional-register memberships, qualifications).
For a family-reunification nulla osta: the applicant's current residence permit, certificate of residence, housing-suitability certificate (certificato di idoneità alloggiativa, issued by the Municipio or the ASL — Azienda Sanitaria Locale, your local public-health authority), proof of income, and kinship documents translated and apostilled or legalised.
How to apply on the ALI 2.0 portal
Step 1 — Register. Go to nullaostalavoro.dlci.interno.gov.it and log in with SPID (Italy's digital identity for accessing online public services) or CIE (Italian electronic ID card). Foreign employers who do not yet have SPID can request dedicated ALI credentials.
Step 2 — Select the right form. Choose the form that matches your type of nulla osta: Modulo A (employed work), Modulo B (self-employed), Modulo BPS (seasonal), Modulo S (family reunification), Modulo V (conversion), Modulo Z (special cases under art. 27 TUI). Fill in all fields, upload your PDFs, and save the draft — you can edit it up until you submit for real.
Step 3 — Submit. For nulla osta applications subject to the Decreto Flussi (annual quota decree allocating non-EU work visas) you must submit exactly on the click-day date and time: applications are assigned in order of arrival until the quota runs out. Prepare everything days in advance; on click day all you do is press "submit". Family-reunification applications can be sent at any time of year.
Step 4 — Assessment. The SUI checks your documents, the available quota, the employer's eligibility, and whether there are any grounds for refusal. It can request additional documents through the portal — respond immediately, as delays slow down the whole process. Legal deadlines: 60 days for work and conversion applications, 90 days for family reunification. Real-world timelines in Rome: 3–6 months for work, 4–8 months for family reunification.
Step 5 — Collect the nulla osta. The SUI contacts you via the ALI portal or PEC (certified email — legally valid in Italy). For family-reunification cases the SUI often transmits the nulla osta directly to the Consulate.
Step 6 — Visa at the Consulate. The foreign national presents the nulla osta at the Italian Consulate in their country and obtains the visa within 30–90 days. The visa is valid for 6 months and allows a single entry.
Step 7 — Arrival and residence contract. Within 8 days of entering Italy the foreign national must appear at the SUI together with the employer (for work cases) to sign the contratto di soggiorno. The Codice Fiscale is generated automatically by the ALI portal at the time the nulla osta is issued and will appear on the contract.
Step 8 — Residence permit at the Questura. Within 8 days of signing the contract the worker collects the yellow kit at the post office or through a Patronato (free union-run office helping with social-security and immigration paperwork), hands it in at a Sportello Amico post-office counter, and then attends the Questura (Via Teofilo Patini 23) for fingerprinting. The electronic permit is sent by SMS when ready.
Mistakes to avoid
- Missing the click day. Quotas run out in minutes. Prepare all your documents and your draft well in advance — on click day you only need to hit "submit".
- Uploading documents not in Italian. Everything uploaded to the portal must be in Italian — Italian originals or sworn translations. PDFs must be legible and complete.
- Not monitoring your PEC inbox. The SUI sends appointment notices and requests for additional documents via PEC. Miss a message and you risk missing a critical deadline.
- Using a fictitious employer. This is a criminal offence under art. 22 c. 12 TUI and results in criminal charges and cancellation of the nulla osta.
- Failing to appear at the SUI within 8 days of arrival. Missing this deadline can invalidate the entire procedure.
Special cases
Application rejected. The SUI sends a reasoned refusal. You have 60 days to appeal to the TAR Lazio (regional administrative court) or 120 days to file an extraordinary appeal (ricorso straordinario) to the President of the Republic. The most common grounds for rejection are: incomplete documentation, income below the threshold, unsuitable housing, quota exhaustion, or a negative opinion from the Questura.
No response within the legal deadline. In some circumstances the silence can be treated as tacit approval (silenzio-assenso), but the safer course is to follow up via PEC. Constructive refusal (silenzio-rigetto) allows you to appeal to the TAR.
Employer changes after the nulla osta is issued. If the employer changes between the nulla osta being issued and the worker arriving in Italy, the nulla osta lapses and a new one must be requested, unless the change results from a company merger or acquisition.
Three-year Decreto Flussi 2023–2025. DPCM 27/09/2023 set a total quota of 452,000 entries distributed across annual click days. Keep an eye on the Gazzetta Ufficiale (Italy's official government gazette) and the Ministry of the Interior website for exact dates.
