In short. If you have a wrong Decreto Flussi Nulla Osta, check the first name, surname, date of birth, passport number and passport expiry date straight away and report the error promptly to the Sportello Unico per l’Immigrazione (Immigration Desk). The correction procedure depends on the stage your application has reached and on the instructions of the Sportello Unico and the Consulate.
What if the Decreto Flussi Nulla Osta is wrong?
A mistake in the worker’s details can prevent the visa from being issued correctly or slow down the procedure. The details in the nulla osta (work/entry clearance) come from the information entered in the application under the Decreto Flussi (Italy’s annual decree setting quotas for foreign workers). That is why it is important to compare the document straight away with the passport and with the receipt sent through the Portale ALI (the Interior Ministry’s online application portal).
What is the Nulla Osta for employed work?
The Nulla Osta is the decision by which the Sportello Unico per l’Immigrazione authorises entry for seasonal or non-seasonal employed work. The document is then forwarded to the competent offices for the visa procedure that follows.
First name, surname, place and date of birth, nationality and passport details must match the worker’s own document.
Which errors need to be corrected?
- first name or surname that does not match the passport;
- wrong date or place of birth;
- incorrect passport number, date of issue or expiry date;
- incomplete nationality or personal details;
- information about the employer or the employment relationship that does not match the application.
How do you request a correction of a wrong Decreto Flussi Nulla Osta?
The mistake must be reported promptly through the channels indicated in your application. Depending on the stage of the procedure, you may need to coordinate with the competent Sportello Unico and with the Italian embassy or consulate.
- compare the Nulla Osta, the application receipt and the passport;
- prepare a legible copy of the correct document;
- report the error to the Sportello Unico through the channel indicated in the notice or on the Portale ALI;
- if the visa procedure has already started, also follow the Consulate’s instructions;
- keep receipts, PEC (certified email) messages and reference numbers for all the communications you send.
There is no standard timeframe for every correction: it depends on the type of error, the stage of the application and the offices involved.
How long is the Nulla Osta valid, and how urgent is the correction?
The Nulla Osta is valid for a limited period. The correction request should therefore not be put off, especially if the visa appointment has already been booked or the document is close to expiring.
A correction does not automatically guarantee that the visa will be issued: the checks required by the procedure still apply.
How can you avoid errors in the application?
- copy the details directly from the passport, without adapting names or transliterations;
- check the preview before the pre-filling phase closes;
- check the form, the category and the employer’s details;
- after submitting, immediately compare the receipt with the original documents;
- check the Nulla Osta as soon as it becomes available.
To check forms, requirements and documents before submitting, read our updated guide to the Decreto Flussi 2027 application and the Decreto Flussi 2027 pre-filling dates and click days.
Frequently asked questions
I noticed the mistake right after the click day: can I report it?
Yes, you should report it straight away. However, what can be done depends on the status of the application and on the functions available on the Portale ALI or indicated by the Sportello Unico. The click day is the date on which Decreto Flussi applications can be submitted online, so compare the receipt with the passport immediately.
How long does it take to correct the Nulla Osta?
There is no guaranteed timeframe. It depends on the type of correction, on the Sportello Unico and on whether the Consulate also needs to be involved. Because the Nulla Osta is valid for a limited period, the request should not be put off, especially if the visa appointment is close.
Can I get the visa with details that differ from my passport?
Any discrepancies between the Nulla Osta and the passport must be resolved before the visa procedure is completed. You need to follow the instructions of the competent Sportello Unico and Consulate. Even after a correction, the visa is not issued automatically: the checks required by the procedure still apply.
Which details in the Nulla Osta should I check?
Check the first name and surname, place and date of birth, nationality, passport number, date of issue and expiry date, as well as the employer’s details and the employment relationship. All of this information must match the worker’s passport and the application submitted through the Portale ALI.
