The work clearance (nulla osta)
The work clearance (nulla osta al lavoro): who issues it, how employers apply through the Immigration Portal, how long it lasts and how it links to visa and permit.
Quick answer
The nulla osta al lavoro is the clearance issued by the Prefettura’s Sportello Unico per l’Immigrazione at the employer’s request, allowing a foreign worker to enter Italy. It is valid for a limited period and is used to apply for the visa at the consulate.
The clearance links the employer’s need with Italy’s entry rules: without it the consulate cannot issue a work visa.
Applications are filed online: the employer needs a digital identity and must follow the procedure on the official portal.
