The nulla osta is the document issued by Italian immigration authorities which authorizes a non-EU national to apply for a work visa at the Italian embassy/consulate in their country of residence. Depending on the type of work permit one applies for, it may be necessary to first apply for a nulla osta (e.g., in the case of an EU Blu Card for direct hiring by an Italian company, a nulla osta shall be obtained from the competent Sportello Unico per l'Immigrazione, or in the case of self-employment, the nulla osta shall be obtained from the competent Questura, Police station).
