Nulla Osta, certificate and visa D

The Nulla Osta is the migration service (Questura) no-objection clearance and one of the key documents for visa D. It is filed through the Camera di Commercio (a declaration of no obstacles) and the Questura. Community: issuance is about ~20 days by law, longer in practice. Note the validity windows - community reports often cite around 180 days to apply to the consulate, with people trying to use the Nulla Osta within roughly 3 months. This route falls under the Decreto Flussi quota, so timing matters: applying in a bad window without preparation often wastes time.

The economic-parameters certificate from the Camera di Commercio (chamber of commerce) states the balance you must show on your bank account, which depends on the type of activity (community values around ~17,000-21,000 EUR). Community: you need a passport copy, a booked appointment and two marca da bollo (~16 EUR each); readiness in about ~7-14 days, sometimes longer around holidays. Several applicants report the chamber of commerce, not the Nulla Osta, ended up being the slowest step.

Submit the visa D application at the Italian consulate covering your country of legal residence (with another country residence permit, you may apply from there). The appointment and document list are on vistoperitalia.esteri.it. All documents are translated into Italian by an accredited translator (English documents usually do not need translation). Community: the visa fee is around ~116 EUR plus the consular fee. The visa cannot be obtained inside Italy.
