Direct answer: keep passport, visa, nulla osta, residence contract or offer, accommodation proof and the application receipt. The exact list depends on the channel (ALI, postal kit or Questura). Follow the appointment instructions, prepare readable copies, bring originals and keep the protocol number. Do not mail originals unless requested.

Who this applies to: Anyone applying for a first employed-work permit who must prove lawful entry, employment and accommodation.
Practical steps: 1) collect passport, visa, nulla osta, signed residence contract and proof of accommodation; 2) complete the kit or application indicated by the Immigration Portal within the entry deadline; 3) pay only the postal forms and stamp required for that category and keep receipts; 4) submit the file and attend the photo and fingerprint appointment with originals.
Documents to keep: passport and visa, nulla osta, stay/employment contract, tax code, accommodation and filing receipt.
Verifiable timing and costs: The first application follows the entry route and deadline; stamps and contributions depend on the permit.
Exceptions and special cases: Seasonal work, single permits and other entries may require different documents or channels.
If the procedure stalls: If evidence is missing, request a written supplement and keep the correspondence before the appointment.
Practical example: The worker gathers passport, nulla osta, contract and accommodation, files the route and keeps the receipt.
