So which authority would handle the application, what would need to be filed, and how early would the production, uh, need to begin?

So the work permit application is filed with the Entertainment Sector Office of the Italian Ministry of Labor and Social Policies in Rome.

Applications are still paper-based and must be delivered in person by an appointed representative.

The main supported documents include the application form, powers of attorney or representation mandate, the signatory's identification, foreign employer declaration, company registration certificate, financial documents, evidence of professional qualifications, where applicable, and Anne's passport.

Timing depends partly on the length of the shoot.

For a stay under 90 days, a US citizen such as Anne would not need an entry visa, and the work authorization application would technically be requested after arrival.

She could not begin filming until authorization had been issued.

Where would she begin with an application like this? You know, what documents would she need? What would happen once the initial clearance was also issued?
