What are the requirements to obtain a nulla osta for an Italian self-employed visa?

I will be applying for a self employed visa in Italy when the decreto flussi opens. I know the first step is to obtain a nulla osta, but I can’t find information about what I need to bring with me to the Sportello Unico to get one. What documents do I need to bring? Do I need to go in person or can I send someone already in Rome on my behalf?

Given that the "decreto flussi" is not open yet, you'd better wait till the law sets the legal requirements before applying for your self employed visa in Italy. The procedure should be the same as the latest "decreto flussi" but it is not certain. However, I can say that you have to provide the "Sportello Unico" with a valid passport and all the information related to your job, and you have to be present only at the moment of the formal entry.
