How long is the Italy Self-Employment Visa valid, and can the residence permit be renewed?

The self-employment visa itself is issued for a maximum of one year, and you must enter Italy and convert it into a residence permit. The residence permit for self-employment is typically issued for one or two years depending on your situation.

Renewal is possible as long as you continue to satisfy the requirements that justified the permit, such as carrying on your activity and maintaining sufficient income. Keep clean records of your business activity, tax position and earnings, because these are what the Questura reviews at renewal.
