A Visit Visa lets you stay in Italy for a maximum of 90 days every 180 days. This rule covers your whole time in the Schengen Area, not just Italy. Even if you go to different countries, the total stay can’t be more than 90 days. How long the visa is good for and how many times you can enter depends on why you're traveling and your past travel record. Staying longer than allowed can lead to punishments like fines or being blocked from coming back to the Schengen Zone.
