With an Italy Tourist Visa, you can stay in Italy for up to 90 days within a 180-day period. This means you can travel and remain in Italy or other Schengen countries for a maximum of three months in total. The 180-day period is counted from the date of your first entry. You cannot stay longer than 90 days unless you apply for a different type of visa. Always check your visa sticker to confirm the exact number of days granted.
