To travel to Italy, visitors need a visa and must submit recent photos, properly fill out forms from the Italian Embassy, and provide a valid passport. They also need to present originals and copies of flight bookings, hotel reservations, employment documents, and membership cards. If traveling within Italy, visitors will see landmarks like Venice canals if going to Venice, St. Peter's Basilica if visiting Rome, and Michelangelo's David if going to Florence. Common foods like carpaccio will also be available throughout Italy.
