Passports and Visas
Before your first taste of authentic crostini misti and a glass of Chianti, you'll have some paperwork to do. Check to see that your passport is current, and remember that returning to the United States with an expired passport is illegal.
Visas are generally required for citizens of the United States only if they stay in Italy for longer than three months. If that's the case, you'll need an application form, a detailed itinerary, proof of adequate medical insurance, a valid return airline ticket, and proof of accommodations.
Also carry two or more forms of identification on your person, including at least one photo ID. Many banks require several IDs in order to cash traveler's checks.
Fact
Freedom of movement isn't just for those wearing stretch pants. If you're an EU citizen, you can take the specially designated lane at the airport and breeze right through customs. It's all part of the efforts to ease border-patrol regulations and ease travel between participating countries.
Customs
Going through la dogana (customs) shouldn't be much of a bother as long as you have all the right identification. In addition, if you've purchased goods and gifts at a duty-free shop, you'll have to pay a duty if the value of those articles exceeds the allowance established by the Italian customs service.
“Duty-free” simply means that you don't have to pay a tax in the country of purchase. Be sure to keep receipts for major purchases while in Italy — non-European Union citizens can claim a refund for the value added tax (VAT or IVA).
