US Passport-Visa needed when you're travelling in the US?
No, all she needs to do is produce her US passport for the CBP Officer at the port of entry. She should use the "Returning US Citizens" line at the immigration check in the airport.

Is it worth it to get a passport card if you are already renewing a passport book?
It is proof of identity, age, and citizenship, does not have your address on it, and unlike a driver's license of state ID, cannot be used for identity theft. Use it when asked to prove identity at hotels, and by merchants who insist of photo ID when using credit cards.

Study Abroad Rome this fall for college Junior?
My daughter studied in Rome for a semester about 15 years ago. Then she stayed to take a Latin course in the summer, taught by a monk at the Vatican. I went to visit her at the end of the summer and we backpacked through Europe together. In a roundabout way, it all led to my meeting a nice Italian man and now we're married and I live in Italy.

Collection of Passports on Ship?
I've had to surrender my passport on several cruises in Europe, South America, Australia and even transatlantic trips. There have been occasions when they returned them to us for the port and other times we didn't get them back for a port. I always carry several copies along with social security card, birth certificate, and driver's license. Not sure what I'd need if something did happen but I carry as much ID as possible.

How does one acquire a second passport?
If it was so easy for ten thousand "false" passports to be obtained, how easy would it be for me to get one? Does anyone dare try in the interests of research?
