US VISITORS who have been following the saga of the Bush administration”s immigration philosophy should note that with effect 5 January a new security programme will be implemented designed to serve the dual purpose of speeding the entry of legal foreign visitors whist keeping out potential security threats. The procedures will require most visitors travelling on visas to the United States to have two fingerprints scanned by an inkless device and a digital photograph taken by immigration officials upon entry at US air and seaports. And you probably will have to take off your shoes too!
