A bricklaying student from Silver Trowel, a leading provider of quality education and training in the building and construction industry, apprentices （当学徒） on a building project in Western Australia, where workers are in short supply．

　　Daniel Davila, a 23-year-old floorer from Camarillo, California made the 14-hour move across the Pacific two years ago．He had been forced to take a job stocking shelves at a local grocery store for $8．90 an hour when he couldn’t get work fixing floors．

　　On a good day in Australia, he now makes as much as 50 Australian dollars （US$50．21） an hour—about twice the amount for a typical flooring job in the U．S．He plans to start his own flooring business．

　　“I can make what I did in a week in the U．S．in less than a day here,” said Mr．Davila, who lives near a mining boom town in Western Australia．

　　Australian government figures show just under 7,000 Americans currently working on long-term visas, an 80% jump over the past five years．U．S．citizens are now the third-largest group applying for so-called 457 work visas, after British and Indian nationals．Americans with degrees in areas such as accounting or mine engineering, as well as other skilled workers, can obtain a nonrenewable（不可续期的） permit for as much as a three-year stay．After that, they can apply for the renewable 457, which allows up to a four-year stay．
