US Immigration – A Guide for Employees: "E-3 Visa for Australians
In 2005, the US announced a new visa called the E-3, for Australians only. The E3 visa allows Australian nationals, along with their spouses and children, to come to the US to work in a specialty occupation.
This should be welcome news for Australians interested in working in the US. Until now, Australians have had to battle it out with others around the world for the highly desired H1B Visa. Last year only 900 Australians obtained an H1B - now Australians have 10,500 E3 visas just for themselves. A specialty occupation is one that requires a body of knowledge in a professional field, and at least a bachelor's degree or its equivalent, as a minimum for entry into the occupation in the United States. For Australians interested in the E3 visa, the process is actually quite similar to the H1B visa. You must first find a job with a company who will then sponsor your visa. There are 10,500 E-3 visas available per year.
Spouses of an E-3 visa holder are permitted to come to the US and work also. A spouse's employment may be in a position other than a specialty occupation."
