The E-3 classification applies only to nationals of Australia, who are coming to the United States solely to perform services in a specialty occupation. The specialty occupation requires theoretical and practical application of a body of knowledge in professional fields and at least the attainment of a bachelor's degree, or its equivalent, as a minimum for entry into the occupation in the United States.
To qualify for an E-3 visa, the Autralian citizen must:
Be a national of Australia
Have a legitimate offer of employment in the United States
Possess the necessary academic or other qualifying credentials
Will fill a position that qualifies as a specialty occupation
Family of E-3 Visa Holders, spouse and unmarried children under 21 years of age are entitled to the same E-3 classification. Spouse is entitled to work authorization, but not children.
