The E3 visa is a visa category for Australians who want to visit the United States. It is a work visa and is only applicable for people who are employed in a specialty occupation. A specialty occupation is a professional one that normally requires a minimum college degree.
To qualify for an E3 visa, the pay from the job role has to be greater than the average pay for that role. It also lasts for a period of two years but can be extended indefinitely. When you get an E3 visa, you can only work for the employer that sponsored your visa.
If there is any change in your working condition, you have to file it with the USCIS.
