The E-3 visa category is for Australians only. The applicant must have a bachelor’s degree or its equivalent, and the U.S. job must require a bachelor’s degree or its equivalent (making it a “specialty occupation”).
The E-3 category provides for a two year authorized stay period which can be extended indefinitely as long as the foreign national and the U.S. job continue to qualify. Spouses of E-3 visa holders are eligible to apply for U.S. work authorization.
