The E-3 classification applies only to nationals of Australia. You must be coming to the U.S. solely to perform services in a specialty occupation requiring theoretical and practical application or 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.
There is a nationwide annual cap of 10,500 initial E-3 applications.
Dartmouth will sponsor senior researchers and professional staff for E-3 status if the offered position meets the regulatory criteria for a specialty occupation. The position must require a degree in a specialized field of study to successfully perform the job duties. The offered position must be full-time and benefits eligible.
E-3 status is granted in two-year increments and can be extended through the filing of a petition with USCIS in two-year increments.
Dependent spouses and children under the age of 21 may be eligible for dependent E-3 status regardless of nationality. Spouses may apply for work authorization to USCIS after arrival in the United States.
