E-3 status is used for Australian nationals who will perform services in specialty occupations on a temporary basis.  At Emory, it can be used to bring faculty, researchers, or other highly specialized professionals to the US.   The employer may request a period of 2 years at a time.

To qualify for E-3 status, the scholar must already have the degree, certificate, or license that enables one to practice in the profession in the state of Georgia, if applicable.

Keep in mind that E-3 is a temporary non-immigrant status. The scholar must be coming to fill a position temporarily, although the position itself may or may not be temporary.
