The O-1 classification applies to an individual who has extraordinary ability in the sciences, arts, education, business or athletics, which has been demonstrated by sustained national or international acclaim, and who is coming to the U.S. to work in the area of extraordinary ability. The services the individual will perform must involve a "temporary" event or project, such as a scientific project or academic year.
The E-3 classification is designed for Australian nationals to work in the U.S. in a “specialty occupation” under the Australia-United States Free Trade Agreement. A specialty occupation is one that requires a specialized body of knowledge and the attainment of a college degree. All UC Davis Departments who wish to use this category should download the E-3 package.
E-3 workers are granted status initially for two years at a time, with an unlimited number of extensions.
Services for International Students and Scholars (SISS) serves approximately 2,200 UC Davis international scholars from nearly 100 countries. The scholar community includes short-term visiting scholars and postdoctoral scholars, and full-time career researchers and faculty.
