Other Employment-Based Options Information for HR/Partners/Department Administrators

While the J-1 and H-1B categories are most commonly used for international employees at UC Denver, we also host international employees in the TN, E-3, O-1, F-1 Optional Practical Training, F-1 Curricular Practical Training, and J-1 academic training visa categories. International employees who have an Employment Authorization Document issued by the U.S. Citizenship and Naturalization Service can also be employed by the University. 

TN: Treaty NAFTA

  • Used for Canadian & Mexican citizens
  • The position must align with the list of professions in the treaty
  • Cannot be used for clinical faculty
  • The International Scholar Services unit needs to be notified when the scholar travels and returns with new expiration date on their I-94 card

E-3: Australian Professionals

  • Overview for Australian Professionals
  • Similar to the H-1B category because ISS needs to do the PW and LCA
  • Similar to the TN category because it does not need a USCIS petition if the employee is outside the USA and will gain status via consulate processing
  • Can be used for clinical faculty
  • The International Scholar Services unit needs to be notified when the scholar travels and returns with a new expiration date on the I-94 card because ISS must keep the LCA current
