Services for International Students and Scholars (SISS) provides a range of services designed to facilitate and support UC Davis' international exchange activities.  Each year UC Davis hosts more than 2,000 international students and more than 2,500 international faculty and researchers from more than 117 countries.  Our job at SISS is to assist those departments that invite these international visitors to join them in their work. Reporting to University Outreach and International Programs, SISS provides a range of services to departments and scholars.
