A Designated School Official (DSO) is a staff member at an educational institution responsible for overseeing international students' compliance with U.S. immigration regulations. The DSO helps students maintain their visa status, provides guidance on enrollment, and assists with any necessary paperwork related to their studies in the United States. The DSO plays a crucial role in managing the Student and Exchange Visitor Information System (SEVIS), which tracks international students. They also serve as a point of contact between the school and the U.S. Department of Homeland Security, ensuring that students receive the support they need while studying abroad.
