From the perspective of U.S. immigration, students transfering to UVA who have not held any student status in the U.S. are treated the same as new students.
Students already in the U.S. in F-1 status, whether in secondary or post-secondary education, must work with their current school's Designated School Official (DSO) to have their SEVIS record released to UVA. Students transferring their status to UVA must also provide documentation of continued eligibility for F-1 status including documentation of adequate funding. The I-20 from UVA cannot be issued until the SEVIS record is released, and the release date has been reached.
F-1 students transfering out of UVA must complete the SEVIS Transfer Release Form and bring it to the ISO during office hours. Transfer out requests cannot be made after the 60 day grace period following studies has been exceeded.
