If you must leave school temporarily for a valid emergent reason, you need to complete a leave of absence/withdrawal form and receive an approval from the Office of International Students and Scholars. It is essential for you to note that Immigration (USCIS) sets strict procedures for international students who need to withdraw or take a leave of absence. If you do not comply with these requirements you risk a loss of your immigration status.
Students who take a leave of absence or withdraw from the University for valid non-medical reasons with the approval of the OISS are required to depart the United States within 15 days of approval.
