Students must hold full-time status during the academic session prior to, as well as subsequent to, their scheduled break. Each scheduled break should not be more than four months consecutively and students are not eligible to work full-time if the institution allows for back-to-back scheduled breaks. Essentially, taking into account reading breaks and the winter holiday, students may only work off campus on a full-time basis for no longer than five months during each calendar year (e.g., working full-time for four months consecutively during a scheduled break plus full-time during reading breaks that generally do not exceed one week at a time).
