The Graduate School requires that students who withdraw (that is, who are registered during one semester and do not register for the following semester) must apply for readmission to resume their graduate work at Stony Brook. You should note that the time limitations of Section 5.3.6 are suspended only for students who are on official Leave of Absence.
If you find it necessary to interrupt your matriculation, you may ask the Graduate Studies Director to seek approval from the Graduate School for a Leave of Absence for one year (this can be renewed for a second year). You should however be aware that, after a Leave of Absence, you will need to be readmitted to the Graduate School; the conditions for readmission should be stated in the Leave of Absence Form.
