Students who must interrupt their studies may, with the approval of a program director, register for Matriculation Continued (leave of absence). There is no tuition fee for this registration, although a student fee is charged. Students who do not register for Matriculation Continued will be charged a reactivation fee upon their return to the program. (Students on temporary visas who interrupt their studies must in most cases leave the United States during such periods.) Matriculation Continued is available only to students not enrolled in any coursework and not using faculty time and university facilities, except to complete previous coursework from classes with incomplete or temporary grades. Students may enroll in Matriculation Continued for a maximum of two consecutive semesters.
