After you have been formally admitted by Graduate Admissions
You will need to complete the "Intent to Enroll" by the specified deadline.
Watch your WebPortal account for information about the date by which you need to pay your fees, and your assigned date/time to register for classes via WebPortal.
(Note: The date/time assigned to you is the first possible moment that you may register; if you cannot register at that exact time, please note that you may do so at any point after that time, up to the end of the regular registration period.)
Graduate Admissions will notify Financial Aid of your admission. If you have applied for financial aid, you will hear from that office concerning your financial aid package.
