It can take up to 90 days for USCIS to process an OPT application so plan accordingly. If you plan to travel after graduation, an early application will ensure your smooth return for employment.
Graduating students must properly file their OPT Application with USCIS no earlier than 90 days prior to the program end date and no later than 60 days after the program end date. Please note that if you depart from the U.S. during the 60 day period, your eligibility to apply for OPT ends upon your departure from the United States.
