Returning from a Leave of Absence (Less than 5 Months)

If the gap in your enrollment will be fewer than five months, OIA can usually request that your F-1 status is 'reactivated' by USCIS. Reactivation allows you to maintain your OPT/CPT eligibility and use the same I-20 and visa (if not expired). 

Note that OIA can only request that your record is reactivated.  USCIS approves the actual reactivation and often requires additional documentation from the school and the student to make the change.
