Yes. Neither Form I-821D nor the instructions ask renewal requestors for information about continued school enrollment or graduation. The instructions for renewal requests specify that you may be considered for DACA renewal if you met the guidelines for consideration of initial DACA, including the educational guidelines and:
Did not depart the United States on or after August 15, 2012, without advance parole;
Dave continuously resided in the United States, up to the present time, since you submitted your most recent request for DACA that was approved; and
Have not been convicted of a felony, a significant misdemeanor or three or more misdemeanors, and are not a threat to national security or public safety.
