In the OPT application:advisor's notification of my Univthere, there is a statement--"students on post completion OPT are not allowed to enroll full time during the benefit period"

Although I found online from NYU's webpage "you may switch employers or hold multiple employers while on OPT" http://www.nyu.edu/osl/oiss/legal/employment/f1/post_3.html
