Canadian visiting the U.A.E

Good day , I am a Canadian student that will be spending about 5 days in the U.A.E . A couple of days before I leave to the U.A.E from Canada, I will be receiving my papers to study in China for the summer. So , I need to apply for the visa and I wont have enough time to do so in Canada. This means that I need to apply for the visa when I arrive in the U.A.E. Is there something specific I need to know before I arrive to the consulate and drop my acceptance letter , passport and picture ? Thank you
