I am currently enrolled in a Master's program, and the Summer term (May-Aug) is considered as a scheduled break for my program. I have accepted an intern offer for this summer, and the duration is May 6, 2019 - August 23, 2019. The intern does not count toward any credits. Can I work for the intern with my study permit without applying for a work permit? Do I have to have a Co-op work permit in order to start the intern?
