This might provide some advantages in organizing your branch, for example if you want to expand branch activities to multiple faculties. Also, Societies may offer different kinds of support for student branch chapters. A branch chapter can be a good contact point with the IEEE societies – for technically oriented events, you might be able to get support from the societes easier if you are organized in a chapter.
