Communication Minor

I’m trying to plan out my schedule for next semester, and a communication minor sounds interesting (I haven’t declared a major yet; working on that). However, communication is offered in CALS and I’m in Arts & Sciences. I know a lot of the time you can minor across colleges, but certain subjects are just for students in that college. I’ve searched everywhere and can’t find anywhere that details who can minor in communication. Does anybody happen to know if a CAS student can minor in it, or know where I can find the information? Figured I would ask here first before bugging my advisor!
