Thanks in advance

Can one shift to department which is not the same as thier undergraduate department??.

Yes, you can totally shift the degree majors in USA. You would be required to do all the pre-requisites though.

It depends on the school. Some requires all of the prerequisites to be done as full time. Some provide few waivers. You do NOT have a choice, if you want to change majors.  The good part is that you will get the Stats and Alegbra classes waived. You would need to take some programming classes, again it depends on school. if you are passionate about MS in CS, then go for it.
