Best Public school New Jersey

Rutgers is generally regarded as NJ's best public university, so I assume that its MBA program is the best one in the state.

You aren't getting in-state tuition privileges at any public university unless you lived in that state for at least a year and CLAIM RESIDENCY there. Probably not happening for a full time program if you're moving to the US to get the MBA degree.

In-State tuition rates at many MBA programs aren't as deeply discounted as they used to be either, because many universities have privatized them, so in state students only get a nominal discount over out of state students. UVA and Michigan are examples of public universities that have privatized the graduate business schools, and therefore, in state students don't have much of a tuition advantage. Then again, UVA and Michigan have very highly regarded MBA programs at Darden and Ross which are world class so you can still argue that the ROI will be great with an MBA from there.
