I don’t think you will be qualified for in-state tuition during the first year (and possibly not the second year) when your parents move to California.

Besides, housing cost in California is expensive. Can your family afford?
If CMU cost of attendance for you is $30,000 then that amount would be the same when you become in-state resident in CA.
Take CMU.
