Most states require 12 months of physical presence in their states to become the resident of that particular states and get the state benefits. For example: If you want to be a resident of Minnesota and get in-state tuition, you must move to Minnesota, work there for a year to be a bona-fide resident of that states. During the first 12 months, most states will not permit you to take more than 6 credits if you want to establish residence with that states. However, some states might have different rules.
