Schools make rules, states don’t. Most colleges require a lot more for a second bachelors (usually a minimum of two years extra work). For example, if you already have a B.A. in History, and want to get one in Political Science (or more likely, a B.S.N in Nursing, and a B.S. in Biology). If you are earning them simulaneously from the same school, they usually give the higher degree, with a double major.
If you are earning credits from two different colleges (or a college and a yeshiva that is structured to give credits), it is up to each school. Typically the university doesn’t recognize credits that count for someone else’s degree, and usually restrict the number of credits that can be transferred – and rarely accept credits at a different school taken after you started at the first school unless you asked permission in advance and had a good reason not to take the course at the first school.
