From the NCAA, among some other announcements:
Moving forward, prospects will no longer have a limit to the number of official visits they can make to NCAA member schools. Prospects will be limited to one official visit per school, unless there is a head coaching change after an official visit, in which case prospects would be able to complete a second official visit to the same school. In men’s basketball, prospects still will be able to complete a second official visit to the same school provided the visits do not occur in the same academic year.
