This page gives a broad overview of guardianship and visitation law in the US. Some states have stronger restrictions on a guardian's control over visitation, so in Tennessee only the court can remove an individual's right to communication, visitation, or interaction. Kansas does not have any such laws (art 30), so it is a power of the conservator to restrict visitors.
