what rights does a mom have with visitation rights

There is not nearly enough information there to provide a meaningful response.  Where was the initial order entered?  Who moved where to create the current conditions?  Have these facts been reviewed by a court previously? You can start with the information posted at http://willicklawgroup.com/child-custody-and-visitation/ but you are going to need to speak with a lawyer in whatever State has jurisdiction over the case to determine what, if anything, an be done, and how to do it.
