DO I HAVE TO ALLOW THE OTHER PARENT VISITATION EVEN IF HE OR SHE IS NOT PAYING CHILD SUPPORT AS ORDERED?

Yes, you should not stop visitation because of failure to pay child support. Otherwise, you may be held in contempt of court. The proper way to deal with non-payment of child support is to ask the court to hold the non-custodial parent in contempt of court for failure to pay.
