I have visa 20 how can i transfer of visa 18

We would like to inform that referring to the Kuwaiti residency law and with regard to the conversion of the visa of Article 20 relating to domestic workers in Kuwait first and forests conversion to Article 18 work in the private sector the server must have spent at least one year in the service of the employer in addition to the transfer must have the same sponsor or a relative of the first degree resident only, but currently unfortunately prevents the transfer so must leave Kuwait and return a work visa on the private sector.
