Since your wife's HR clearly states that they only requires her visa copy. I also presumed that if this is her first opportunity to work they also requested an NOC from you stating that you have allowed your wife to work with XXX company. This is a requirement by the labor department after that they will proceed with registering your wife under their work force but please remember that she is still under your sponsorship and maintain her status unless you agree to transfer her under the company's name.
