They have to look at why they were denied. The most common reason for denial is that immigration did not believe that their relationship was real. They would need more proof of their relationship for the appeal. If they were still denied, his wife should go live with him in India for a year and then apply again. Appeals often take around a year. If his wife was to move to India to be with him now, it would strengthen their appeal application.
