What sort of special training do overseas candidates need?

overseas candidates need more training as compared to local becouse they are not aware of the norms,values,customs and tradition in and outside office.as a trainer you should work out on that so that they can mould their skills to the best interest of the organization 

Can build a management training institution which the administration estimated actual requirement for training, based on annual plans can be used with qualified staff working in the same company staff training internally and will not be here any need for external training
