I would recommend Alpha to use geocentric approach. this is when a company adopts recruiting the most suitable individuals for the positions available, irrespective of their nationalities. most international firms uses this approach because it involves global integrated business plan. If Alpha's US-based support team requires a star performer who is presently operating in the India production office, the HR can bring him over in compliance with the geocentric model. Alpha can employ all of its talent where it is most required by using every office as a resource for the others.
nice reply.
Agreed
