International Internal transfers

Microsoft has a policy that an employee has to be at a certain level (say X) before they can apply for an international role internally. The weird bit is that this policy is applicable to Indian (MSIDC) employees only. No other country office has such policy. From what I’ve seen so far, X level is attained around 5 yrs of experience. By that time a typical Indian employee has other commitments in life and the number of employees willing to take international transfer decreases.

I feel it this policy is strategic to keep their business needs in India stable.

Thoughts? Do any other companies have any such policies?
