As someone who grew up in India, studied and worked and the US and who spent 6 months attempting to help my previous employer set up an off site development centre at a third party vendor, before returning to the US, here is my perspective.

Management culture is not controlling or assertive in a manner any different than that practised at my US employer. The differences are mostly in response to such assertiveness, Indians tend to typically approach such assertiveness by authority with mere acceptance without necessarily understanding the reason underlying the decision. Such management assertiveness I have found to be misguided with the same rate at both locations.

Management response to highlighting inefficiencies in work culture or ineffectiveness with regards to output is specific to the organization, and in my experience I found the response to be similar, hide inefficiencies rather than work towards improvements.

I do not think I would find it difficult to go "home" (I consider US to be my home now), I would only need to find an organization that has the same first principles of continuous (personal and profession) improvement as I do.

Finding such an organization in either nation would be similarly difficult or easy.
