Just want to share my perspective as an Indian who was in US for 6 years until I came back to India a couple of months back. I am not sure why you think companies can bring folks from other countries (India in your example) at a meagre salary of $25K per year and that too in a managerial capacity. You are directly questioning the work that folks at USCIS do. I was in US on L1B initially, which is different from L1A that you are referring to, and then converted to H1B and I believe I was paid a fair market wage all along. I know there could be exceptions but don't think this can happen at a scale at which you are projecting. Also, I agree that the definition of management can be stretched but don't think the wage parity can escape the authorities.
