This will be incorrect assumption. Most Iranian students who are among the best studies in West. They are more fit for Western Corporate culture. unless Iran fundamentally get richer that can absorb much richer diaspora it will be hard to settle this contradiction. and Iran despite so good in education cannot make basic progress in management of oil and gas. It has to cut supplies to Iraq and Turkey.Iran is just in a place where China was like 10 years ago and Russia 5 years, where most people rather life in the more stable global north. But look at China now you would be a loser if your Chinese and go to the west as some sort of loser back home. Russians got a mental shock therapy last year with everything the west threw at Russia.
I wouldn't be surprise if in 2030~2035 Iran will be a completely different country with investment into infrastructure and its energy sector from China and Russia.
Russia have very little international student exposure to West and those who studied there. They simply not adjusted in Russian corporate system unless they bring specific skills and that for limited time. This culture of redundancy comes from Aviation where things are built and maintained in all directions.
This thing is also reflected in Russian economic policies of Gold that started decades ahead along with investments in Arctic.
