Large number of skilled workers left Iran in the early 21st century, primary because they sought more skilled opportunities in countries like the United States.

Explanation:

Iran is a powerhouse in the Middle East, being the largest and probably the most powerful military country. The economy and the opportunities for the people in it are not so shiny though. Even though the economy seems to be relatively stable, the problem is that the opportunities in it are very limited. The reason for this is that Iran's economy only focuses on few things, while the other sectors are neglected, so many people are either working in fields they don't want to, or don't work at all.

Lot of people that had certain skills left the country because of lack of opportunities, or being under-payed.The Western countries, such as the United States were seen as very attractive as they were able to make careers there and work in accordance to their skills.The trend of migration out of Iran by skilled workers toward the West still continuous and it seems that it will do so until the country solves its issues.
