Brain drain means to drain meritorious and skilled persons to another country. Lured by the charms of developed countries bright boys and girls leave their poor native lands and go abroad and after finishing their higher studies settle theirs. Often expert doctors, scientists, engineers go abroad and work there for fat salaries and better service conditions. Owing to this brain drain the home country becomes the loser as it is deprived of the services of its better people. This happens when these people settle there permanently. But if they work there for a limited period and send money to their native land then the country is benefitted by getting foreign exchange. And if the intelligent and skilled people leave the country for good then the poor native land becomes poorer indeed by losing its better sons.The effective step should be taken to stop brain drain.
