Migration is an important feature of human civilization and it‘s a global phenomenon in modern times. It has been observed that economic development has been accompanied by large scale movements of people from rural to urban areas and one district to another district, one state to another state. Migration has been defined as crossing of the boundary of a legal, political and administrative unit for a certain minimum period of time. It includes the movement of people from one place to another place in the hope of better opportunities, high standard of living, jobs etc. According to classical theories, migration is a rational decision made by an individual or group of persons to move from one undeveloped place to a developed place to gain new opportunities. There are a host of definitions ofthe term migration. Movement of persons from one state to another, or within their own country of residence, for the purpose of employment.Labour migration is addressed by most States in their migration laws. In addition, some States take an active role in regulating outward labour migration and seeking opportunities for their nationals abroad.
