International migration is a global phenomenon; it is growing in its size, scope and complexity and impacts. Migration is both a cause and effect of a broader development process and it can be considered as a positive force for development, when supported by the right type of policies. Today there are an estimated 232 million migrant workers around the world. Globalization, demographic shifts, conflicts, income inequalities and climatic changes encourage many more workers and their families to cross borders in search of employment and security. These migrant workers are becoming the source of income, contributing to growth and development in their countries. It is better economic opportunities which are basically responsible for migration. The migration is beneficial to both the origin and destination countries. In the era of globalization, there are many challenges posed by labour migration. The past few decades have seen tremendous change and diversification in the nature of international labour migration. Today in the globalized economy labour migration has taken an important place.
