People have so many reasons why they force to move from one nation to another nation. The reasons behind this movement are employment opportunity, economic, education, globalization, and political or environmental condition. Migration is classified as 'push factor' and 'pull factor.' Push factors force people to migrate; for example, unemployment, lack of infrastructure (such as hospital, education institutions, etc.), natural disasters (such as floods, droughts, earthquakes, cyclones, etc.), local conflicts, war, etc. The people get experience of life and move one place which gives them good life. Pull factors attract people from different places, such as better opportunities for education and employment, better health facilities, and various sources of entertainment.
