Abstract:

Migration of foreigners is more and more mentioned and dreaded topic recently. There is a lot of independent theories, present or past, that tried to explain migration according to different fields of study. Each theory explains some type or aspect of a migration according to an event and an epoch when it was created. These theories can be distinguished mainly by what is considered as the main reason and by which questions they are looking for answers. We can say that there is no integrated theory that would cover all of migration theories because each branch of science provides different sight on this term. As there is so many different theories we will deal only with a couple of them.
