The migration is defined as the act of settling in a place other than the place of origin or that had been previously, for reasons, mostly, social or economic. The favorite settlement points of the emigrants are the countries of the first world, which suppose great job opportunities and consequently, better economic forecasts. Likewise, there is the condition of "exile" , in which a certain subject is forced to leave the nation, usually due to political problems.
Throughout the history of humanity there has been talk of emigration, taking as an example one of the first mass mobilizations of ancient settlers that is known, in which they fled to areas that maintained a warm climate at that time on the planet, due to the great drop in temperatures that triggered the ice age.
During the periods of war, the inhabitants of towns that participated in it, migrated to safe places, so as not to perish during the raw confrontations between rival gangs. Such is the case of the First and Second World War, in which an anguished community fled to other places, for only a hope of life; panic was present every minute when an invasion or confrontations was announced. Meanwhile, in ancient times, mobilizations were carried out for religious reasons, such as the expulsion of a movement of beliefs other than those already established by the rulers of the cities.
Nowadays, emigration is one of the best options that some individuals may have when launching themselves in the search for new horizons and opportunities. However, it would be necessary to go through large naturalization processes, in order to exercise a settlement that is within the legal framework.
