Immigration refers to the displacement of people from one region to another.  This is the condition when the person needs to settle down at a new place to which he o she does not belong. This requires the possession of a Visa that serves as a legal document stating that the person is now permitted officially to live there. The reason of immigrating could be many things. This could include the occurrence of a natural disaster or some political issues or it could also be for economic flourishment.

Reasons for Immigration

One of the most important reasons that lead to immigration is the push factors. This is primarily caused due to the differences in wage rates in different regions. This disparity caused results in people moving from one place to another in search of economic prosperity. This was particularly observed during the nineteenth century when the economic expansion in the United States attracted a large number of immigrants to this place. Especially, if immigrants come from low developed counties, it would result in a far better standard of living and influx of more resources.

Pull Factors

The pull factors included the cost of settlement in the new place. The cost included a lot of other things like the cost of travel from the native place, the loss of work time and a lot more. This was certainly very difficult before but with the technological advancement, it is far easier now to travel around the globe than before. In the eighteenth century for instance, the time duration for travelling across the Atlantic was around five weeks, however it reduced to just eight days, in the twenty century time.

Immigration due to poverty is one of the prime contributing push factors that facilitate immigration, whereas the incidence of employment and jobs is one of the contributing pull factors in this state of welfare. One of the other important contributing factors is the incidence of natural disasters. However, this is not a legal form of immigration. It is considered illegal as it reduces the economical welfare as the per capita income and national income of the immigrant country reduces on the influx of people who are just seeking refuge without any kind of desire to work. Education is also another pull factors for immigration. There are international students who migrate to new places in search of good educational facilities.

Retired Immigration

Another form of migration could be retirement migration. This would mean the influx of people from rich countries to lesser prosperous places in the lookout for a better climate and an economical standard of living. There are various incidences of these that could be cited as examples. Here, examples would include the migration of retired British officials to Spain and Italy, and that from Canada to the United States. There are certain laws framed in order to protect the interests of both the immigrants and that of the people and the place the immigrants are migrating to. This helps in making the process easier.
