Immigration
Immigration is the move from a nation to a different country, whereas he is not a citizen. Immigration refers to the permanent migration of immigrants, although tourists and travelers for short periods of time do not consider immigrants. However, migration of seasonal workers is often regarded as an immigration form. The UN estimates that approximately 190 million international immigrants in 2005, about 3% of the world's population. They also reside in their own country of birth or in their country of residence. Although human migration has been thousands of years, modern immigration concepts, especially in the 19th century, are associated with the development of nations with clear nationality, passport, perbatasan perbatasan, and citizenship law. Citizenship of a country gives special rights to the country's territory, while immigrants are being restricted by immigration law.
