Emigration is the action and the phenomenon of leaving home to settle in another country, for political or economical reasons.
Emigration sometimes for life, and families move together toward new regions or new countries where they hope they can find job opportunities which are not available in their originary location. Throughout history a large number of emigrants return to their homelands, usually after tey have earned sufficient money in the other country.
Frequently, emigrants will always feel as guests in their destinations, and will preserve originary culture, traditions and language, sometimes transmitting them to their children. The conflict between the native and the newer culture may easily create social contrasts, generally resulting in an uncomfortable situation for the "foreigners", who have to understand legal and social systems sometimes new and strange to them. Often, communities of emigrants grow up in the destination areas, collecting immigrants of common provenance, also to help for integration.
