Furthermore, in the world, many countries have the large number of people who immigrate because of many reasons likes finding suitable jobs or new place to live.

VI. Conclusion
On the whole, I think that immigrations bring many benefits for the host countries, so they should not prohibit or decrease the number of people who want to immigrate to their countries. On the other hand, the government of these countries should to have the better laws to control immigration.
