About Migration

You may ask somebody who work in Immigration Department.

Regarding the problem of management of migration or immigration into another nation, the followings are my opinions:
1) social security problem==Firstly, usually the authority of the nation have to plan and check whether there is a tendency of shortage of newly born children within the future by means of census. Secondly, they have to plan and check if there are shortage of skillful labourers or technicians or experts or specialists in the industries or enterprises within the future by means of census. Thirdly, They have to consider whether there is a tendency of aging problem based on the result of the census.
2) Enviromental protection==Firstly,they have to lay out the plan for the city or township or commercial center etc in order to make use of land to the maximum. Secondly, they have to lay out the plan for public gardens or public parks or country parks etc. based on the ratio between building and amenity.Thirdly, they have to provide sufficient supply of water, energy and transport etc.
When all the above 1) and 2) problems are to be found in positive, then they will go ahead and accept the immigrants according to the needs; otherwise they might delay or stop such action until it is clarified.
