i only
i, ii, and iii
i, iii, and iv
ii, iii, and iv
i, ii, iii, and iv

The correct answer is - I, III, and IV.

- The prosperity of the host nation;

This is something that can go either way, depending on how well is the migration planned by the host country and how it will manage to integrate the migrants. For example Sweden; the migration wave in the 90's from the Balkans, was not that massive, and the migrants were willing to integrate and contribute to the country, so it worked out well, but the migrants in the past few years were too many, do not want to integrate into the society, nor want to contribute to the country, so it makes huge problems on all levels.

- The skill levels of the immigrants;

From economic point of view it is crucial, because it might damage the economy if the skill levels of the migrants are very low, or if they have high skill levels, than it can be of great benefit for both sides.

- Immigrants' motivation for moving;

The motivation for moving is very important. While some immigrants move because they want a better life, want to prosper, integrate, there some that go into another country just to be leaching of a good social system (like it is the case with big portion of the new immigrants in Western Europe), or some that migrate temporary and plan to return to their homeland, so don't try to integrate into the society...
