Immigrants integration

I think inmigrantes are not completely integrated. Most of them come from Africa because of its proximity to our country from Latin America because of the similar culture and the same language and from Western Europe because of Spain’s south climate. They come because they want to escape of poverty, war or political instability.
The people of the countries who mainly come to Spain are from: Romania, Morocco, United Kingdom, Italy and Ecuador.
Inmigrants are very accepted because they are isolated from the society, and now when they come to Spain they are not used to Spain's culture and also they aren’t used to study so they can’t find a job easily.
