As a conclusion, we can say that Mexican immigration bring a new culture but also drogs in USA and violence in Mexico .I fence were build to prevent this but is not very effective .In my opinion, immigration in the USA can be helpful for the American economy because a part of the American economy seems to be based on unskilled workforce. Although some Mexicans enter the USA illegaly, they are ready to face difficult working conditions .
