Abstract

The aim of this article is to offer solutions to the problem of undocumented immigrants in the United States, using the Spanish migration model as a possible solution. During the last decade Spain has been the European country that has received more migration flows due to his economic development. Spain has used the knowledge and experience of other European host societies to design a migration model, which avoids the social conflicts arising from the coexistence of large numbers of undocumented immigrants, and that could provide answers to the problems faced by the US system.
