"A recent Pew Hispanic survey found that more than 70 percent of illegal immigrants from Mexico are interested in a guest-worker program and then returning home"

This quote by John Shadegg is referring to a study conducted by the Pew Hispanic Center which discovered that a majority of unlawful immigrants from Mexico are interested in a guest-worker program. This program would enable them to work in the United States for a certain time period and after that return home. This recommends that most of unlawful immigrants from Mexico are not looking to remain in the United States completely, however rather to work here momentarily and after that return house. This might be beneficial for both the immigrants and the United States, as it would supply a legal method for immigrants to work in the United States and add to the economy, while also enabling them to return house and reunite with their families.
