HBO is showing a documentry titled Which Way Home that tracks central american immigrants, children, trying to make it to the United States. It is sobering. I recommend it.
http://www.hbo.com/docs/docuseries/whichwayhome/index.html"Each year, thousands of Latin American migrants travel hundreds of miles to the United States, with many making their way on the tops of freight trains. Roughly five percent of those traveling alone are children. As the United States continues to debate immigration reform, the documentary WHICH WAY HOME looks the issue through the eyes of children who face the harrowing journey with enormous courage and resourcefulness.
An official selection at the 2009 Tribeca Film Festival and the 2009 Los Angeles Film Festival, WHICH WAY HOME follows several unaccompanied child migrants as they journey through Mexico en route to the U.S. on a freight train called "The Beast." Putting a human face on the immigration issue, director Rebecca Cammisa (the CINEMAX documentary "Sister Helen") reveals some of the reasons kids resort to drastic and dangerous measures, among them: bringing an end to long-term separation from their parents; escaping life on the streets; lack of jobs or educational opportunities at home; and hopes of a better life north of the border."
