Undocumented and unaccompanied youth have "varied and complex reasons" for migrating in droves from El Salvador, Honduras, Guatemala and other nations. They move across the southern border with the assistance of coyotes and smugglers; these children hope to evade threats of rape and death that they routinely subjected to in their homeland. They reach the U.S., but many are caught; and those who are detained must submit to immigration proceedings without legal representation or guidance.
