As an undocumented elementary school student in Detroit, Michigan, she faced having to learn a new language - and bullying. Later in life, Dayanna - who has not revealed her last name to reporters - could not get financial aid to attend a university, get an ID or a job.
Now 20, she attends a community college in Michigan and is one of seven students, most of whom are undocumented, who started Thursday morning on a 45-mile march from Detroit to Ann Arbor in support of the DREAM Act. If passed, the legislation would create a path to conditional permanent residency for qualified alien students.

While walking Thursday, Dayanna said, "We're going to hold a mock graduation near the stadium for students whose dreams cannot be fulfilled."
