Four years ago, Maria Cecilia Osorio followed her husband north from Mexico with her two children, now eight and twelve.
Her husband traveled to the United States in search of work and Maria followed.
But upon arriving in Nogales, Arizona, a small border town with a population of 20,000, they separated.
Her husband was abusive.
Maria took her children and left her husband.
They sought refuge in a family shelter.
Finding work was difficult for Maria, now a single mother.
