"Migrant shelters along the Mexican border are filled not with
newcomers looking for a better life, but with seasoned crossers: older
men and women, often deportees, braving ever-greater risks to get back
to their families in the United States — the country they consider home.
They present an enormous challenge to American policy makers, because
they continue to head north despite obstacles more severe than at any
time in recent history."
