So far, nearly 500,000 people have crossed the southern border this year; it’s presenting problems for more than just law enforcement.

Volunteer groups taking care of migrants say they, too, are overwhelmed by the numbers they're trying to serve.

Shelter directors are searching for any help they can get.
