Prairieland's proximity to the Dallas area makes it more accessible for lawyers representing clients detained there, the Chavez & Valko site states. The other three facilities in the operations area of ICE's Dallas field office are in Anson, Eden and Haskill, at least a 3-hour drive west of the Metroplex.
