Slideshow: Border Bus

On both sides of the border, there are calls to end the U.S. Border Patrol's Alien Transfer and Exit Program. But Border Patrol officials say their plan to break the connection between smugglers and immigrants is working.

Two months ago, U.S. Border Patrol started bringing two busloads of undocumented immigrants each day to the small, isolated Texas border town of Presidio. The immigrants, transported here from Arizona, are repatriated just across the international bridge in the poverty stricken city of Ojinaga. The program has caused an uproar in this tight-knit border community and has officials on both sides of the border calling for an end to the Border Patrol's Alien Transfer and Exit Program. But Border Patrol officials say their plan to break the connection between smugglers and immigrants in the Arizona area is working, and they're not likely to stop the buses anytime soon.
