SAN DIEGO (AP) — The U.S. Border Patrol is unveiling its first national strategy in eight years, a period in which the number of agents more than doubled and apprehensions of people entering illegally from Mexico dropped to a 40-year low.

Chief Mike Fisher is expected to outline the plan Tuesday in Washington. The new approach relies on buzzwords like "risk-based" and "intelligence-driven" to describe a more nuanced, targeted response to constantly evolving threats.

The Border Patrol has relied on a strategy to blanket heavily trafficked corridors for illegal immigrants with agents. The idea was to push migrants to more remote areas where they would presumably be easier to capture and discouraged from trying again.
