"The Secure Border Initiative (SBI) is a comprehensive multi-year plan to secure America's borders and reduce illegal migration. Homeland Security Secretary Michael Chertoff has announced an overall vision for the SBI which includes:  More agents to patrol our borders, secure our ports of entry and enforce immigration laws.  Expanded detention and removal capabilities to eliminate "catch and release" once and for all.  A comprehensive and systemic upgrading of the technology used in controlling the border, including increased manned aerial assets, expanded use of UAVs, and next-generation detection technology.  Increased investment in infrastructure improvements at the border - providing additional physical security to sharply reduce illegal border crossings.  Greatly increased interior enforcement of our immigration laws - including more robust worksite enforcement."
