What is a "border incursion"?

A "border incursion" refers to an unauthorized entry into the U.S. This term typically describes situations where individuals or groups cross the border without permission, violating immigration laws and protocols. Understanding this concept is essential as it highlights the challenges faced by border patrol operations regarding illegal immigration, smuggling activities, and the enforcement of national security measures.

The other choices do not accurately define "border incursion." Strategies for international cooperation focus on collaboration between countries rather than unauthorized crossings, while authorized entries imply compliance with immigration laws, which contradicts the idea of an incursion. Border surveillance is a method used to monitor activities at the border but does not directly relate to the concept of unauthorized entry. Therefore, recognizing "border incursion" as an unauthorized entry provides a clear understanding of the term's implications in border security operations.
