What are "border zones"?

"Border zones" refer specifically to areas within 100 miles of the U.S. borders where Border Patrol has heightened enforcement authority. This designation allows for increased vigilance and enforcement against illegal immigration and border-related activities. The rationale behind this allowance is to enhance border security, addressing concerns regarding unauthorized crossings and smuggling operations.

This concept is significant as it underscores the operating jurisdiction of border authorities, enabling them to take proactive measures to manage and control immigration within a critical range of the border. In these zones, customs and immigration regulations can be enforced more stringently, which can include increased checkpoints and surveillance.

Other options describe different concepts unrelated to the operational framework of border enforcement. For instance, the processing of citizenship applications pertains to immigration procedures rather than geographical enforcement areas. Similarly, regions marked by cities do not inherently define areas of heightened security or authority. Lastly, locations designated for legal immigration pathways involve structured processes and resources for lawful entry, which is distinct from the enforcement-aimed nature of border zones. Understanding this distinction highlights why the definition of "border zones" is rooted in heightened enforcement authority.
