Which section permits entry onto private lands within 25 miles of the border for specific searches?

The correct response pertains to INA § 287(a)(3), which specifically allows immigration officers to enter private lands within 25 miles of the U.S. border without a warrant for the purpose of conducting specific searches related to immigration enforcement. This provision reflects the need for agencies to have the ability to quickly respond to potential immigration violations in border areas, which are often characterized by a higher incidence of unauthorized crossings.

This section establishes a legal basis for the enforcement actions taken by immigration authorities, acknowledging the unique context of border enforcement and the challenges posed by maintaining immigration laws at such proximity to international boundaries. The ability to conduct searches without a warrant in these designated areas is aimed at improving the efficiency of border enforcement efforts, ensuring that officers can act rapidly in areas where the potential for illegal activity may be heightened.

In contrast, the other provisions listed either address different aspects of immigration law enforcement or cover different contexts, such as entry alerts or procedural requirements that do not specifically grant the same level of latitude regarding entry onto private lands near the border.
