Which area is significant for illegal crossings due to its proximity to Mexico?

The Rio Grande Valley Sector is particularly significant for illegal crossings due to its geographical advantages and proximity to Mexico. This area along the Rio Grande River serves as a natural boundary between the United States and Mexico, creating multiple access points that can be exploited for unauthorized crossings. The river itself has sections where individuals can wade across, and the surrounding terrain can provide cover for those attempting to illegally enter the U.S.

Additionally, this sector has a high population density and numerous urban areas that facilitate the movement and transportation of individuals once they cross the border. Local conditions, such as climate and vegetation, also contribute to the increased instances of illegal crossings. As a result, border patrol efforts in this area are critically focused on managing and monitoring the situation, making it one of the most notable sectors in discussions of border security and immigration issues.
