The river Rio Grande, which flows from the southwest of the United States into parts of northern Mexico, forms part of the US southern border with Mexico. The region, which is relatively easy to cross, is known to be a hotbed for illegal-immigrant apprehensions, with 36,872 migrants apprehended in July, according to CBP data.
