The area, known as the Rio Grande Valley Border Patrol Sector, accounted for 46 % of all apprehensions in 2016. From 1998 to 2012, most apprehensions occurred near Tucson, Arizona. Much of Arizona’s southern border is now fenced off. That has significantly reduced crossing there but led to increased crossings further east, in Texas

An intelligence report compiled by the U.S. Customs and Border Protection agency reveals that large numbers of immigrants originating beyond Latin America are illegally crossing the southern U.S. border.

The report, which was leaked to Breitbart Texas by a source within the CBP who spoke on the condition of anonymity, records the numbers of individuals being caught or turning themselves in to Border Patrol agents from 2010 through July 2014.

The illegal immigrants originated from more than 75 different countries. Among the overseas destinations listed in the report are Syria and Albania, from which smugglers send immigrants first to Central America and then northward across the U.S. border.
