and there were more apprehensions of non-Mexicans than Mexicans at U.S. borders in fiscal year 2017 for the third time on record (the first was in fiscal 2014).
In fiscal 2017, the Border Patrol made 130,454 apprehensions of Mexicans, a sharp drop from a peak of 1.6 million apprehensions in 2000. The decline in apprehensions reflects the decrease in the number of unauthorized Mexican immigrants coming to the U.S.
There were 180,077 non-Mexicans apprehended.
So at 300,000 caught that means 75,000 got thru, they have less than a $5 billion impact on gov't costs.
