The illegals from the Far East as I understand it come in on a legal visa but don’t
leave. And they now represent a large number each year and some say possibly a
larger number than the southern border illegals
The first phase (of Trump’s Wall Plan) would be the smallest, targeting sections covering 26 miles (42 km) near San Diego, California; El Paso, Texas; and in Texas’s Rio Grande Valley.
The second phase of construction proposed in the report would cover 151 miles (242 km) of border in and around the Rio Grande Valley; Laredo, Texas; Tucson, Arizona; El Paso, Texas and Big Bend, Texas.
The third phase would cover an unspecified 1,080 miles (1,728 km), essentially sealing off the entire U.S.-Mexico border.
My estimate is that $1.6 Billion would approximately cover the first two phases, at around $9 million per mile.
Visa overstays are a huge problem - almost anyone can get a tourist visa.
There is basically no followup for overstays, unless they are arrested for something else.
I just saw this report from today (http://www.theolympian.com/news/business/article179842706.html):
“Trump has asked Congress for $1.6 billion to replace 14 miles of wall (22.4 kilometers) in San Diego and build 60 miles (96 kilometers) in Texas’ Rio Grande Valley, the busiest corridor for illegal crossings.”
That would be 74 miles at around $21 Billion per mile - very robust infrastructure and/or very high acquisition costs.
Manual profiling should hinge on appearance and accent. After that, it's "your papers please".
Sorry, but we have a serious crisis.
