I've taken the figures from the above table at cis.org and graphed them.
Note the sharp increase in immigration from Mexico and how that differs from all other regions' increase. Note also the sharp decline in immigration from Europe while all other regions have increased.
Roughly 63% of illegals are Mexican.
As of March 2010, 11.2 million unauthorized immigrants were living in the United StatesOur immigration policy must serve our needs, our ability to absorb, and immigrants' ability to assimilate. Creating large sub-societies serves no good purpose.http://www.pewhispanic.org/2011/02/01/unauthorized-immigrant-population-brnational-and-state-trends-2010/
Then see Figure 2 at http://www.pewhispanic.org/2011/02/01/ii-current-estimates-and-trends/
Do the math.
Our security can not be conditioned upon the demands of unassimilated immigrants or illegally present foreigners.
