I don’t care what an article says or doesn’t say, illegal Mexican immigration has increased here in Maryland. In fact, to the visible eye, it has increased quite dramatically. Just a thought
The Pew study depends upon self identified illegal immigrants, and focuses on border states, and this study supposedly concentrates on those from Mexico alone.
In Maryland, there's a huge population of illegal Brazilians, as well as those smuggled from Guatemala. Both of those aren't counted on the Pew study.
Still looking at an overall illegal population of 20 million people... That's a job for every person who is looking, or has stopped looking. Illegal immigration doesn't hurt anyone, of course... Or so we're lied to about.
