I won't say that facts & figures presented by the Center for Immigration Studies may be biased, but I will say they are so full of confusing jargon, acronyms and explanations of technicalities that it's impossible to make any sense of it.
It may be confusing, but according to ICE's
own numbers, the bulletted "Key Findings" are spot on. The removals at the border are up, but interior removals are down, and the vast majority of removals are due to criminal convictions, not due to simply being here illegally.
ICE and CBP's stated primary mission is the identification and apprehension of, and the detention and removal of, criminal aliens and other removable individuals located in the United States. Based on the removals, "other removable individual" no longer means "illegal" like it used to. Apparently it doesn't mean much at all. Unless you have been convicted of a crime before you got here, or unless you are convicted of a felony after you got here, you can stay here, legal or not, as long as you want.
The ICE web page states plainly, "[in 2012] ICE focused interior enforcement operations on convicted criminals with an emphasis on those convicted of the most serious crimes." So unless you have committed either a felony or three (count' em three) misdemeanors
each with a punishment of less than one year, they don't care.
Not a single country on the planet has the kind of immigration incompetence we have. It's downright embarrassing as a US citizen to know that we can't even control our own land borders, despite 7,476 miles of it being land border and the oceans being the other 95,471 miles of the border.
