I understand legal immigration very well.<quoted text>
There is no such thing as "the back of the line".
What part of LEGAL immigration DO YOU NOT understand?
Opponents of illegal immigration are fond of telling foreigners to get in line before coming to the USA but what does that line really look like and how many years or decades does it take to get through. Below is a PDF diagram that shows you the complexities of doing it the legal way. It may also help you understand why many foreigners simply say to hell with it and enter illegally.
Apparently your aren't cognizant with "back of the line" being a phrase meaning "do it legally or don't do it at all."
If everyone that was frustrated with laws broke them chaos and anarchy would prevail. Pretty much like Mexico.
