Yes, but on the other hand, there is a significant portion of legal immigrants, unfortunately, who worked somehow to get their remaining relatives into the country illegally and also broke the law themselves in the process.

It is like "once you safely reach Tucson, Jorge, give Uncle Eduardo up in San Bernardino a call and he will come down to pick you up". There is no denying this. If they move all together back to where they came from, legal, naturalized citizen or not legal alike, if it is a joint "illegal harboring" racket, underground railway enterprise nationwide, why then that will be just fine with me.

You have hit on it exactly!
Very often the legals are mixed in with the illegal aliens
They live in the same house
They are members of the same family
Often you can have where dad is legal but mom and the two children are illegal. 
Or you have two illegal aliens with 3 anchor babies who of course are legal

Oft times legal aliens are the major employers of illegal aliens

What I really despise is when illegal aliens complain about not having "papers" That's where you get that "undocumented " bs.
