USA Immigration Studies & The Legal Status Question

As an old fictional hoboclown detective, I've learned that one key to getting informed is to ask questions and obtain information.I've gotten a lotta sources of information by picking up dirty little pennies and discarded old papers.Sometimes, you just idle along ignorantly and at other times you latch onto gems of facts.Facts are only tools( in and of themselves)of further discovery and greater understanding. Discovery and understanding gives an ignorant old clown like me, more latitude in drawing conclusions and at least minimal insight. I just used some big words to generate some small ideas. Sometimes, it's the other way around,like electricity; using a lotta tiny things to generate a lotta power! If you want some powerful thoughts on the issue of 'legal path to immigration', look at the information pulled together on US Immigration by the Rice University authors in the following link, http://kinder.rice.edu/uploadedFiles/Kinder_Institute_for_Urban_Research/Publications/White_Papers/Immigration%20White%20Paper.pdf
