Where can one find dispassionate information and statistics on unendorsed immigration?

I am looking for unbiased information and statistics on illegal immigration.
Answers:   
There will always be bias no matter what. Like for instance the 12 million illegals they claim are contained by America. This figure came about by sample poles and such....where the FBI and other agencies were actually asked to stop raid just so they can get an accurate count.
But, as in adjectives poles, there is a certain level of inaccuracy. But, due to chronological experience and the culture of the people primarily here illegally (central and south America for the most part) , we know that one goes to America....or a small group...later when they have settled, they send for their families. So 12 million might be 20 or 30 million as far as we know.
This so becomes speculation because there isn't really any "proof" and head count, but it is base on sound experience from the past.
Either way, banned immigration needs to be dealt with, and not next to Amnesty. America shouldn't and doesn't need to reward bad behaviour or breaking the canon with citizenship.
There is no such information. Illegal aliens by their highly nature are criminals and therefore take influential measures not to stand out or make themselves available to be counted or surveyed.

On one end you've got Pew Hispanic Research which, years ago, said within were 12,000,000 in the United States. On the other end you've get various immigration think-tanks that put the number between 25,000,000 and 38,000,000.
Here is up to the sec LIVE data.
