How much does the illegal immigration really cost Americans?

Here are some interesting statistics on how much the average illegal immigrant costs the American people.  This is pretty important considering there is a immigration bill about to be passed that could legalize 12 million illegal immigrants.  Here are the interesting fact that I found on this website:
1. $11 Billion to $22 billion is spent on welfare to illegal aliens each year.
