It's worse than that. As Tancredo pointed out last week, close to 30 million illegals will become legalized, thereby becoming anchors for their families.
If only 2 more family members per new citizen are brought in, that's an additional 60 million just like that.
How will we ever assimilate close to 100 million new people?
Don't worry, there only 100 million people left in Mexico and only 60% of them want to come to the USA.
