What is the real number for illegal immigrants in America? I think its at least 80 million.

I live in CT and noticed an explosion of Indians in our state. Entire apartment complexes have been taken over by Indians. I remember when I was a kid and going past some areas the apartments were mostly younger people renting until they found their first house. Now, it's all jeets. They are everywhere, Costco, Sam's Club, outdoor restaurants, etc.
