How do the U.S. and Mexico harm eachother?

Well, i think that mexico harms us, by bringing in illegal immigrants, and alot of times, that causes alot of times. I also think that mexico harms us, by bringing in the drugs from the illgeal immigrants.

i think that the u.s. harms mexico, by alot of times, the illlegal immigrants might try t ocross the border, they might die, and when we cross the border, alot of times we do not thik about it, we think and that we do not listen to the rules or laws there

I found this website very helpful because it says what an illegal immigrant can and cant do. For example, it says that an illegal immagrant can bupy a car, can buy car insurance, but cannot get a drivers license.
