I don't know much about illegal immigration in other places, but while mexicans might be a problem over there, brazillians are a huge problem here. I live in a large town (~60,000 people) and there are supposedly an estimated 5,000-10,000 illegal immigrants living here, the vast majority from brazil. That's a lot of freakin boarder hoppers for one town.
And trying my best not to be racist, I have to say that they can at the very least be a nuisence. A stack of illegals live across the street from me, and they love to be rediculously loud in the middle of the night, but aren't terrible compared to a lot of them. Last time brazil won the soccer world cup it was impossible to drive through downtown. I can understand being happy and celebrating, but this isn't fucking rio de janeiro, celebrate if you want but keep that shit in your homes. When you start affecting the rest of the town you're going to far.
