It sounds like you're in one of the towns in NJ. There are towns here where you don't know what country you're in anymore. We've had so much immigration here, legal and illegal, it has ruined much of the state. They do not assimilate, they set up their own communities.

Where I live, which is more rural, there is not as much. There is nothing here for them. No buses, limited train access and its quite expensive. The few that I've seen are mostly landscape workers. This has remained mostly a cow town. There are a lot of small family owned farms.
