What was the usual settlement pattern of immigrants once they arrived in America?

The usual settlement pattern of immigrants, once they arrived in America, was immigrants living close to people who had similar cultures, ethnicities, and religions. Immigrants arrived in the U. S in late 1800s from Southern and Eastern Europe from Italy, Poland, Greece, Russia, and Africa. A majority comprised of Roman Catholics from Italy, Jews from Russia who were fleeing religious persecutions. These groups usually faced discrimination thus clustered according to their cultures, ethnicities, and religions.
