According to the Washington Examiner, half of residents of big US cities don’t speak English at home. The implication, of course, is that the overwhelming groups of immigrating people, legal and otherwise, consist of Hispanic speaking families and their young children.
Coincidentally, my memories go back almost a century to childhood days in the 1920s big city of Philadelphia. Up to age six, I rarely heard adults speak English in my house and nearby neighborhood. Both Mom and Dad had come to America as pre-teen kids. When older relatives were visiting, no one spoke English. It was German, Yiddish, Russian and Polish.
In nearby South Philly homes, it was Italian. As it happened then, now we must allow time for school-age immigrants to integrate into our culture and language. Remember, when the Spanish conquistadors came ashore in Mexico and the Pilgrims landed in Massachusetts, there was a similar problem. The indigenous native Americans must have been concerned about the foreign ways the immigrants talked. http://www.washingtonexaminer.com/washington-secrets/nearly-half-in-top-5-u-s-cities-dont-speak-english-at-home-record-67-million
