In 1907, Teddy Roosevelt said this quote about immigrants coming to the U.S., which still holds true more than 100 years later.
The letter was written by Roosevelt to the President of the American Defense Society. The full text, which slightly differs from the newspaper version, can be seen below.
“We should insist that if the immigrant who comes here does in good faith become an American and assimilates himself to us, he shall be treated on an exact equality with every one else, for it is an outrage to discriminate against any such man because of creed or birth-place or origin. But this is predicated upon the man’s becoming in very fact an American and nothing but an American. If he tries to keep segregated with men of his own origin and separated from the rest of America, then he isn’t doing his part as an American. There can be no divided allegiance here. We have room for but one language here, and that is the English language, for we intend to see that the crucible turns our people out as Americans, of American nationality, and not as dwellers in a polyglot boarding-house; and we have room for but one soul loyalty, and that is loyalty to the American people.”
