What precisely are "US values?" Do such values even exist? It's a free country, by the way. People are free to practice whatever and values and lifestyles they wish to (and THAT, in my opinion is the essence of what America is supposed to be), as long as they don't break the law. If you want everyone to speak English, then I suggest you campaign for legislation that would make English the official language of the United States.
There is a thing as American values, but aside from the fact I wouldn't want to type a long list..you can see it as somewhat anti-statist, individualistic, hard-working, religious, patriotic, and utilitarian. Now aside from that, there is this from Emerson about America: "..asylum of all nations, the energy of Irish, Germans, Swedes, Poles & cossacks, & all the European tribes-of the Africans, & of the Polynesians, will construct a new race...as vigorous as the new Europe which came out of the smelting pot of the Dark Ages.."
Or John Q. Adams: "They must cast
off the European skin, never to resume it. They must look forward to their posterity rather than backward to their ancestors."
But you could just as easily put in Tocqueville, couldn't you?:
"A society formed of all the nations of the world....people having different languages, beliefs, opinions: in a word, a society without roots, without memories, without prejudices, without routines, without common ideas, without a national character, yet a hundred times happier than our own."
"How does it happen that in the United States, where the inhabitants have only recently immigrated to the land which they now occupy, and brought neither customs nor traditions with them there; where they met one another for the first time with no previous acquaintance; where, in short, the instinctive love of country can scarcely exist; how does it happen that every one takes as zealous an interest in the affairs of his township, his country, and the whole state as if they were his own? It is because everyone in his sphere, takes an active part in the government of society."
