But a good estimate can be made by looking at the number of different languages spoken in the USA.
Total number of languages spoken in the USA = 311.
Number of languages that are indigenous to the USA = 162.
Number of immigrant languages in the USA = 149 (this includes English).

But a spoken language is not synonym of official language. Russia is federative state with the republics of many ethnic groups, there is more 25 local official languages, besides Russian.

I know that Putin speak some Swedish.
Does that qualify to an official language?
I mean Putin is the president of Russia and have the highest official position:)

And Sergey Ivanov who was the Chief of Staff of the Presidential Executive Office.
Ivanov is fluent in English and Swedish as well as speaking Norwegian, and some French.

There is a list of the top 10 non-English languages in Texas.

Again, the USA does NOT have an official language. English is only the most common language spoken in the USA... Nothing more.

Even the Internal Revenue Service (our Federal US Government's tax collection agency) supports a number of languages....

Including THIS one...

Don't blame me, I voted for Johnson(L) in 2016.

MK. Here in Europe an official language means that governments and institutions like school and healthcare have to communicate in those languages.
Now for spoken languages.
Here when voting there are instructions in 40 languages:)

But our tax collection agency only use two! Hmmm...

Oh. I forgot.
https://en.wikipedia.org/wiki/Swedish_Sign_Language

]Swedish Sign Language (Svenskt teckenspråk or STS) is the sign language used in Sweden. It is recognized by the Swedish government as the country's official sign language, and hearing parents of deaf children are required to learn it.[4] There are less than 10,000 speakers, making the language endangered.[5]

Yes, that is pretty much the definition of official language here. Government HAS to communicate in that/those languages.

But, as I have said, the USA (US Federal Government) does not have one. Some States DO have one or more, however.

But a ballot printed in 40 languages? Urrgh... Is that a nationwide requirement for the same list of 40 languages?

Here in Texas, we just (usually) print ballots in the top 3 languages... English, Spanish, and Vietnamese. Though I suspect that in some places in Texas, the list of languages might be different.

Here is a sample ballot for the May 6, 2017 election for City of Fort Worth, Tarrant County, Texas (Fort Worth City Council place 9).

Igor, this statement of yours makes no sense. An official language must be official de jure (by law). A language that is most popular is just that... most popular. That does not make it an official language.

Besides, English is losing ground to other languages. About 1/3 of Texans now speak a language other than English at home.

And the U.S. states is not ethnic republics. So it's like comparing apples and oranges, no sense.

No ethnic governments within the USA?? Try telling the Cherokee Nation (and many others) that...

The Cherokee Nation is the federally-recognized government of the Cherokee people and as such has sovereign status granted by treaty and law. Its capitol is the W.W. Keeler Complex near Tahlequah, Oklahoma the capital of the Cherokee Nation. Cherokee Nation has operated under a constitutional form of government since 1827. Today there are more than 320,000 registered Cherokee citizens, making us the largest Native American tribe in the United States.

The modern Constitution of the Cherokee Nation was approved by the Commissioner of Indian Affairs on Sept. 5, 1975, and ratified by the Cherokee people on June 26, 1976. A Constitutional Committee convened in 1999 to create a new Constitution. In 2003 the Cherokee people voted overwhelmingly to accept it. The new Constitution was enacted in 2006 and calls for a tri-partite government consisting of Executive, Legislative and Judicial branches.

MISSION:

"The Cherokee Nation is committed to protecting our inherent sovereignty, preserving and promoting Cherokee culture, language and values and improving the quality of life for the next seven generations of Cherokee citizens."

http://www.cherokee.org/Our-Government

Note: as of 2015, there are 567 federally recognized Tribes in the USA.

What? Don't you speek English over there?
Or perhaps do you mean the difference between US English and UK English?
And what is a popular language?
Here the most "local" popular language is "Ekensnack".
Try to translate this.
"Hojja ner till tjorren och tjacka taggar till mig"
"Rätt just asså".
"Ã… Fan".

LOL, yes. That reminds me of an incident I had about 45 years ago.I was playing rugby with a men's club in Seattle. The roster was about half American and half British expats. A team mate kept yelling at me to do something during play and I couldn't understand a word he was saying. After the game while having a beer with the captain, an Englishman I said Dennis I couldn't understand what Ian was trying to say. He responded not to pay him any mind, Ian is a Welshman and no one can understand what they say.

I know exactly what you mean.
When I joined the Army, in the early 60's, I'm certain I was put into that barrack room so that there was an interpreter so that there were not to many misunderstandings.
the inhabitants of that barrack room were,
a Scotsman from a hamlet between Inverness and John o'Groats,
a Glaswegian from the Gorbals,
a Geordie from about 5 miles outside Newcastle,
two Liverpudlians, but culturally completely different. Good friends there but I suspect back home they wouldn't have even acknowledged each other if they met unexpectedly,
a Welshman who's family spoke Welsh at home, so English was a 2nd language,
a Cornishman, they're ancient Britons so not really English,
two Londoners, a Cockney barrow boy, the other was from Twickenam (not a rugby player),
And me son of an ex-pat, who until a year before, had lived in the diplomatic quarter and who's only radio station was the World Service.

I think in was about 10 weeks before they could all understand each other.

Oh my God, Liverpudlians.
My sister and my nephew Matthew are Liverpudlians.
Please have Mercey.

Igor, this statement of yours makes no sense. An official language must be official de jure (by law). A language that is most popular is just that... most popular. That does not make it an official language.

An official language of state de-facto is the language of Constitution, code of laws and judges, oath of allegiance. Therefore, de-facto English language is the official language in the USA, still.

Besides, English is losing ground to other languages. About 1/3 of Texans now speak a language other than English at home.

Besides, I know that situation. Forecasts that this tendency will lead USA to a collapse, it has appeared many years ago already. And recently, one my friend of Kazakh ethnicity, he had moments with big troubles when he traveled in Texas because some local people tried to speak Spanish with him and they were very angry - "Why you doesn't want to speak your native language?" Some of Kazakhs looks like Mexicans.

No ethnic governments within the USA?? Try telling the Cherokee Nation (and many others) that...

The local constitution, code of laws and courts/judges in the local languages? Well, one little exception to the rules - this is only one little exception, not 25. And no one of 50 states of United States is ethnic state with prevailing of non-English speaking population, for the present.

P.S. All it is offtopic and not interesting for me.

We all know that most US common people are ignorant.

I don't think you understand this one. Cherokee Nation, while it is within the State of Oklahoma, isn't really part of it. The relationship between Cherokee Nation and the US Federal Government is fixed by treaty between the two nations.

Yes, the Cherokee Nation is 'one exception'... Also, remember that there are 566 OTHER tribes.

Native American tribes in the USA have 'tribal sovereignty'.

Federally recognized tribes are considered domestic dependent nations. Tribal sovereignty refers to tribes' right to govern themselves, define their own membership, manage tribal property, and regulate tribal business and domestic relations; it further recognizes the existence of a government-to-government relationship between such tribes and the federal government.

Tribal Sovereignty was established in a series of 3 US Supreme Court Cases:

Johnson v. M'Intosh (1823), Cherokee Nation v. Georgia (1832), and Worcester v. Georgia (1832)

In opinions given by Chief Justice John Marshall.

It has since been reaffirmed in a number of cases, especially this one:

In Bryan v. Itasca County (1976), the Supreme Court ruled unanimously (9 to 0) (in an opinion given by Justice Brennan) that State tax and regulatory laws do not apply to Native Americans living on reservations (tribal land).

In the USA, Native American Tribes have a level of Sovereignty at a level between the States, and the US Federal Government.

That may be true but when you live next to one you would realize they are a very unique subset and not part of a homogeneous political body.

Igor probably meant indigenous nations.
Yes there are many in the US.
But they don't have any political power like indigenous nations in Europe and Asia has.
