"In the United States, we speak English, please."
Here's a breakdown of the errors:
* "ingles" should be "inglés": The correct spelling of "English" in Spanish is "inglés".
* "por favor" is misplaced: "Por favor" means "please" and should be placed at the end of the sentence for better flow.
* "hablamos" is a bit awkward: While technically correct, "hablamos" (we speak) sounds a bit formal. "Se habla" (it is spoken) might be a better choice for this context.
Here are some more natural ways to say it in Spanish:
* "En los Estados Unidos, se habla inglés." (In the United States, English is spoken.)
* "En Estados Unidos, hablamos inglés." (In the United States, we speak English.)
* "En los Estados Unidos, el idioma oficial es el inglés." (In the United States, the official language is English.)
