There is a big difference between Latinos and most other ethnic nationalities in the United States. The other people (Germans, Russians, Greeks, Irish, Italians, Chinese, etc. etc.) came to the United States. In the case of Latinos, the United States came to them. First in Louisiana which was Spanish territory for many years before Spain was forced to give it back to France. The name Louisiana is really a Spanish name. The French name is Louisiane. Then in Florida. Then in a big way in northern Mexico. Finally in Puerto Rico. So Spanish is just as much a language of the United States as English is. They are both languages of the conquerors and colonists, and neither language is indigenous. But if you look at the history you can see that Spanish was spoken here before English because Saint Augustine was settled before Jamestown.
