robertsnj You have to remember that anyone from India who immigrated to the USA only got there because they had money, not because they were poor people in India.
Because cultural language differences are a big deal in India to the point where a rich Indian won't even speak Hindi to a lower class designated person in India, it is highly unlikely that any well-educated East Asian living in the USA who of course speaks English would embrace the concept of actually speaking Hindi among their more affluent Indian friends and acquaintances in the USA.
The Indian culture is a culture unto itself and East Asians have no desire to try and pretend that American culture can be integrated into what they've otherwise known all their lives from their own cultural upbringing, meaning that the two cultures are like oil and water. If Hindi is embraced as a second language in America, who that language would be serving are what East Asians refer to as the lower class of East Asian culture who do not contribute anything of significance to the society they live in.
