Just some general observations from an old fart...
It's definitely not okay when Indians are brought in to take U.S.-based jobs as long as there are U.S. citizens capable of doing the same jobs at least as well. The H-1B program should not have anything to do with companies being allowed to pay less for talent. Regulating what our corporate overlords are allowed to do in the name of stockholder value isn't always a bad idea.
Most of the Indians who moved here won't assimilate much, and I don't think it's realistic to expect this process to happen quickly. It will take many years for most of those that choose to do so. If they're smart, they'll at least compromise and encourage their kids and grandkids to assimilate while still retaining the qualities of their culture/home life that contribute to their overall scholastic excellence.
Their kids and grandkids will be able to speak English clearly without an accent, and this should help reduce the barriers to assimilation. Personally, I work in the tech industry, and I'm always pleasantly surprised to meet an Indian whose accent doesn't make my eyes roll back in my head. I've noticed that as I get older, my tolerance for and ability to understand heavily accented English seems to be decreasing, and the Indian accent is one of the worst. Every time I hear "development" pronounced as "double-up-ment", a tiny part of my brain asks for permission to retire earlier than planned. Conversely, when I end up working with an Indian who speaks English clearly, it's such a pleasant surprise that I'm more engaged than usual in the conversation.
My FISD teacher wife thinks many "heritage citizens" in Frisco are simply failing their kids compared to the Indian parents. Generally speaking, it seems their priorities are out of whack. These parents value extracurricular activities and are highly involved in making sure their kids have everything they need to do their best when it comes to sports, etc., but they don't bring down the hammer like we did back in the day to ensure their kids are putting in the work to do their best scholastically. There are a lot of "cool moms" who no doubt love their kids, but good, well-rounded parenting has become less common. Sadly, our schools have lowered the bar due to lower expectations, which I consider ridiculous. Public education in Texas seems to be a slowly sinking ship, but what our government should do about it is another hot topic for debate.
