240,000 is way more than your initial 40,000, yet you still say it's a small fraction.
So many articles say differently. I guess they could be all wrong. https://www.forbes.com/sites/quora/2016/04/14/how-the-salari...
I have plenty of friends who work for Infosys and TCS. None of my friends even applied for a green card and they all went back to India after a couple of years here at the most. Many postings in the US at these companies last only 9-12 months. And neither TCS nor Infosys have any interest whatsoever in helping people immigrate to the US. (You need an employer to file a PERM application if you want a green card. A green card is required if you want to stay here more than 6 years.) That is the exact opposite of what they want to do.
The article you've mentioned says nothing about H1Bs. Outsourcing is not going to go away even if you eliminate H1Bs. And yes, all these articles making noise about this epidemic of H1Bs are in fact wrong. They're written by a bunch of poorly-informed Americans who wouldn't know the difference between an I-140 and an I-20. And their goal is to just generate clickbait to cater to nativist sentiment in the US. There's a lot of conservatives who emphatically don't want more Indians in this country. But they know they'll never win if they argue that they don't want Google and Microsoft employees here. So instead they've come up with this nonsense about Infosys and TCS stealing American jobs.
