People often forget how the entire ecosystem is structured, when the Trump administration wanted to send back people who were on Green card wait, a statistic was published in the local newspapers here in India. Apparently there were a good 6+ lacs H1-Bs residing in US currently. Add L1 and F1 categories, to it, then add green card holders and you could be staring at 10+ lacs Indians/Indian orgin people in the US already.

This is already a lot of people. In some way there are already enough Indians working in the US.

This number already rivals the entire head count of several Indian IT firms added together.
