I am Indian origin worker. It's very true they are very corrupt in mind and discriminatory. These things are rampant in the US. In 2018, The states of Andhra Pradesh(Hyderabad city is in this state. Now this state is split into two states viz. Andhra Pradesh and Telangana in 2014) and Tamilnadu(Madras/Chennai is the leading city in this state) was rated #1 and #2 in corruption. They wouldn't let any other Indian their IT team. See the 2011(tri-valley university scam) where Almost 90% students was from Andhra Pradesh and had the same address of an apartment for fake college admission just to get OPT VISA.
This is the survey on Indian IT discrimination. This mini-site is broken down into just a few tabs.
