And it's true by and large - most Indians who immigrated to the US after 2010 will never become citizens in their lifetime because of the green card backlog.
Every person who was born in India and is the US on any visa except an O-1 knows their time in the US will eventually end because of the GC backlog. And the other options (eg. Canada, UK, Germany) aren't as entice because of the horrid job market.
Also, any legitimate research should mention conflict of interest by the researching organization. In this case, it's a staffing company, so there's reason to believe that there might be conflicts of interest.
But GCs have a country cap, and the current backlog for those born in India is in the decades range.
EVERY Indian, Chinese, Mexican, and Filipino national knows this as those are the 4 nations with country caps today.
Chinese nationals have a similar backlog as Indians hence why the reverse brain drain began in the late 2000s and early 2010s. White-Collar Mexicans tend to use the TN visa to maintain de facto permanent residency. For Pinoys I actually have no idea.
While a green card makes it easier to get a US citizenship, it is not a requirement for it.
Almost all Indian nationals who immigrated to the US since 2010 were born in India and as a result of the country of birth backlog will never get American permanent residency or citizenship in their lifetime.
The only ways to become an American without having a green card is being born in America or being born to an American citizen.
