US immigration is an absolute nightmare especially for Indians.
In Europe its simple. Job offer above minimum salary? Apply and get a blue card yourself. Has been in the country for over 5 years and speak the language? You get citizenship.
In the US its nearly impossible to get a Green Card. Forget how difficult it is to get an H1B visa in the first place because of the lottery system.
India has a brain drain problem. The most profitable career in India is to leave India and become an immigrant.
The US is not responsible for that problem and never will be. And even if the US fixed its immigration inconveniences, the problem in India would remain.
India has other problems as well. For software engineers, the number one threat of hiring from India are the corporate cultures at Infosys, TCS and similar companies. I do not want to work with the alumni of those work cultures. It's radioactive-level toxicity.
The US should absolutely make it easier for brilliant people to immigrate. A very high bar for immigration + a simpler process for such people is a net benefit. The current H1B process is broken and exploited. Some Indian kid graduating from Berkeley with a perfect GPA shouldn't have to rely on a lottery system.
The bar for H-1B is bachelor's degree from almost any institution. What you describe (top student from top school) does not represent the elegibility criteria for H-1B, or the profile of most people being granted that visa type.
H visa is not for world class top talent, that is the E visa.
Friends of mine pursuing Swiss citizenship had a much longer road than what you describe above. I know them to be pretty fastidious when it comes to paperwork exercises and they did not have citizenship after 10 years, though they indicated they were on a path towards it.
That's because Switzerland needs 10 years in the country for citizenship. Spain too. Switzerland also has a lot of extra steps in their citizenship process. It is vastly easier and simpler in say the Netherlands.
In Switzerland you have to apply for citizenship to the local government, and each one of them is xenophobic to various degrees. There are some famous cases where citizenship was denied because the person had a few speeding tickets, or thought that loud cowbells should be forbidden because they torture cows.
In Europe its simple. Job offer above minimum salary? Apply and get a blue card yourself. Has been in the country for over 5 years and speak the language? You get citizenship.
