Because the queue for a US residence permit is currently ~100 years for Indian citizens, and there's a very low acceptance rate for work visas for Indian citizens. It's far easier for employees from other nations to change jobs in the US.

It’s very relevant because he’s dependent on visa sponsorship by the employer and being Indian makes his visa sponsorship more challenging than if he were from another country with fewer people emigrating to the US.

It also makes the difference in the sense that the wait list from H1B to Green card is the toughest for Indians (and probably Chinese) compared to other nationalities due to the 7 % limit per country in terms of granting Green cards.

I think the wait for the lowest priority EB3 is like ~150 years as of now ?

I came back to India after working in USA on an H1B for 6 years due to the uncertainty. I do miss working there but not much can be done unfortunately.

We cannot do much that we are 1/6th of the world population , hopefully Green card limit will be raised at least to the proportion of the country's population (or some other logic that makes more sense). I have known a few people from Nepal and Bhutan working in easier jobs who are well settled there now. They got the green cards because they are smaller countries. Nothing they do is really high skilled but then these things can get subjective so i do not want to wade in that debate.

It took me 2 years to really negotiate my first salary raise and it was not a lot either.

Could you please talk more about your experience of moving back especially after 6 years of tech in US?

Not exceptionally good, now thinking of migrating to Canada. But that is because i do not have a big social circle, finding it difficult to get married in India too and just love nature and clean air a lot. It is the small things that make it difficult for me, the driving, the commotion but some people thrive in that scenario.

It is really a YMMV situation though. I know rich folks have some advantages in India (nannies, drivers, social status etc.) that they do not get easily outside. I do not think it is easy for someone who is introvert to adjust although big cities have changed a lot.

Because the green card line is longer for indians due to American foreign country quotas?

Read the post. He can't quit the job because of his visa.

He can quit his job if he wanted to

He can also switch to another company that will transfer the h1b visa

He can quit but then has to leave the country or find a new job very quickly.
