People keep talking about Indians moving abroad, where are they going?

Everyday there's countless posts about people leaving India for "greener pastures". Where are they even going? Popular destinations like Canada, Australia, UK etc are tamping down on immigration. The US tech job market is currently fucked although it's gotten marginally better for highly skilled and experienced engineers. Where are all these people even going? You can't just be rich to leave the country. You need visas and jobs to stay there. You can go abroad as a student but the ones that went a couple years ago are currently struggling. What gives?
