The UK ILR does not allow you to leave UK for more than 2 years. Otherwise, the ILR lapses. If one happens to work in the EU, or anywhere else in the world, they would have to come back to the UK within that 2 year period. There are similar restrictions on the US green card.
Hence, it makes sense to actually get a UK/US citizenship. Plus, there's also the 'loyalty factor' towards your new home-away-from-home.
You can still have an OCI and enjoy virtually all the rights of being an Indian citizen. It is essentially dual citizenship.
Most Indians living abroad are as patriotic as Indians living in India.
And with the salaries in the tech sector in India rising, as they are, there's actually less of an incentive to leave India in the first place. At least for the current generation.
People who left India earlier are also coming back, especially in places like Bangalore.
I'm asking why get UK citizenship at all and not just quit and work in India? Why showcase loyalty at all?
As I said every Human being is different and I'm sure their are Indians who are loyal to their country and would never leave + Indians who would wish to return home permanently. Theirs no point in outright claiming that every Human being who's an Indian has the exact same thought process but the statistics still do not lie.
Every year more and more Indians are migrating abroad, assuming the country allows it.
Idk about USA or UK primarily because the migration process is difficult but Australia's migration process is extremely easy depending on the state.
NSW, Queensland, Tasmania(Offshore) and WA is hard, but SA, ACT and VIC state Nomination is extremely easy to acquire for offshore applicants.
For ACT if you're young, you can study a degree from a uni and just apply for the PR graduate pathway which has a 100% success rate for PR assuming you don't have a criminal record.
For SA, you just need 3 years of work experience and pass a skills assessment that you can apply online to get Nominated and for Vic, you just need to write a ROI and any online immigration lawyer will write it for and ensure you get it.
^^ Case in Point, Aus has made it easy to Migrate to Adelaide, Melbourne and Canberra and India is currently the biggest benefactor of this.
India is now the 2nd largest migration population in Australia after English and English doesn't really count since they've always lived here, their hardly any aboriginals left.
Every year the migrant population is increasing and more and more people are applying so based of pure statistics and numbers, it's doesn't seem like More and more Indians are returning home.
The numbers show their more people migrating then actually returning home.
Can't speak for UK and USA as idk much about them from a migration perspective.
