Is it any 8 years, or continious 8 years? In most places, the requirement is for continious, which is a tough ask. Imagine not being able to leave the country for almost a decade.

And you need a reason to get residence permit. In most cases there are few: living with spouse, reuniting with family, working, studying, or doing business. Of those, only work, study and business are the ones that are realistically achievable.

For work, there’s usually also a requirement for employeer to prove that there are no natives available to fill the role. This is a tough process, which takes a lot of time and no guarantee it’d even get approved. So, not many employees even bother unless you have exceptional skills.

For study, you would have to actually study to avoid expulsion, while somehow earning enough on some part-time remote work to support yourself (or have enough savings to support yourself for years). And then, bachelors is not enough so you must go for PhD. Meanwhile, in both above cases you have to also learn local language. I’m sure there are people who could pull this off, but, again, it’s quite exceptional.

Last is business. Usually the requirement is to invest somewhere in the ranges of $100k to $500k into local economy. That’s not filthy rich, but, for context, for Russian it’d take 3 years of fighting on the frontlines to earn as much, with a wage considered good enough to risk dying for… And then the country can still deny you permit without any reason.

It’s because of this, most people I know, who chose to leave the country keep their passports and either settle in Armenia and Georgia with 182/365 days renewable visa-free entry, or run circles between Serbia-Montenegro or Thailand-Vietnam.

There are also interesting opportunities with digital nomad visas, but, again, the requirements out of reach for most.

But for oligarchs, this is pennies. They can buy a few outright, then fly private jet to the US as tourists with pregnant wives, get children born there, then send them to study in London. Apply for family reunifications, bam, theyre now citizens of US and UK, in addition to all previous ones.

I assume if the Russian maintainers showed that they’ve passed the citizenship examinations and their different citizenship is only a matter of time

It’s the other way around. You have to live for X years to be eligible for the test. Given a common requirement of 5 years, they would have to have started this process 2 years before the war broke out.
