I've been studying the subject a lot lately. It's not particularly easy to just 'switch sides' physically. Even the handful of nations who will sell citizenship (e.g., Turkey) do want upwards of half a million $$$.
You're studying something irrelevant. You don't need citizenship to pursue freedom in the
dictatorship country of your choice. Russia will happily hand out permanent resident permits to pretty much anyone, all you need is a job.
The last thing I need or have any interest in is a job.
You really need to learn more about how your favorite country functions. Having a job as a requirement to get permanent resident status doesn't mean you actually need to work that job, just lubricate the appropriate cogs in the machine.
But Russia doesn't sell citizenship as best I can tell.
Get the above and wait 5 years, that's all it takes.
And probably some Russian?
AFAIK not for residence. Would need it for citizenship. But in any case learning the language of the country you live in would be prudent.
