I'm doing the opposite. I'm an American now living in Russia and will apply for long term residency then may apply for citizenship at some point once my language skills are better. I joke with my wife that in return for the green card I helped her earn, she helps me get a red card.

Russia has very low taxes for contractors, so that combined with the American foreign earned income tax credit results in tremendous tax savings. Also, I'm on the Black Sea so the weather is better than the rest of Russia. Downside is the political situation, obviously.
