You probably want to do that when you are young and healthy.

I am already an immigrant, so I don’t have the full social security in the country I currently live, and yet I have to pay all taxes and social charges. If and when I won’t be able to sustain myself, they’ll just kick me out. And I have no interest in returning to my home country (Russia), for obvious reasons.

If you can't get the pension you pay for, you are usually entitled to a refund for your pension payments. At least that's the case in Germany.

If I move to another country, yes. I have no intention to, but I can’t get a permanent resident permit here for a multitude of reasons.

Perhaps I can lend a hand. Feel free to email me at [email protected]. I'm familiar with all the challenges immigrants face in Germany.

Ah, in that case it makes a lot more sense, you have much less to lose.
