Oh, thank you so much @San_Francisco . That thread seems full of good info, will read it.
Can you please explain me why I should not forget about 1st pillar AHV/AVS?
And also, for the 2nd pillar, why would I not try as hard as possible to cash it out? Even if with VIAC you mentioned. After all, I have been living 3yrs in Switzerland, how much should I expect to get once I retire from this? The equivalent of 30 CHF per month? 100 CHF? Does that really justify not trying to find a way to get that money back and use it for something more lucrative?
Or am I missing something?
