From what I read there, you just need the long term residency for 3 years.
That only if you marry Polish citizen
Am I mistaken thinking that I can get a long term residency right away? I already have a permit to stay in Europe and I'm just coming over to Poland and switching it for long term stay visa. I thought from then on it'd be 3 years...
Other European countries are irrelevant. Here you have conditions for Long term permit. It's 5 years:
Even if it's 50% for school years, 4 yrs would count for 2 yrs, then I'd have to work one full year in Poland to get the 3rd year, no?
5 - 2 = 3 more
From what you say it seems like I need to spend ~5 yrs just to get the long term stay visa.
Long term residency, not visa. Visa expires and this residency permit doesn't
Which I understand, because some countries will issue "permanent resident" visas only after 5 years
I think all EU countries because this permit is called "long-term resident of the EU"
