Law / Polish visa expert? Japanes moving to Poland to study Polish. [43]

I found this blog post about the Karta Pobytu, might explain for you somehow

britishinpoland.com/blog/2008/03/5-year-registration-karta-pobytu/

Basically it's a "card of stay" that allows you to register for a 5 years period. You can only apply for it after staying in Poland for 3 months, with local registration.

Love / Please help in this long distance relationship (I live in Canada, she is in Poland) [12]

I suggest going for an exchange study, or apply for a language course, if you really want to be with her.
I ended my 2,5 years relationship with an Aussie guy whom I met for only 6 weeks. We could still drag on, but I see there is no chance for us to meet.

So, you know, think it through. If you don't think it can't move on, better let it end soon.
