Yes there is, but it's not the card with photo etc.. anymore, it's just a crappy bit of paper. I got mine last year.
When is a karta not a karta? When Polish bureaucrats are involved with it....
Do you know what year this was? Because when I last checked the rules when I got my karta pobytu it said that EU residents could apply for permanent residency once they had been here for 5 years.
I think it was 2005 to 2006. But I could be completely wrong about that.
