I know people who have been waiting around 5 months to get their karta pobytu which is valid for one year only. The polish bureaucracy is one of the worse in the European Union and it is impossible to try to ask some kind of help from the pathetic and useless bureaucrats. They got a very frustrated and miserable life during and after the communist regime and they want to transmit that to other people and make their lifes miserable.

In other EU countries where people DO want to emigrate, if you have all the papers in order it is a matter of days to get the visa/resident permit. This does not apply in Poland, you can have everything in order and still, the process for someone to get the karta pobytu will take months !

You were thinking about your free of charge entry to the EU?
