I didn't know Poland won't take any migrants have you a link for that.
It's not true that Poland does not take refugees. It does. Not as many as the UK per head of population but Poland is a poor country. Compared to more comparable countries such as France or Germany, the UK receives extremely few refugees. We should do more to accept our burden.
As for migration, while there is some inward migration to Poland, the net migration figures have been negative for some time although the balance is shifting towards being more neutral in more recent figures.
