If they are not going to learn for Tatars how to live in Poland they will have problems ...
As I read many Chechens don't stay in Poland despite oficial status. They leave for Germany and Belgium to become ilegals. Quite a surprising behaviour. Why not to spend some 6 years in Poland, receive citizenship and move longer?
they live mostly in Bialystok
What is the reason of such choice. Bialostok seems to be a conservative region that doesn't like new residents.

That is not because they are muslims. they are from mountains. That's why they are divided into tribes (they call it tejp) that have mutual assistance and quite isolated even from other Chechen tribes (the custom of mountanous life - you can see similar things among other ethnies in mountains).
Besides that agriculture in mountains was connected in the past with insecure climate and hunger death thread made them visit their neighbours and taking hostages in order to receive meal in exchange.
My Georgian friends told me that was a common practice with mountain residents in also in Georgia.
Tatars from Crimea also had some habits of the sort in the past but today they abandoned old traditions and mentality.
