Acquiring Polish citizenship by naturalisation [40]
So he was an ethnic Pole
there is no thing like "ethnic Pole"
Spoken like a person who has never had their life blighted by mass immigration. Lots of people initially in favour of letting in Poles and other Eastern Europeans to the UK said some similar things. Lots have now changed their minds because they have taken out more than they have put in.
well- even now Ukrainians are "taking Polish jobs" in the low waged field work (someone has to pick apples or dig up kartofle)
and as I wrote- as long as immigrant are not committing crimes and are working, i can hardly see anything against it.
and, unlike in UK, in Poland you have to work to be able to get benefits. Good!
