We have some Ukrainian immigrants (the official estimates are ca. 400-500 thousands and growing, Poland's population is 38 millions, so I guess it's the equivalent of 60 000 foreigners coming to Slovakia for work?), some Turks and Vietnamese, but nothing massive. We had (still have?) Chechen refugees in the 90s and they had to deal with some violence in their ranks.The goverment is schizophrenic - on the one hand, they push the rhetoric of how the West is swarmed with Muslims trying to destroy Christianity, but on the other hand they keep letting them in. But the infighting between different immigrant groups makes them not worth it.
