I guess it's like that everywhere. I studied in Poland with a friend from Nigeria, and the amount of hoops he had to jump through every 6 months to extend his stay permit was unreal, even despite the fact that he spoke fluent Polish, had a part time job and got really good grades. Each time he was asking to extend his permits, it could very easily be denied for whatever reason and he would have to abandon everything and be flown back to Nigeria. Also, he saw hostility towards him in every office he went to.

Meanwhile, if you're illiterate but from Chechnya, you get a free apartment and welfare checks here courtesy of the taxpayer, because apparently "the situation is political". It's ridiculous.
