Is that true even for visiting? I am Indian and have wanted to visit Poland and the region for quite a while. I did find rural Germany quite ok except communication.
You’ll be fine for sure in touristy areas and big city centres.
There are Indian people living and working in Poland, so it can’t be too bad. Right wing media say nothing of racist attacks. Left wing media describe them all the time. There are vocal nationalists, most of whom never go past their grumblings.
I raise it as I’d be somewhat concerned sending a non-white or job-straight friend into rural Poland.
