Is it normal that i'm having some trouble fitting in?

I'm a recent immigrant and I'm having some trouble fitting in. For some reason, everyone has been avoiding contact with me. They are all wearing orange suits and put me in a big plastic encasement with food that, while technically edible, is missing key nutrients such as Arsenic and Aluminum. is it normal that immigrants to your planet get treated this way? I was under the impression this was a peaceful world where everyone gets along.
