Can someone whose first language is not English bring an interpreter to the assessment, as well as another person for support?
Yes, you can bring an interpreter, and yes, you can bring a companion, however, I cannot find any advice as to whether you can bring an interpreter and a companion at the same time.
The only thing I can suggest is that you raise the problem with ATOS when the medical is arranged.

Nothing on this board constitutes legal advice - always consult a professional about specific problems
When i had my medical, there was someone there who waited for their interpreter to come she also had two other people with her , but only the interpreter went in with her i think Atos arrange this
