I apologize if this is the wrong section so mods feel free to move.
My girlfriend's friend/co-worker has been e-mailed by another male worker threatening her of rape. The e-mail says things like "I'm eventually gonna f*#k you!" and other things like that. This is not the first time. He stalks her and knows where she lives, calls her cell phone..etc..etc. She is scared and has nowhere else to go to. She told her boss/manager about it and he does nothing whatsoever. The manager just doesn't really care to be honest. The main problem here is that she is not a legal citizen of the U.S. so she is afraid to call the police. Is there anything she can legally do to protect herself without being deported?
This is in California.
