I received my IA recently and CHC London requested some extra documents. I have not taken the above exams although I am not English. I am from an English speaking country though. I think I included a TOEFL results slip I took many years ago before entering university. All my academic work has been done in England and the US.
I have sent all documents they requested already.
My question is, do I need to take IELTS although they did not request for it?

Just to be on the safe side really.

Many thanks for your help.
