TOEFL.
I don't recall that anyone has to take a TOEFL test UNLESS he/she doesn't have English as a first language.
*If they live in a country that has a native language like Danish, Norwegian or anything other than English then they will unfortunately have to take that test.*
* Unless of course they just recently moved to another country, i.e. born in USA and then moved to Norway etc.*
*And if anyone doesn't know this yet, TOEFL means Test Of English as a First Language. (If memory isn't failing me).*
