Hi,
I am an international student applying to PhD programs in the US. Some universities say that they do not require a TOEFL score from international students who studied at universities where the language of instruction is English. I suppose this includes the English speaking universities outside English speaking countries. I am studying at a university where English is the language of instruction. Does this mean it is absolutely OK not to submit a TOEFL score, or should I still send a score to strengthen my application?
