Thankyou Rip. I am proficient in the language. Though, I have don't have a good accent. Should I give the test, studying for 2-3 days?Many don't require TOEFL if the language of instruction at your institution is English. They just require you to provide a letter from you school saying that.
Of those that do, some require a total of >100, others have a cut off value for speaking section. NIH had 28 or higher, some others like Umass had 24 and so.
