I doubt that embassy will issue a visa for a student without toefl. No wonder how strong your documents are. S/he will be just wasting money by applying for a visa without a toefl ( if s/he is trying to come to the US as a student). I have to take TOEFL here now. Well, I did not come as a student so I was able to get a visa easily. Tell your friend no need to be afraid and take a toefl. They have somany inst. in ktm who will prepare for the TOEFL.
