You need to have a TOEFL score 100+ if you want to get into the top 50 schools. It can be lower if you have other things going for you, i.e., teacher recommendations, extracurricular activities, etc. US schools stress BOTH academics as well as extracurricular activities, they expect to see the followings:
• High level of English
• Good grades
• Good test scores
• Outstanding extracurricular activities
• Good interview
• Good essays
You will have to be well prepared in these aspects.
