No, not at all. In fact, compared to representation in the general population, asians (including Indians) are represented disproportionately in greater numbers in the Ivy’s. Therefore, as an Indian, you have a greater percentage chance, when measured against other asians, of being admitted than does a Caucasian, when measured against other Caucasians, or a black person, when measured against other blacks.
However, since there are so many more asian applicants, your portfolio of achievements will need to be significantly better than average in order to be admitted, because you are in essence competing against a larger and better prepared (on average) pool of other asian applicants.
