For your information. I just came across a posting on SDN. An international student gain entry to a US med school after three tries. His stats: GPA 3.9 and Mcat 38. He commented that only top med schools entertain international applicants and it is very hard to get in.
3 tries means 3 valuable years of your time and at the end, when it is time for residency, you will have hard time to find a PD to take you because of the international status requires a lot of legal work to get that work permit. No wonder all my international physician friends all went to Family Practice.
