step 1. apply for a master degree from a english speaking country. don't only focus on america. try canadian or australian universities. get good grades there.
step 2. work for several years in fields related to accounting. not too many years, but at least 2 to 3 years.
step 3. retake GMAT. by that time you apply for american b school, your GMAT will have expired. but that's to your advantage. you can retake it without having any record left.
