First, you will need to send your credits to a transcript services company such as Josef Silny or WES (they are the most popular) once you have your course by course evaluation you might contact the school you are planning to apply and find out with them which course are Ok and ask directly to each school if you need to repeat and/or retake other classes, However, not all schools will accept your international transcripts, so you are in disadvantage compare to other people. On the other hand, re-doing the pre-reqs will give you more opportunities, but it will cost you time and money. Anyway, the fact that you have a master degree will demonstrate them that you have a wide background within the field. Good Luck👍
