To the OP and others with similar questions.
1. The total residency spots in the country is more than all the US allopathic students and US osteopathic students combined. If you are competitive, you will get a spot, likewise, if you are not competitive, you will NOT get a spot regardless.
(When I was associate program direction, I removed DO's applicant from my desk who were not competitive)
2. There are more US osteopathic students than there are osteopathic programs.
3. A good number of Osteopathic residency programs unfortunately may end up closing, despite what the AOA and its respected colleges say. Like-wise, CMS allows "X" number of spots. The closed osteopathic spots will be gobbled up by the existing ACMGE programs.
4. The ACGME programs on probation for whatever reason will also be revamped if not closed and its spots given to bigger institution.
5. You will basically be competing against US allopathic students and US osteopathic students, unfortunately, the IMGs will always have their stigma regardless. It is true that most IMGs fill residency spots where US allopathic and osteopathic students don't want to go.
6. Yes you can apply to MD or DO schools, I would hesitate on applying to off-shore schools.
7. Osteopathic-trained and osteopathic boarded physicians "WILL BE CONSIDERED" for PD in almost all the specialties except a few. However, note on the phrase "will be considered". That will be dependent on the Chair of the department and the other directors. Politics will play a lot into this portion. Of course, if you know people, then it wouldn't be a program.
8. All Osteopathic residents in a current AOA program with ACGME approval will be allowed to sit for the ACGME specialty board, if they are accepted into specialty field.
(i.e. If I graduated from an AOA OBGYN program, I can apply for an ACGME OBGYN sub-specialty fellowship program and be accepted. However, I will not be able to sit for the sub-specialty board exam)
(The governing college and the board examiners are TWO DIFFERENT entity)
9. All the stats and numbers that people quoted on this thread is pure garbage. Its irrelevant and does not help make any decision because unfortunately, NO ONE really knows what the outcome will be. People can only assume.
Good luck to the OP and all others stuck in his/her situation. Please take note of point#6.
