as a grad of a do residency program you have all the same rights as any md grad in the same field. the ama considers the md and do degrees to be equivalent in the practice environment. if you are a do med school grad you can apply to both md and do residency programs. many do residencies also qualify you to take the md specialty board exams in addition to the do boards, hope that helps.basically, when you are out of school there is no difference in practice opportunities.
