How hard is it to get into an Anatomical and Clinical Pathology Residency with a DO Degree in order to become a Forensic Pathologist?

The NRMP match statistics for 2012 and 2011 ranked it in the "low competitiveness" category. In 2012, about half of path positions were actually filled by IMG's. But from 2008-2010 it was ranked in the "intermediate competitiveness" category. Even so, a DO degree shouldnt hinder you from obtaining path so long as you have decent or better board scores. Also, as will any specialties, you can always place somewhere. Comptitiveness varies among programs too. Do relatively well on your board exams and apply broadly, you'll land a path residency.
