I'm wondering if someone can help me get some things straight. I'm going to medical school on the HPSP through the Air Force. Right now (and I know it might change after I start school), but I am interested in internal medicine and then doing a cardiology fellowship. I know that there are IM residencies available that are 36 months in length, but they appear to be categorical residencies (no internship). If not traditional internship is done, how does this work with AOA licensing. I plan on making the military my career unless i absolutely hate it, and I dont want to be unlicensable once I get out. Thanks for any help.
