The application process begins with an application to the Electronic Residency Application System (ERAS). We don’t accept paper applications.


You must have graduated from an approved U.S. or Canadian medical school or hold Educational Commission for Foreign Medical Graduates (ECFMG) certification if you graduated from a medical school outside the U.S. 

If you graduated from a foreign medical school, be sure your visa status will permit you to complete your training and that you qualify for Pennsylvania state licensure before applying.

Fellows are expected to become certified in internal medicine by the American Board of Internal Medicine at the earliest opportunity and certainly before completion of their fellowship.
