Hi, I am an IMG. I signed in ECFMG for the step1 this Feb. ECFMG mailed a letter to my previous medical school to confirm my diploma. I let my friend to check it but they said they never saw this letter. Does any one know that which department or office ECFMG mail the letter to the medical school, or what kind of address ECFMG used to mail the letter to the medical school? I appreciate your answer very much.
