So I am doing multiple sub-is which is complicating things. So just did IM. I requested a letter and he said yes...however I don't know what specialty I am going for...should I just say IM and have him upload the letter and then change it later if it needs to be geared toward a different specialty? or should I have him upload the letter later, when I know what specialty? or should I have him write a general letter?? Please help. thanks
