I have a quick question regarding a LoR: I am finishing up an ENT away rotation this week, and have already been told that I will be getting a letter from where I am rotating, but it likely won't be finished for another 1-2 weeks after I leave. My question is whether I should wait for this letter or designate another (non-ENT) letter to my application to get a 4th one out there as residency interview invitations go out. I am just worried about only having 3 LORs in my application currently (2 ENT, 1 non), and am wondering if not having 4 in will affect my chances of getting more invites.
Thanks in advance.
