I’ve received some questions about the timing of letters of intent (LOI) for medical school and residency. I recommend the following:
Send the letter as soon as you complete your interview. That way you can knowledgeably discuss your impressions of the institution, while attempting to positively affect your candidacy before being evaluated by the committee. (As you usually don’t know when your application will be discussed, sending immediately after your interview is important.)
Although I recommend sending hard-copy LOIs, if the institution has not prohibited sending emails to the admissions committee/residency administration, there is no harm in emailing your LOI in addition to sending the hard copy.
Contact me for help editing your LOIs.
