Changed Your Mind After a Residency Letter of Intent?
Told a residency program it was your first choice and now it isn't? Rank your true first choice first: NRMP rules, the algorithm, a two-line correction.
Changed Your Mind After a Residency Letter of Intent?
Rank your real first choice first. A letter of intent binds you to nothing. Your certified rank order list is what binds you, and NRMP tells you to build it on true preference by 9 p.m. ET on Wednesday, March 3, 2027. If your letter said "I will rank you first," send that program a two-line correction before you send anyone else a first-choice letter.
Our view: what you wrote in the letter has to stay true, and the correction keeps it that way. Ranking the new first choice first isn't disloyal. It's what NRMP asks you to do. What damages your word is a second "you're my first choice" letter while the first one still stands.
Every NRMP and specialty document quoted below was checked on November 7, 2026. The general rules for these letters are in the residency letter of intent rules for 2027.
What binds you and what doesn't
| Thing you did | Does it bind you in the Match? | Source |
|---|---|---|
| Sent a letter of intent | No. No NRMP document we checked makes a letter binding | MPA, Code of Conduct |
| Certified a rank order list | Yes: certifying confirms your agreement to "Adhere to the binding commitment to accept an appointment if a match result(s)" | MPA section 7.2 |
| Matched to a program | Yes: "a binding commitment exists for the program to offer a training position to the applicant and for the applicant to accept such position absent a waiver from the NRMP" | MPA section 4.0 |
Source: 2027 Match Participation Agreement for Applicants (MPA). Before the deadline you can still change the list. The MPA says applicants "may modify their lists multiple times before the Rank Order List Certification Deadline," as long as they recertify.
Why ranking the new first choice first is the rule
NRMP's Rank Your Programs page says: "be sure to rank programs in order of your true preference and not where you think you will match." The page makes no exception for a letter you already sent, and neither does the Code of Conduct for Applicants.
The algorithm is also why moving the old program down costs you nothing there. NRMP's algorithm page says it first tries your most preferred program. "If Applicant A cannot be matched to this first choice program (because the program doesn't also prefer Applicant A), an attempt is then made to place Applicant A into the second choice program, and so on."
Constructed illustration, invented for this guide. You wrote to Program A in January saying you would rank it first. After a February visit, you prefer Program B. Rank B first and A second. If B ranked you high enough to take you, you match B, which is now what you want. If B didn't, the algorithm moves to A and places you there exactly as if A had been first. You lose A only if B takes you.
Changing your mind after a visit is ordinary. In NRMP's year-one report on the voluntary rank list lock pilot, 57.3% of surveyed applicants who attended post-interview visits said a visit led them to move a program higher, and 21.5% moved one lower. That survey covered only internal medicine, pediatrics and vascular surgery applicants in the 2026 Match.
What MPA section 6.3 means for the letter you already sent
Section 6.3 makes you responsible for "the completeness, timeliness, and accuracy of all information provided to programs," including "All written, electronic, and verbal information provided to programs and program representatives throughout recruitment." It adds: "Applicants who submit incomplete, misleading, false, or plagiarized information may be deemed to have violated this Agreement."
Applying in pediatrics? The pediatrics letter of intent rules set the one-program limit in full.
What the agreement does not say: whether a preference that was true when you wrote it, and changed later, has to be corrected. We found no NRMP text on that question, so the answer is unknown.
Our recommendation: correct the letter if it made a specific ranking promise ("I will rank you first"), because it is now information you gave a program that is no longer accurate. Don't correct a letter that only described interest ("among my top choices," "I will rank you highly"), if that is still true.
The countercase: in a specialty that discourages post-interview contact, a correction is one more email the program didn't ask for. Pediatrics, for example, says letters of intent "should only be sent to one program" and "Programs are not expected to reply to such communications" (APPD 2026–27 recommendations). Our reading: if you sent a pediatrics letter of intent to Program A, the one-program rule leaves no room for a second one to B while the first still stands. The correction is what makes a new letter possible.
Three situations, three moves
| Your situation | What to do |
|---|---|
| Your letter said "I will rank you first," and the deadline hasn't passed | Send the two-line correction. Then, if your specialty allows letters, you may write to the new first choice |
| Your letter described interest only, with no ranking promise | No correction. Rank by preference. Write to the new first choice only if your specialty allows it |
| The old program's list is locked (lock pilot) or it is after March 3 | That program's list can't change, and after March 3 no list can. Your own list can still change until March 3. Send the correction to keep your word, not to change an outcome |

Lock-pilot programs, in internal medicine, pediatrics and vascular surgery only, "cannot uncertify and edit their ROL under any circumstance" once locked. The target is "11:59 pm EST on Monday, February 8" (2027 process and timeline). NRMP's pilot FAQ says R3 shows a lock symbol for each locked track.
Should you send a letter to your new first choice?
Only after the correction, if your first letter promised first place. Check three things first:
- Your specialty's rule. Dermatology and plastic surgery ask for no post-interview letters. Family medicine, pediatrics and psychiatry discourage them. The full list is in the 2027 letter of intent table.
- The new program's lock status. A locked list can't move.
- A reason from what you learned. "I changed my mind" isn't a reason the program can use. Name what you learned on the visit or the interview day. The residency letter of intent examples show the structure.
If the change came from a second look, the residency second look guide covers what each specialty allows around those visits.
Constructed correction email
Constructed example, written by us, not a real applicant's email. Context (invented): Meera Ghosh told an internal medicine program in January that she would rank it first. In February she decided to rank another program first.
Weak version (72 words):
Dear Dr. Brennan,
I'm so sorry, and this is a hard email to write. After a lot of thought and a visit to another program in my home city, I have decided to rank that program first instead of yours. I truly loved my interview with you and I hope you will still consider ranking me highly, since your program is still very close to the top of my list.
Meera Ghosh
Revised version (49 words):
Dear Dr. Brennan,
In January I wrote that I would rank your program first. My rank list has since changed, and I want my earlier letter to be accurate. Your program remains one I would be glad to train in, and I will rank it.
Thank you, Meera Ghosh
What changed:
- No other program named. MPA section 6.4 gives you the right to "Keep confidential all information pertaining to ranking preferences", and to keep confidential the names of programs you apply to. You don't owe anyone the name of your new first choice.
- No request. "I hope you will still consider ranking me highly" asks the program to act on its ranking. The Code of Conduct says applicants "must not solicit or engage in post-interview communication for the purposes of influencing or ascertaining a program's ranking intentions."
- One true statement of where things stand. "I will rank it" is true and specific. Leave out "very close to the top," which is the same kind of claim that needed correcting.
- No apology paragraph. Changing your preference is allowed. The correction fixes a sentence. It isn't a confession.
Questions about changing your mind after a letter of intent
Is it a Match violation to rank another program first after a letter of intent?
No NRMP rule we found makes a letter binding. The binding commitment attaches to your certified rank list and to a match. The accuracy duty in section 6.3 is why we recommend the correction.
Will the first program find out?
Your rank list is confidential under section 6.4, and no program may ask you for it under section 6.5. NRMP publishes nothing on what programs say to each other.
Should I call instead of emailing?
Email. It goes to the same person who got your letter, and it leaves a record of the correction.
I already sent a second first-choice letter. Now what?
Correct the one that's no longer true today, with the same two-line email. Then make sure your rank list matches the letter that stands. After the Match, changing your mind is no longer a letter question: you would have to request an NRMP waiver, and a change of specialty doesn't qualify for a PGY-1 match.
