2027 ERAS Letters of Recommendation for IMGs

Why the letter carries so much

A letter of recommendation is one of the few parts of your application in which another professional evaluates you in narrative form — ideally someone who has watched you take care of patients. For an international graduate, it does something no score can: it puts a U.S.-based physician's name behind the claim that you can function in a U.S. system. That reference frame is exactly what a program director is missing when they read an unfamiliar transcript — and it is why a specific, first-hand letter reliably sits among the factors programs weigh most heavily.

The corollary is what most applicants get wrong: a letter's strength comes from how well the writer knows you, not from how famous the writer is. A detailed letter from the attending who supervised you for a month beats a generic one from a department chair who met you twice.

Who to ask

In rough order of value for an IMG:

Attendings who directly supervised your clinical work. They can speak to clinical reasoning, judgment, and how you work on a team — the things programs actually want to know.
Hands-on U.S. clinical experience generally gives a supervisor far more to evaluate than a passive observership. A hands-on rotation lets a supervisor judge your reasoning and write a specialty-specific letter; a passive observership usually yields only a letter confirming you attended. If your USCE was an observership, you can still earn a real letter by presenting cases, discussing management, and making yourself useful — see U.S. Clinical Experience.
Research mentors and PIs, especially if research is part of your story. A U.S.-based research letter is a valuable U.S. reference — just follow a program's stated requirements when it specifically asks for a clinical letter.
A department chair or clerkship director — some programs specifically require a chair or departmental letter, so treat that as its own slot rather than one of your clinical letters.

What makes a letter strong

The AAMC's own guidance to letter writers is a useful blueprint for what to steer your writer toward. A strong letter:

States the relationship — the writer's role, and how long, how often, and in what setting they worked with you. It gives the reader context for the praise.
Shows behavior, not adjectives. Not "she is professional" but "when [situation], she [did X], which [led to Y]." Specific episodes are what survive committee.
Benchmarks your readiness — ideally to a level a program recognizes ("already functions at the level of an intern because…").
Compares you to a defined peer group ("among the top students I have supervised in ten years"), which lets a program calibrate.
Covers both clinical skill and professionalism, each illustrated with a concrete moment.
Ties your strengths to the specialty you are applying to.

A note on standardized letters

A few specialties use a standardized letter instead of a free narrative. For 2027, the AAMC Letter Writer Portal carries portal-native standardized forms for Dermatology, Urology, and Plastic Surgery–Integrated — request the correct specialty so your writer receives the right form. Orthopedic surgery uses a society form (the AOA eSLOR) that is completed and then uploaded into the ERAS portal. And note that Emergency Medicine and OB/GYN no longer run through ERAS at all — both moved to ResidencyCAS, each with its own standardized letter (EM's SLOE via CORD), so applicants there follow the ResidencyCAS process instead. These are hard for IMGs to obtain because they require a U.S. rotation in the specialty. If you are targeting a SLOE-driven field, building that rotation in is not optional — factor it into your timeline.

How to ask well

The ask is a skill, and doing it well is most of the battle.

Ask early — while the rotation is fresh, and ideally before you leave it. For IMGs on a short U.S. rotation, request the letter before you go home, while the attending still remembers your cases.
Use the two-part ask. Don't ask "would you write me a letter?" Ask "are you able to write me a strong letter of support?" It gives a reluctant writer a graceful way out — and a hesitant "I could write you something" is a no. Thank them and move on.
Give at least four to six weeks' notice before any deadline, and ask in person or by a personal note — never a mass email.
Hand the writer a packet. Your CV, your personal-statement draft, the specialty and a sense of your program list, the submission instructions and deadline, and — most useful of all — two or three specific moments from your time together that you'd be glad to see mentioned. You are not writing the letter; you are making it easy to write a specific one.
Follow up gently and close well. Send the packet within a week of the ask; a single polite nudge about two weeks out is fine; send a genuine thank-you once it's uploaded.

Lukewarm letters & red flags

The letter that quietly sinks an application is not the negative one — those are rare — it is the faint-praise letter. Phrases like "a good candidate," "a solid student," "showed improvement," or "will become a competent physician" read to a committee as: not a problem, but not special — a backup. In a competitive specialty, a generic letter can hurt you more than simply having one fewer.

What programs read as a warning:

A letter that reads like a rotation summary and could describe anyone.
Conspicuous silence — when a letter omits the clinical skill or the professionalism a reader expects, the reader assumes the worst about what was left out.
A non-waived letter (see below).
A missed deadline, which can leave your file incomplete when a program first reviews it — so ask early, watch the upload status, and follow up professionally.

The mechanics — the 2027 Letter Writer Portal

The flow, and who does what:

You create the request in MyERAS — the writer's name and email, the target specialty, the letter type, whether it's a department-chair letter, and your waiver choice. That generates a unique letter request the writer receives. Once you confirm an entry you can't edit it, so enter it carefully.
The writer uploads directly — through a secure link as a guest, or from an AAMC account. If you waive your right to view the letter — the strong norm, and what programs expect — your writer uploads it and you never touch it; only a non-waived letter may be uploaded by you. Either way, every upload is watermarked with the uploader's name and a timestamp, and programs can see who uploaded it.
You assign uploaded letters to programs in MyERAS. You control which letters go where — up to a maximum of four per program. Some programs ask for fewer, or for a specific mix (such as a required chair letter), so read each program's requirement rather than defaulting to four. Most programs ask for three or four letters; as an international graduate, make sure one or two of them come from U.S. clinical supervisors.

When to line them up

The season compresses fast. For the 2027 cycle, MyERAS opens for building on June 4, 2026 (you assign letter writers then), you can submit to programs on September 2, 2026, and programs begin reviewing on September 23, 2026. Because everything you submit in those first weeks lands with programs at once, your letters should be ready before you submit — which means asking in late spring or early summer, and completing any rotation-based letters before you leave the rotation. You can add letters after submitting — ERAS allows it — but a program may review your file the moment its window opens, and letters that arrive after that are not guaranteed to be seen. Treat “ready before you submit” as the goal, not a system rule.
