Ultimate Guide to LORs for IMGs Applying to Transitional Year Residency

Understanding the Role of Letters of Recommendation in a Transitional Year Application

For an international medical graduate, letters of recommendation (LORs) can make or break a transitional year (TY) residency application. As an IMG, you may already know your scores, clinical experience, and visa status matter—but in a competitive Transitional Year program, your residency letters of recommendation often become the deciding factor between two otherwise similar applicants.

Transitional Year residency is unique: it attracts a mix of applicants—those headed into advanced specialties (radiology, anesthesia, dermatology, neurology, radiation oncology, PM&R) and those still exploring options. Program directors rely heavily on LORs to answer one key question:

“If I bring this IMG into my TY program for one year, will they be safe, teachable, reliable, and pleasant to work with?”

This IMG residency guide will walk you through:

• What makes a strong LOR specifically for Transitional Year
• Who to ask for letters (and who not to)
• How to get strong LOR from U.S. and non-U.S. rotations
• Practical steps to ensure your letters actually help you match
• Common mistakes IMGs make and how to avoid them

Throughout, the focus is on the realities faced by an international medical graduate targeting a U.S. Transitional Year residency.

What Makes a Strong Transitional Year Letter of Recommendation?

Not all positive letters are equally helpful. A strong LOR for a TY program does three things:

1. Clearly vouches for your clinical competence
2. Demonstrates your reliability and professionalism
3. Communicates that you will be easy to work with on a busy inpatient service

Key Elements Program Directors Look For

Program directors reading hundreds of LORs learn to skim quickly. They look for:

• Specific clinical abilities

  • Ability to formulate assessments and plans
  • Skill in presenting patients succinctly
  • Understanding of basic internal medicine, surgery, and emergency principles
  • Efficient note-writing and documentation

• Work ethic and reliability

  • Punctuality, ownership of tasks, follow-through
  • Willingness to help the team
  • Ability to stay calm and productive when the service is busy

• Professionalism and communication

  • Respectful interactions with nurses, staff, and patients
  • Cultural humility, especially important for IMGs
  • English language proficiency in both spoken and written communication

• Comparative statements

  • “Among the top 10% of students I have worked with in the last five years”
  • “Comparable to our U.S. graduating medical students”
  • These comparative statements are powerful, especially for an IMG.

• Clear endorsement

  • “I give my highest recommendation without reservation.”
  • “I would be delighted to have them as a resident in our own program.”

These phrases signal to a TY program director that the writer is comfortable putting their reputation behind you.

What’s Unique for Transitional Year?

Transitional Year is often broad-based and inpatient-heavy, with rotations in internal medicine, emergency medicine, general surgery, and electives. Therefore, LORs that are especially helpful tend to:

• Highlight adaptability across multiple disciplines
• Emphasize teamwork on busy inpatient services
• Describe performance in general medicine, emergency, or surgery settings
• Show you can handle cross-cover and night-float responsibilities

For example, a strong TY-oriented comment might be:

“During her internal medicine sub-internship, Dr. X comfortably managed a census of 8–10 patients, adjusted plans after overnight events, and communicated plans clearly to nursing staff. She would transition seamlessly into a transitional year residency.”

Such detail is far more convincing than generic praise like, “He was a pleasure to work with and will be an asset to any program.”

Who to Ask for Letters: Strategic Choices for IMGs Targeting Transitional Year

Understanding who to ask for letters is critical. A common IMG mistake is focusing on “big-name” writers who barely know them, instead of supervisors who can write detailed, meaningful letters.

Priority Order for TY Applicants

For an IMG residency guide focused on Transitional Year, a strong portfolio of letters ideally includes:

1. U.S. Clinical Experience (USCE) Letters in Core Clinical Fields

   • Internal Medicine (high priority)
   • Inpatient Family Medicine (if structured like IM)
   • General Surgery or Surgical Subspecialties
   • Emergency Medicine (very valuable for TY, if available)

2. Letters from Academic Settings

   • University-affiliated teaching hospitals carry more weight
   • Community hospitals with residency programs are also strong

3. Supervisors Who Directly Observed You

   • Attendings who saw you daily on rounds
   • Senior faculty or site directors who reviewed your work closely

Who to Ask for Letters (in Practice)

Below is a practical guide on who to ask for letters and why:

• Attending physicians from U.S. inpatient rotations

  • Best option for most IMGs pursuing a TY program
  • They can comment on your clinical skills in the U.S. system, a huge plus

• Program directors or associate program directors where you rotated

  • Very strong if they know you personally
  • They often understand exactly what other PDs look for

• Clinical clerkship directors or department heads who supervised you

  • Helpful if they directly observed your performance
  • Title plus detailed observation is more valuable than title alone

• Research mentors (only if clinically relevant)

  • Use mainly as an additional or fourth letter
  • Works best when they can speak about your reliability, communication, and teamwork—not only research output

Who Not to Prioritize

• Letters from:
  • Non-clinical supervisors (unless for an extra letter)
  • Family friends or distant connections
  • Very senior professors who barely know you
  • Non-U.S. faculty with generic text (unless strengthened by specifics)

These may still be used to fill a gap, especially if you lack USCE, but should not be the backbone of your application.

Balancing U.S. and Home-Country Letters for IMGs

If you are an international medical graduate with limited U.S. experience, aim for:

• At least 2 U.S. clinical letters from IM, FM, EM, or surgery
• 1–2 strong home-country letters that:
  • Highlight your responsibilities (e.g., intern year, house officer work)
  • Emphasize your readiness to function at the PGY-1 level
  • Provide detailed examples of your clinical thinking and independence

Home-country letters can be powerful if they portray you as someone already functioning at or near internship level, especially in busy public hospitals.

How to Get Strong LOR as an IMG: Step-by-Step Strategy

Understanding how to get strong LOR matters as much as selecting the right letter writers. You must deliberately set yourself up for strong, personalized letters.

Step 1: Perform Intentionally During Rotations

From day one of any rotation (U.S. or international), act as if the attending might one day write your letter:

• Arrive early and be prepared
• Know your patients thoroughly
• Take ownership: follow up on labs, imaging, and consults
• Communicate clearly, especially with nursing staff
• Ask for feedback and show visible improvement

Program directors recognize when a letter is based on brief interactions versus sustained performance. Detailed comments only appear when you’ve truly engaged with the rotation.

Example: Instead of passively presenting cases, you:

• Volunteer to give a brief teaching presentation
• Keep a meticulous patient list
• Call consultants after discussing with your resident These actions give attendings concrete material to describe.

Step 2: Signal Early That You Will Need a Letter

By the middle of a rotation, let your attending know you are an IMG hoping to apply to a transitional year residency and that you value their feedback. For example:

“Dr. Smith, I’m planning to apply for a Transitional Year residency as an international medical graduate. I really value your teaching and feedback. If, by the end of this rotation, you feel you know my work well enough, I would be honored to ask you for a letter of recommendation.”

This does two things:

• It prompts the attending to pay closer attention to your performance
• It shows maturity and planning, traits that attendings appreciate

Step 3: Ask the Right Question at the Right Time

When it’s time to ask, framing matters. Do not ask:

• “Can you write me a letter?”
  Instead, ask:

• “Do you feel you know my work well enough to write a strong letter of recommendation for my Transitional Year residency applications?”

This gives them an “escape hatch.” If they say yes, they are more likely to write a supportive letter; if they hesitate, you can seek another writer.

Step 4: Provide a Helpful Letter Packet

Once they agree, make it easy to write a strong LOR:

Include:

• Current CV
• Personal statement (even if in draft form)
• ERAS photo (optional but sometimes appreciated)
• A brief “LOR support document” with:
  • Your full name as it appears in ERAS
  • Your AAMC/ERAS ID
  • Your specific goals (e.g., “seeking Transitional Year with future plans in Radiology”)
  • A 1-page summary of important cases or contributions from that rotation (e.g., “managed a patient with septic shock; led family meeting; presented on CHF management”)

You are not writing their letter for them; you are reminding them of situations they already observed so they can include rich examples.

Step 5: Clarify Logistics and Timeline

Be respectful and specific:

• Give a clear deadline: 2–4 weeks before ERAS opening or program deadlines
• Gently confirm how they prefer reminders (email is usually best)
• Ask whether they plan to upload via ERAS directly

Example email after verbal agreement:

“Dear Dr. Smith,
Thank you again for agreeing to write a strong letter of recommendation for my Transitional Year residency applications. I’ve attached my CV and personal statement, as well as a brief summary of my work during the rotation. My ERAS ID is XXXXXXXX. I plan to certify and submit my application by September 15, so if possible, it would be very helpful to have the letter uploaded by September 1.
Please let me know if I can provide any additional information.
Sincerely,
[Your Name]”

Translating Strong Letters into a Competitive TY Application

You not only need good letters, you need them aligned with your Transitional Year goals and the rest of your application.

How Many Letters Do TY Programs Expect?

Most Transitional Year programs:

• Accept up to 4 letters via ERAS
• Require 3 letters minimum (some count the MSPE separately)

For an IMG pursuing a TY program, a strong combination might be:

1. U.S. Internal Medicine or Family Medicine inpatient letter
2. U.S. Surgery or Emergency Medicine letter
3. Home-country letter documenting intern/house officer performance or advanced student responsibilities
4. Optional: Research or specialty-focused letter (e.g., radiology, anesthesia) if your career goal is clear and the writer knows you very well

Crafting a Coherent Story Across Letters

Your letters should reinforce a consistent narrative:

• You are reliable, teachable, and safe for a PGY-1 role
• You function well on busy inpatient services
• You communicate effectively with a diverse team
• You have a clear plan (even if you’re exploring specialties, show intentionality)

For example, if:

• Your personal statement says you plan to pursue radiology after a TY
• Your letters describe strong clinical reasoning, attention to detail, and professionalism The whole application feels aligned.

If instead:

• You say you want surgery
• But your best letter is non-clinical, and your clinical letters are generic Your application appears weaker and less cohesive.

Addressing Common IMG Concerns in Letters

1. Visa Issues
Letters cannot fix visa limitations, but they can reassure programs that:

• You understand and follow institutional policies
• You adapt quickly to new systems and regulations

2. Gaps in Training or Graduation Year
A good letter can mitigate gaps by emphasizing:

• Continued clinical engagement
• Ongoing medical education (courses, CME, observerships)
• Professionalism and motivation despite challenges

3. Language and Communication
For an international medical graduate, explicit comments about communication are helpful:

• “Her spoken and written English are excellent.”
• “He communicates clearly and is easily understood by patients and staff.”

Program directors reading many IMG applications pay attention to this.

Common Mistakes IMGs Make with TY Letters of Recommendation (and How to Avoid Them)

Mistake 1: Choosing “Famous” Over “Familiar”

Asking the department chair you met briefly versus the attending who worked with you daily is usually a bad trade.

Avoid this by:
Prioritizing writers who supervised you closely and can describe your work with specifics—not just your name on a roster.

Mistake 2: Last-Minute Requests

Rushed letters are often generic.

Avoid this by:

• Identifying potential letter writers months in advance
• Asking 4–6 weeks before your desired upload date
• Politely reminding them 1–2 weeks before the deadline

Mistake 3: Not Customizing for Transitional Year

Using only highly specialized letters (e.g., pure research, subspecialty outpatient clinics) without at least 1–2 robust inpatient generalist letters weakens a TY application.

Avoid this by:

• Ensuring at least two letters clearly speak to your inpatient and generalist skills
• Asking writers to highlight aspects relevant to a Transitional Year (teamwork, adaptability, cross-cover capacity)

Mistake 4: Ignoring Home-Country Opportunities

Some IMGs assume only U.S. letters matter and miss out on strong endorsements from home-country supervisors who know them deeply.

Avoid this by:

• Securing at least one detailed letter from a home-country attending or program director who oversaw your clinical work
• Asking them to:
  • Quantify your workload (number of admissions, calls, etc.)
  • Compare you to peers
  • Comment on your ability to function at intern level

Mistake 5: Never Discussing the Letter Content

You are not allowed to write or edit your own letters, but you can guide your writer by sharing:

• Your goals (Transitional Year, future specialty)
• Your key strengths and examples
• Areas you’ve improved during the rotation

This is not unethical; it is professional preparation.

FAQ: Letters of Recommendation for IMG Transitional Year Applicants

1. How many U.S. letters do I really need as an international medical graduate applying to a TY program?

Ideally, at least two U.S. clinical letters from inpatient rotations in internal medicine, family medicine, surgery, or emergency medicine. If you have more U.S. rotations, select the strongest and most detailed letters. The remainder can come from home-country supervisors who know you well and can comment on your readiness for PGY-1 responsibilities.

2. Is a letter from a famous professor better than one from a community attending who knows me well?

Usually no. For Transitional Year programs, a detailed letter from a community attending who worked closely with you is far more valuable than a brief, generic letter from a famous professor who barely interacted with you. Program directors care more about demonstrated reliability and performance than about name recognition alone.

3. Should my letters be addressed to Transitional Year specifically, or can they be generic?

It’s fine if letters are not TY-only, but they should at least emphasize skills highly relevant to Transitional Year: inpatient care, cross-cover, communication, teamwork, and adaptability. When you request the letter, explain that you are applying mainly to Transitional Year positions and advanced specialties so the writer can phrase their comments appropriately.

4. What if my best letters are from non-U.S. rotations—will that hurt my chances?

Not necessarily. Strong, detailed non-U.S. letters can still be very helpful, especially if they show you already functioning at intern level in a high-volume setting. However, for an IMG applying to U.S. Transitional Year programs, try to have at least one or two U.S. clinical letters to demonstrate your ability to function within the U.S. healthcare system. If that’s not possible, compensate with:

• Clear USMLE performance
• Strong communication skills demonstrated in interviews
• Well-structured, highly specific home-country LORs

---

As an international medical graduate pursuing a Transitional Year residency, you cannot control everything in the match process—but you can deliberately shape the quality of your letters of recommendation. By choosing the right writers, asking thoughtfully, and giving them the tools to advocate for you, your LORs can become one of the strongest parts of your application.
