Ultimate Guide to Residency Letters of Recommendation for US Citizen IMGs

Understanding Letters of Recommendation for US Citizen IMGs in Clinical Informatics

For a US citizen IMG (American studying abroad) targeting Clinical Informatics, letters of recommendation (LORs) can make or break your application. Program directors rely heavily on LORs to understand not only your clinical skills, but also your potential to thrive in health IT training and eventually a clinical informatics fellowship.

Unlike traditional specialties, Clinical Informatics lives at the intersection of patient care, data, and systems design. Strong residency letters of recommendation must therefore address both your clinical competencies and your informatics mindset: your ability to think in workflows, your comfort with technology, and your skill at collaborating across teams (IT, nursing, administration, and physicians).

This article will walk you through:

• What kind of LORs are most impactful for a US citizen IMG applying with an eye toward Clinical Informatics
• Who to ask for letters (and who not to)
• How to get strong LORs that highlight both clinical and informatics potential
• How to strategically present your letters in ERAS when you’re an American studying abroad
• Common pitfalls and how to avoid them

Throughout, the focus is on helping you reach your ultimate goal: building a credible pathway from residency into a clinical informatics fellowship or a career in health IT.

What Makes an LOR Powerful for Clinical Informatics–Bound Applicants?

Program directors in core clinical specialties (IM, FM, EM, Peds, etc.) generally want three things from a letter:

1. Evidence you can practice safe, effective medicine
2. Evidence you’re reliable and professional
3. Evidence you will be easy to train and work with

For applicants interested in Clinical Informatics, there are two additional layers:

4. Evidence you understand and value systems-level thinking, data, and technology
5. Evidence you can communicate and collaborate across disciplines (clinicians, IT, leadership)

Core Components of a Strong LOR

When you think about how to get strong LORs, focus on the specific content that will matter for informatics:

• Concrete examples: “Dr. X led a mini-QI project to reduce order-entry errors…” is far more powerful than “Dr. X is interested in informatics.”
• Comparative statements: Phrases like “among the top 10% of students I have supervised in the last 5 years” carry heavy weight.
• Clinical competence plus systems awareness: You want letters that show you are solid clinically and that you see the bigger picture of workflows, data, and safety.
• Communication and leadership: Informatics lives on committees and project teams; letters that highlight your work with nurses, IT, and other stakeholders are golden.

Informatics-Specific Strengths to Highlight

Advise your letter writers (tactfully) to mention:

• Comfort with EHRs and digital tools (CPOE, dashboards, CDS tools)
• Participation in any QI, patient safety, or data-driven projects
• Experience with clinical decision support, documentation improvement, or order set optimization
• Ability to translate between frontline clinicians and technical staff
• Curiosity about workflows, usability, and systems design

For a US citizen IMG, these specifics can help counteract biases about training quality abroad and demonstrate that you’re already thinking like a future informatician.

Who to Ask for Letters: Strategic Choices for US Citizen IMGs

Many US citizen IMGs know they need LORs but are unsure who to ask for letters, especially if much of their clinical training occurred outside the US. For Clinical Informatics–oriented applicants, the “who” is especially important.

Priority 1: US Clinical Supervisors in Your Intended Core Specialty

Residency programs still recruit primarily into core specialties, not directly into clinical informatics. Your first priority is letters from US-based attendings who supervised you in your target residency specialty—usually:

• Internal Medicine
• Family Medicine
• Pediatrics
• Emergency Medicine
• (Occasionally) Psychiatry, Pathology, or other fields

Ideal writers:

• Core faculty, clerkship directors, or program leadership at US hospitals where you did electives or observerships
• Hospitalists or attendings who can comment on:
  • Your clinical reasoning
  • Work ethic and reliability
  • Patient communication
  • Teamwork and professionalism

As a US citizen IMG, US-based clinical letters help reassure programs that you understand the US healthcare system, EMR workflows, documentation standards, and patient expectations.

Priority 2: Mentors in Clinical Informatics or Health IT

If you’ve worked with:

• A CMIO (Chief Medical Information Officer) or associate CMIO
• A clinical informatics–trained attending physician
• A faculty member involved in EHR implementation, CDS design, or health IT training
• A leader of a QI or patient safety program with a strong data component

…their letter can be extremely powerful as one of your four ERAS letters, even if your target program is “just” IM or FM. This type of letter signals your authentic interest in informatics and demonstrates that someone already working in the field sees your potential.

Priority 3: Research Supervisors (Especially with an Informatics Angle)

If you have research in:

• Clinical decision support
• EHR usability or workflow studies
• Predictive analytics or machine learning in healthcare
• Population health, data registries, or outcomes research
• Implementation science or digital health interventions

Then a research mentor’s letter can show:

• Your ability to handle complex projects
• Comfort with data and analysis
• Persistence and intellectual curiosity
• Strong academic writing, presentation, and collaboration skills

Make sure the research letter also mentions your interpersonal strengths and work ethic, not just your technical skills.

Priority 4: Non-Clinical but Informatics-Relevant Professionals

In some cases, especially if you have a gap between graduation and application, you may have worked:

• As a clinical data analyst, health IT associate, or EHR trainer
• On a digital health startup
• In a hospital IT department

Letters from non-physician supervisors (e.g., an IT director, data science lead, or product manager) can be useful as a supplemental perspective, particularly to document your health IT training and real-world informatics exposure.

However, you should not replace core clinical letters with these. Use them as a fourth letter when allowed or as evidence of sustained informatics involvement.

Who Not to Rely On for Your Main Letters

• Very senior people who barely know you (e.g., Dean, CEO, hospital president)
• Letters from non-US settings only, if you have access to US clinical experiences—US letters outweigh foreign ones for residency
• Letters from family friends or informal observers
• Generic “character reference” letters that say nothing about your clinical or project-based work

For a US citizen IMG, your letter mix should ideally look like:

• 2–3 US-based clinical letters in your chosen core specialty
• 1 letter with a clear clinical informatics / health IT / QI / data focus (can be clinical or research-based)

How to Get Strong LORs as a US Citizen IMG with Informatics Interests

Knowing who to ask is only half the battle; the other half is earning and supporting strong letters.

Step 1: Plan Early and Align Your Experiences

From the start of your US clinical experiences (or even before):

• Seek rotations in tech-forward environments: Academic centers, hospitals undergoing EHR optimization, or sites with strong QI culture.
• Ask early about informatics opportunities: Can you attend any IT or QI meetings? Help with a small data project? Shadow a CMIO for a day?
• Signal your interests clearly: Without overdoing it, let attendings know you’re interested in Clinical Informatics and want to understand both patient care and systems.

This alignment makes it much easier for them to later write an LOR that naturally connects your clinical performance to your future informatics career.

Step 2: Excel on the Rotation (Clinically and Professionally)

Even if your end goal is a clinical informatics fellowship, residents and fellows must first be strong clinicians. Your letter writers will focus on:

• Clinical reasoning: Clear presentations, prioritized assessments, evidence-based plans
• Reliability: Showing up early, following through on tasks, updating teams, responding to feedback
• Team skills: Respectful communication with nurses, pharmacists, social workers, and IT staff
• Documentation and EHR use: Thoughtful notes, safe order entry, attention to detail

As an American studying abroad, you’re often under extra scrutiny during US rotations. Use that to your advantage as motivation to be meticulous and proactive.

Step 3: Build a Genuine Relationship

Letters are strongest when the writer knows you well and cares about your success.

• Ask for feedback: “I’m very interested in improving—are there specific areas you think I should work on?”
• Show growth: Act on their feedback and let them see the changes.
• Engage beyond the basics: Ask thoughtful questions about cases, systems issues, and informatics-related challenges they see in daily work.

If there is an informatics-minded attending or a faculty member involved in QI, make a conscious effort to connect: ask about their projects or committees, and offer to help in small ways.

Step 4: Ask for the Letter the Right Way

When it’s time, don’t just ask for “a letter.” Instead, ask:

“Would you be comfortable writing a strong letter of recommendation for my residency applications, highlighting both my clinical performance on your rotation and my interest and potential in Clinical Informatics?”

This phrasing matters because:

• It gives them an “out” if they can’t write you a strong letter.
• It explicitly cues them to address your informatics interest.

If they hesitate or appear lukewarm, you are better off not using that letter.

Step 5: Provide a Helpful LOR Packet

To help your writer produce a focused, detailed letter, share a concise packet:

• Updated CV
• Personal statement (or at least a draft) emphasizing your journey as a US citizen IMG and interest in informatics
• A 1-page “LOR guide” you create for them, including:
  • A few bullet points of cases or projects you worked on together
  • Highlights you hope they might mention (e.g., QI project, teaching session, or EHR workflow suggestions you made)
  • Your specific target core specialty and your long-term interest in a Clinical Informatics fellowship
• ERAS letter submission instructions and deadlines

Be polite and clear that these are just to jog their memory; they should feel free to write in their own voice and focus on what they sincerely believe.

Tailoring LOR Content for a Clinical Informatics–Oriented Application

You don’t write the letter yourself, but you can influence what gets emphasized by what you demonstrate and what you share with the writer.

Key Themes Your Letters Should Address

1. Clinical Competence and Safety

   • Clear, organized presentations
   • Sound judgment in common inpatient/outpatient problems
   • Responsiveness to supervision and feedback

2. Systems and Workflow Awareness

   Examples your writer might mention:

   • You noticed redundant documentation steps and proposed a safer, more efficient approach.
   • You recognized an EHR alert that was creating “click fatigue” and suggested a tweak that improved adherence.
   • You contributed to a small QI project related to handoffs, order sets, or discharge summaries.

3. Data-Driven Thinking

   • Comfort discussing trends, dashboards, or metrics (e.g., readmission rates, lab turnaround times)
   • Interest in how clinical decisions are influenced by data and CDS tools
   • Experience interpreting basic run charts, control charts, or audit reports

4. Interdisciplinary Collaboration

   • Working closely with nursing, pharmacy, case management, or IT
   • Helping bridge misunderstandings between frontline staff and technical teams
   • Serving as a liaison or “superuser” for an EHR tool during your rotation, if applicable

5. Professionalism and Long-Term Potential

   • Reliability, integrity, and respect
   • Emotional intelligence and resilience under stress
   • Explicit support for your trajectory: “I believe Dr. X will excel in residency and subsequently be a strong candidate for a clinical informatics fellowship.”

Example: What a Strong Paragraph Might Look Like

To help you visualize what a robust, informatics-friendly paragraph in a letter may look like:

“During our internal medicine sub-internship, Dr. Smith distinguished herself not only through strong clinical reasoning but also through her keen interest in systems-level improvement. She identified that our EHR discharge medication reconciliation screen was contributing to recurrent errors in anticoagulant dosing. On her own initiative, she collected data on ten recent discharges, analyzed discrepancies, and presented her findings at our team huddle. She proposed a simple template change and additional CDS prompt which we are now piloting. This type of careful observation, data-driven problem-solving, and collaborative communication with our IT liaison is exactly what I would expect from a future leader in Clinical Informatics.”

If your experiences lend themselves to this kind of narrative, your letters will stand out.

Presenting Your Letters in ERAS and Positioning for Future Informatics Training

Once you have your letters, you still need to think strategically about how they appear in your residency application—and how they set you up for a future clinical informatics fellowship or health IT career.

Letter Mix Strategy

For most core specialties, a strong mix for a US citizen IMG with informatics interests is:

• 2–3 US specialty-specific clinical letters

  • Example: Internal Medicine letters for IM residency
  • At least one from core faculty or program leadership, if possible

• 1 informatics / QI / research–oriented letter

  • Can be from:
    • An informatics-trained physician
    • A QI director or physician leader deeply involved in EHR/workflow improvements
    • A research mentor with informatics or data-heavy projects

If a program allows more than four letters to be stored but only three or four to be assigned per program, you can tailor which informatics-focused letter you send to which program (e.g., academic centers with known health IT strength).

Addressing the US Citizen IMG Context

Your letters can (and should) help address typical concerns around IMGs:

• Adaptation to US healthcare system
  “Despite training at an international medical school, Dr. X adapted quickly to US clinical workflows and documentation standards.”

• Communication with patients and staff
  “Her communication with patients—many of whom had limited health literacy—was clear and compassionate, and she worked very effectively with nurses and ancillary staff.”

• Readiness for residency
  “I have no reservations about her ability to transition smoothly into US residency training.”

If your writer already knows that you are a US citizen IMG, it’s reasonable to mention in your LOR guide that acknowledging your smooth transition into US healthcare could be helpful.

Connecting LORs to Long-Term Informatics Goals

Even if programs are not specifically recruiting for a clinical informatics fellowship track, they often value residents who:

• Help optimize EHR workflows
• Participate in QI and safety initiatives
• Are comfortable interacting with IT and data teams

Letters that frame you as someone who will add value in these areas can impress program directors—even those who don’t know much about the formal clinical informatics subspecialty.

Later, when you apply for a clinical informatics fellowship, these same LORs (and newer ones from residency) will form a coherent story: you’ve consistently pursued and excelled in informatics-related work.

Frequently Asked Questions (FAQ)

1. How many informatics-focused letters should I have as a US citizen IMG?

Aim for one well-targeted informatics-focused letter within a set of 3–4 total LORs. Program directors still prioritize clinical letters in the core specialty you’re applying to (IM, FM, etc.). One strong, informatics-oriented letter—especially from someone active in health IT or QI—is usually sufficient to signal your long-term interest without overshadowing your clinical readiness.

2. What if my medical school is abroad and all my strong clinical letters are non-US?

As an American studying abroad, try hard to secure at least one or two US-based clinical letters from electives, sub-internships, or observational roles where you had meaningful clinical involvement. Non-US letters can still be valuable, but US programs strongly prefer evidence that you have functioned in the US system. If your US contacts are limited, consider:

• US-based research positions with clinical integration
• Longer observerships and structured experiences where you can meaningfully contribute
• Networking with faculty involved in health IT training who might involve you in QI or systems-based projects

3. Can a non-physician (like an IT manager or data scientist) write a primary LOR for residency?

They can write an additional letter but should not replace your core clinical letters from physicians. A non-physician supervisor can provide a valuable perspective on your health IT training, data skills, or project management abilities. However, residency program directors must see strong evidence of your clinical performance and professionalism from physicians who have supervised your patient care.

4. Is it appropriate to mention my goal of pursuing a clinical informatics fellowship in my letters?

Yes, and it can be helpful. Your letter writers can briefly mention that you are interested in a future clinical informatics fellowship or career in health IT. The key is balance: the letter must still primarily emphasize your readiness for the core clinical residency, while framing your informatics aspirations as a strength that will benefit the program (e.g., through QI, EHR optimization, and data-driven care).
