Mastering Letters of Recommendation for Non-US Citizen IMGs in Prelim Medicine

Understanding the Role of Letters of Recommendation in a Preliminary Medicine Year

For a non-US citizen IMG, letters of recommendation (LORs) can make or break your application to a Preliminary Medicine (prelim IM) residency. Program directors often rely heavily on LORs to answer a critical question:

“Can this foreign national medical graduate function safely and effectively in a US clinical environment as an intern on day one?”

Because many non-US citizen IMGs come from different medical systems, LORs become the “translation tool” that shows US programs how your skills, professionalism, and work ethic compare with their expectations. In a competitive environment—especially for prelim IM positions that often feed into advanced specialties (neurology, anesthesiology, radiology, etc.)—strong letters can dramatically increase your chances of interviews and ranking.

This article will walk you through, step-by-step:

• How program directors actually use LORs in evaluating non-US citizen IMGs
• How many letters you need, and which types are strongest for a preliminary medicine year
• Who to ask for letters (and who not to)
• How to get strong LOR from US physicians and from your home country
• Practical scripts and timelines tailored to foreign national medical graduates
• Common pitfalls and how to avoid them

Throughout, we’ll focus specifically on preliminary medicine, but almost all principles apply to categorical internal medicine as well.

How Important Are LORs for a Non‑US Citizen IMG in Prelim IM?

Why LORs Matter More for Foreign National Medical Graduates

As a non‑US citizen IMG, you face several additional layers of scrutiny:

• Limited or no US clinical experience (USCE)
• Different grading systems and medical curricula
• Possible gaps after graduation
• Visa requirements (J-1 or H-1B sponsorship)

Program directors cannot directly compare your home-institution clerkship grades with those of US students. Instead, they depend on LORs—especially from US-based physicians—to gauge:

• Your clinical reasoning and bedside skills
• Your ability to adapt to US hospital culture and documentation
• Your English communication (spoken and written)
• Your professionalism, reliability, and teamwork
• Whether you can handle intern-level responsibility in a busy prelim IM year

In many PD surveys, LORs rank among the top factors in granting interviews, particularly when evaluating IMGs.

Special Considerations for Prelim IM

Preliminary medicine year programs want residents who:

• Learn quickly and require minimal supervision after initial orientation
• Can manage heavy inpatient workloads and cross-cover safely
• Are dependable, punctual, and organized
• Work well with multidisciplinary teams
• Do not create interpersonal or professionalism problems

For this reason, your best letters for a preliminary medicine year are:

• Inpatient internal medicine LORs from US academic hospitals
• Subspecialty IM LORs where you rotated in a US setting (e.g., cardiology, nephrology, hospitalist service)
• Current-year letters that reflect your recent performance

If you’re planning advanced specialties (neurology, radiology, anesthesiology, etc.), strong prelim IM letters still matter greatly, because many advanced programs want to be sure you will succeed in your intern year.

How Many Letters You Need—and Which Types Are Best

Basic Numbers for ERAS

For ERAS:

• You can assign up to 4 letters per application
• Most internal medicine and prelim IM programs expect 3 letters minimum, and many like to see 3–4
• As a non‑US citizen IMG, having at least 2 US-based clinical LORs is strongly recommended, if at all possible

Ideal Letter Mix for a Non‑US Citizen IMG Applying to Prelim Medicine

Target mix:

1. US inpatient internal medicine or hospitalist LOR (core)

   • Most valuable letter for a prelim IM application
   • Shows how you perform on wards and night shifts
   • Demonstrates your ability to handle typical prelim intern tasks

2. Second US-based LOR in internal medicine (or IM subspecialty) (core)

   • Could be from cardiology, GI, nephrology, critical care, etc.
   • Especially strong if the attending comments on your overall “intern-level” readiness

3. Home-country internal medicine or senior medicine faculty LOR (supporting)

   • Demonstrates long-term observation and continuity
   • Helpful if they can speak to sustained performance, leadership, or academic achievements
   • Better if from a well-known institution or chair / program director

4. Optional: Advanced specialty letter (if applying for a linked advanced spot)

   • For example, neurology, radiology, anesthesiology
   • Should emphasize clinical reasoning and potential in that specialty, but still mention that you will excel in a demanding preliminary medicine year

If you can only submit 3 letters, prioritize:

1. US inpatient IM/hospitalist letter
2. Second US IM/subspecialty letter
3. Best long-term home-country IM or senior faculty letter

What If You Have No US Clinical Experience?

Many non‑US citizen IMGs are unable to secure USCE before applying, due to cost, visa, or timing. In that case:

• Aim for:

  1. Internal medicine department chair or program director from your home institution
  2. A senior faculty member who supervised you extensively in medicine or surgery
  3. A research mentor (ideally with some clinical exposure) or chief of service

• Ask your home-country letter writers to:

  • Explicitly comment on how you might perform in a US training environment
  • Emphasize adaptability, work ethic, and communication in English
  • Highlight any international exposure, conferences, or observerships

While this is not as strong as having US letters, well-written, detailed home-country letters are still much better than generic or template-style LORs.

Who to Ask for Letters—and Who Not To

Many IMGs focus on whether the potential writer is “famous.” For a foreign national medical graduate, that often matters less than how well they know you and how specifically they can describe your work.

Who to Ask for Letters (Priority List)

1. US Internal Medicine Attendings Who Directly Supervised You Clinically
   Best sources for prelim IM:

   • Inpatient ward attendings
   • Hospitalist attendings
   • ICU attendings (if you had meaningful responsibility)
   • Subspecialty IM attendings (cardiology, nephrology, etc.), if they observed your clinical work

   These letters are powerful because they can say:

   • “I saw this applicant manage multiple patients per day”
   • “They presented clearly, wrote notes, and followed up results reliably”
   • “They functioned close to an intern level”

2. Internal Medicine Program Directors or Associate Program Directors
   Very strong if:

   • They directly supervised you (e.g., on service, in clinic, or in a sub-internship)
   • Or they reviewed your performance closely and know you beyond just a short observership

   These letters carry weight because PDs understand exactly what their peers need to know about an applicant.

3. Home-Country Department Chair or Senior Internal Medicine Faculty
   Particularly helpful when:

   • They have known you for years
   • You were involved in multiple rotations, projects, or teaching roles under them
   • They can provide long-term perspective on your professionalism, resilience, and growth

4. Research Mentors With Clinical Interaction
   Useful if:

   • The research is clearly related to internal medicine or your future specialty
   • They also saw you in clinical settings (rounds, case discussions, clinics)
   • They can comment on your reliability, communication, and academic potential

5. Advanced Specialty Faculty (If Applying to a Linked Advanced Position)
   For example, a neurology or radiology attending who:

   • Supervised your clinical elective
   • Can say you will be a strong resident in that field
   • Also affirms you will succeed in a demanding preliminary medicine year

Who Not to Ask (or Use Only as Secondary Letters)

• Short-term observers where you shadowed for only a few days

  • Likely to produce vague, generic letters
  • Programs can tell when the writer barely knows you

• Non-physician professionals (unless uniquely appropriate)

  • Letters from nurses, administrators, or non-clinical supervisors usually carry less weight for clinical performance
  • May be acceptable as a supplemental 4th letter, but not core

• Family members or close personal friends

  • Strong conflict-of-interest concerns
  • Can undermine your professionalism

• Political figures or non-medical dignitaries

  • Even if they are high profile, they cannot comment on your intern-level clinical ability

• Any writer who seems hesitant or lukewarm

  • If you sense hesitation (“I’m very busy,” “I don’t know you that well”), reconsider
  • A neutral or weak letter can hurt more than having fewer letters

How to Evaluate If Someone Can Write You a “Strong” Letter

Before you ask, assess:

• Did they see you work consistently (at least 2–4 weeks)?
• Did you:
  • Present patients regularly?
  • Write notes (or drafts) that they reviewed?
  • Interact with patients and families, not just observe?
• Did they praise your work or give positive feedback during or after the rotation?

If yes, they are likely good candidates.

You can also ask directly:

“Do you feel that you could write me a strong letter of recommendation for a Preliminary Internal Medicine residency position?”

If they hesitate, thank them and move on.

How to Get Strong LOR as a Non‑US Citizen IMG

This is where your strategy matters most. The question is not just who to ask, but how to get strong LOR that truly distinguish you from hundreds of other applicants.

1. Perform Intentionally During Rotations

From day one of any US rotation (elective, observership, externship, sub-internship), behave as if you are already being evaluated for a letter.

Focus on:

• Punctuality and reliability
  • Arrive early, stay until work is done
  • Never disappear without informing your team
• Preparation
  • Read about your patients’ conditions nightly
  • Present with a clear, concise, structured style
• Ownership of tasks
  • Volunteer to follow up labs, imaging, and consults
  • Keep a personal list and update your attending proactively
• Communication
  • Speak clearly and respectfully with patients, staff, and team members
  • Ask thoughtful questions that show you are reading and thinking, not just memorizing
• Professionalism
  • Handle criticism maturely
  • Maintain confidentiality and appropriate boundaries
  • Follow dress codes and institutional policies

Targeted excellence over 2–4 weeks can produce a powerful LOR.

2. Signal Your Interest Early

For a foreign national medical graduate, it helps if the attending understands the stakes:

Within the first week of a US rotation, tell your attending or senior:

“I am a non‑US citizen IMG planning to apply for a Preliminary Medicine residency. I’m very interested in learning how to practice effectively in the US system. I’d be grateful for any feedback on how I can improve and potentially be competitive for residency.”

This does two things:

1. Encourages them to watch you more closely (which helps them write a detailed letter later)
2. Signals your seriousness and transparency

3. Ask for Feedback During the Rotation

Mid-rotation, ask:

“Could I get a few minutes of your feedback on how I’m doing, especially in areas that are important for intern-level performance?”

Listen carefully. Then show measurable improvement. When they later write your LOR, they can mention your responsiveness to feedback—a major plus for prelim IM.

4. Timing and Method: When and How to Ask for the Letter

When to ask:

• Ideally in the final week of the rotation, when your performance is fresh in their mind
• No later than 2–3 months after the rotation ends

Sample script (adapted for non‑US citizen IMG in prelim IM):

“Dr. Smith, I’ve greatly appreciated working with you on this internal medicine service. As you know, I’m a non‑US citizen IMG and will be applying for Preliminary Internal Medicine positions this cycle. Would you feel comfortable writing me a strong letter of recommendation commenting on my clinical abilities, work ethic, and readiness for intern-level responsibilities in the US system?”

If they say yes:

• Confirm how they prefer to receive supporting materials:
  • CV
  • ERAS personal statement (even in draft form)
  • Transcript or MSPE if relevant
  • A bulleted list of patients or cases you worked on with them
• Clarify the timeline (e.g., “ERAS opens for letter uploads in early summer; I hope to have all letters in by [date].”)

5. Provide a Helpful “Brag Sheet” (Without Writing Your Own Letter)

To help your writer produce a strong, specific LOR, send:

• Your CV (with dates, roles, publications, and presentations)
• Draft personal statement, especially if it explains your prelim IM and advanced specialty goals
• Short bullet list (1–2 pages) including:
  • Patients you followed closely
  • Procedures or tasks you performed
  • Examples of when you went “above and beyond”
  • Any feedback they gave you and how you acted on it

For example:

• Managed 4–6 patients daily on general medicine service
• Independently presented new admissions and daily follow-ups
• Identified early signs of sepsis in Mr. X and immediately alerted the team, leading to rapid intervention
• Consistently arrived 30–45 minutes early to pre-review charts and lab results

You are not writing the letter for them; you are simply jogging their memory and giving them concrete material to use.

6. Gentle, Professional Reminders

Busy attendings may forget. A polite reminder is acceptable, especially for a foreign national medical graduate who cannot afford delays.

Timeline for reminders:

• First reminder: 2–3 weeks after initial request
• Second reminder: 2–3 weeks before your self-imposed ERAS completion date

Sample reminder email:

“Dear Dr. Smith,
I hope you are doing well. I wanted to kindly follow up regarding the letter of recommendation you agreed to write for my Preliminary Internal Medicine residency application. ERAS is now open for letter uploads, and I hope to finalize my application by [date]. Please let me know if there is any additional information I can provide.
Sincerely,
[Your Name]”

Remain respectful at all times; do not send reminders too frequently.

Optimizing the Content and Impact of Your LORs

You do not control the exact wording—nor should you—but you can influence what your letters emphasize by the way you present yourself and the information you provide.

Core Elements of a Strong Prelim IM Letter for a Non‑US Citizen IMG

Strong residency letters of recommendation for prelim IM usually include:

1. Context and Duration of Relationship

   • “I supervised Dr. X for 4 weeks on the inpatient internal medicine service at [US Hospital].”

2. Level of Responsibility and Role

   • “He functioned at the level of a sub-intern, taking primary responsibility for 4–5 patients daily.”

3. Clinical Skills and Judgment

   • Quality of history and physical exam
   • Ability to formulate differential diagnoses and management plans
   • Responsiveness to changes in patient status

4. Work Ethic and Reliability

   • Punctuality, follow-through, charting completeness
   • Ownership of tasks and follow-up

5. Communication and Teamwork

   • Interaction with patients, families, nurses, and consulting teams
   • Clarity and conciseness of presentations

6. Professionalism

   • Integrity, honesty, respectfulness
   • Handling feedback and stressful situations

7. Comparison and Ranking

   • “Dr. X ranks in the top 10% of international students I have supervised.”
   • “I would be delighted to have them as a preliminary or categorical medicine resident in our program.”

8. Clear Endorsement

   • “I give Dr. X my strongest recommendation for a Preliminary Internal Medicine residency position.”

If a letter includes these elements with specific examples, it will stand out—even if you are a foreign national medical graduate competing with US graduates.

Should You Waive Your Right to See the Letters?

In ERAS, you can choose to waive or not waive your right to see a letter.

• Strongly recommended: Waive your right
  • Program directors interpret waived letters as more likely to be honest and candid
  • Non-waived letters may raise questions about authenticity

Almost all serious applicants, including US graduates, waive their rights. As a non-US citizen IMG, you should do the same.

Special Issues: Visas, Gaps, and Non‑Traditional Backgrounds

Addressing Visa and Sponsorship Concerns

Residency letters of recommendation are not where you discuss visa type or sponsorship; that belongs in your CV, ERAS application, or communications with programs. However, your letter writers can:

• Mention your adaptability and professionalism in a new healthcare system
• Highlight your ability to communicate effectively in English, both verbally and in documentation
• Emphasize that you integrated quickly into the team despite being a non‑US citizen IMG

This indirectly reassures programs that you can handle the transition, visa logistics aside.

Explaining Gaps and Non‑Clinical Periods

If you have:

• Years since graduation
• Research-only periods
• Personal or family-related gaps

LORs can help by:

• Documenting your current clinical readiness (e.g., from a recent US rotation)
• Showing that you remained academically or clinically engaged
• Providing context for any unconventional career path

You can gently brief your writers about these issues so they can support your narrative, but avoid asking them to “justify” your gaps explicitly.

Frequently Asked Questions (FAQ)

1. How many US letters do I absolutely need as a non‑US citizen IMG applying to a preliminary medicine year?

Aim for at least 2 US clinical LORs if at all possible, ideally from internal medicine or hospitalist attendings. If you can only obtain 1, make sure it is very strong, and pair it with your best home-country letters. Programs understand not all foreign national medical graduates can afford extensive USCE, but US letters significantly improve your credibility and interview chances.

2. Is a famous professor better than someone who knows me well?

For prelim IM, a detailed letter from someone who knows you well is usually more valuable than a brief, generic note from a famous professor. Program directors want concrete evidence of how you function in a clinical team, not just prestigious names. A well-known writer is an added bonus—but only if they can write a specific, enthusiastic letter.

3. Can research mentors write strong residency letters of recommendation for me?

Yes, especially if they are clinicians or if your research was clinically oriented. To be useful for a prelim IM position, the letter must comment on:

• Reliability and work ethic
• Communication skills
• Problem-solving ability
• Professionalism and teamwork

If the mentor never observed you clinically, their letter should be used as a supplemental letter (e.g., a 4th letter) rather than a core one.

4. What if my home-country letters are not in English?

All ERAS letters of recommendation must be uploaded in English. If your writer is not fluent, you can:

• Offer to draft a summary of your work in English for them to adapt
• Suggest that they write in their native language and then work with your institution’s official translation services (if available)

However, the final uploaded letter must be in clear, professional English. Never translate and sign for them; that compromises integrity.

---

Thoughtful planning and intentional performance can turn your letters of recommendation from a vulnerability into a major strength, even as a non‑US citizen IMG applying to a preliminary medicine year. Focus on building genuine relationships with supervisors, seeking feedback, and asking strategically—and your LORs will reflect the intern you are ready to become.
