US Clinical Experience for IMGs: Observerships, Externships and How to Get Them

If you ask US residency program directors what IMGs are most often missing, many will give the same answer: US clinical experience, usually called USCE. Many programs require it, and most strongly prefer it. Just as important, USCE is how you earn US letters of recommendation, one of the strongest parts of an IMG application.

This guide explains the different types of USCE, what each is worth, what it costs, and how to find a position.

Last updated: October 2026. Programs, fees and eligibility rules change, so always check each hospital’s official website before you apply or pay.

Why US clinical experience matters

It shows you can work in the US system: electronic records, team-based care, US patient communication and documentation.
It gives you US letters of recommendation. Letters from US physicians who saw you work carry much more weight than letters from home.
Many programs list it as a requirement. Some ask for a minimum number of months, and some only accept hands-on experience. Check each program’s website or FREIDA listing.
It fills the gap since graduation. Recent clinical activity helps if you graduated several years ago.

The main types of USCE

1. Observership (no hands-on)

You shadow a physician or team: rounds, clinic, procedures and teaching conferences. You do not examine patients, write notes or place orders.

Who can do it: graduates and students; usually on a B-1/B-2 visitor visa.
Typical length: 2 to 4 weeks per rotation, often combined into 1 to 3 months.
Typical cost: from free to about $500 to $2,000+ per month, plus travel and housing.
Value: the lowest of the three types, but still useful, especially for getting a US letter.

2. Externship (hands-on)

You take part in patient care under supervision: taking histories, examining patients, presenting cases and sometimes writing notes.

Who can do it: mostly current medical students. Hands-on positions for graduates are limited and depend on the hospital and state rules.
Value: much higher than an observership, because your letter can describe your actual clinical skills.

3. Clinical electives for students (hands-on)

If you are still a medical student, you can apply for visiting student electives (sub-internships) at US medical schools, many through the AAMC’s VSLO system. These are the most valued type of USCE, because they are graded rotations at teaching hospitals.

Other useful US experience

Research positions at US universities, often paired with clinic time.
Clinical jobs such as clinical research coordinator or medical assistant. They are not USCE in the strict sense, but they show US healthcare experience and can lead to letters.

Important: read the eligibility rules

Big-name hospitals often have formal observership programs, but read the rules carefully. For example, Cleveland Clinic’s international physician observership costs $500 for one month, but it is designed for practicing physicians abroad and does not accept applicants who are seeking US residency. Many famous centers have similar rules.

For residency applicants, university-affiliated community hospitals and programs with many IMG residents are often more realistic, and their letters carry real weight.

How to find a position

Search hospital websites for “observership”, “international visitor” or “visiting physician” in the departments you want, especially internal medicine and family medicine.
Use your network. Senior graduates of your medical school, friends in US residency, and IMG groups on Facebook are the best sources. Many positions are never advertised.
Email physicians directly. Send a short, polite email with your CV, USMLE scores and the dates you are available. Many IMGs get their first observership this way.
Look at programs that train many IMGs. They understand your background and often welcome observers.
Plan your paperwork early. Expect to need your CV, USMLE transcript, ECFMG status, immunization records, a background check, health insurance and a visitor visa.

Beware of expensive “USCE” agencies

Some companies charge thousands of dollars to place IMGs in observerships or “externships”. Some are legitimate; others offer little real value. Before you pay:

Ask exactly which hospital and supervising physician you will work with.
Ask whether the experience is hands-on or observation only, and whether it is allowed on your visa.
Ask if a letter of recommendation is likely, and from whom.
Talk to past participants, not only the testimonials on their website.

How to get a strong letter

Arrive early, stay late and read about every patient you see.
Ask good questions and offer to help with tasks you are allowed to do.
Spend at least 2 to 4 weeks with the same attending so they know you well.
Ask for the letter near the end of the rotation, and give them your CV and a short summary of what you did together.
Ask your letter writers to upload their letters directly to ERAS through the Letter of Recommendation Portal.

Be honest in your application

On ERAS, describe exactly what you did. Don’t call an observership “hands-on” or an “externship” if it wasn’t. Program directors know the difference, and honesty protects your reputation.

My advice from experience

Start USCE early, ideally while studying for Step 2 CK, so your letters are ready before ERAS opens in June.
Quality beats quantity. Two strong US letters from physicians who know you are worth more than many short observerships.
Choose USCE in the specialty you are applying to, or in internal medicine if you are applying broadly.
Stay in touch with the doctors you work with. Many IMGs get interviews through these relationships.
