Watching Isn't Hands-On: What Counts as US Clinical Experience for IMGs (2027)

Published 2 November 2026 · Luke, co-founder of OET BANK and USMLE BANK · 13 min read

Doctors trained abroad hear early that they need "USCE", US clinical experience, and many book the first observership they can find. Residency programs do not all mean the same thing by it. Some count only hands-on work and say plainly that an observership does not qualify. Some want it within the last year or two. Many want a letter from a US physician who supervised you. And once you have graduated, US law generally lets you watch patient care but not take part in it. This article explains the kinds of US clinical experience, who can get which, what programs ask for, the health documents every hospital wants before your first day, and how to judge a program you pay for, as things stand in November 2026.

1. What programs mean by USCE

There is no national definition of US clinical experience. No exam, no ECFMG rule and no Match rule requires it. It matters because programs ask for it, and each program decides what counts. Here is what a few of them say on their own pages:

At the other end, a few programs say US experience is not required at all, though it helps, especially with letters from US physicians. Three patterns repeat. Programs look at what you actually did (hands-on care or watching), at how recent it is, and at who can vouch for you in a letter. Many also limit how long ago you graduated, often to within three to five years. A month of shadowing at a famous hospital can be worth less to these programs than two months of supervised patient care somewhere smaller, if the second one ends with a strong letter.

USCE is also not a substitute for exam results. In a 2025 survey of 222 African international graduates, having US clinical experience was not clearly linked to getting more interviews, while a high Step 2 CK score and passing every Step on the first attempt were. The survey was small and did not separate hands-on work from observerships, but the order of priorities it suggests is a fair one: the exams first, then experience that a US physician can describe.

2. Four kinds of US clinical experience

The line that matters most is the one between a student and a graduate. A student on an elective takes part in patient care as part of a medical education program, under the host's supervision, which state law allows. A graduate who is not yet in a residency has no license and no training permit, so the same work becomes the unlicensed practice of medicine. That is why the best hands-on experience is easiest to get before you graduate.

3. While you are a student: electives

A clinical elective is the most valuable kind of US experience for most programs, and it is open only while you are enrolled. Most US medical schools take visiting students through the AAMC's Visiting Student Learning Opportunities (VSLO) service. Three rules decide whether you can use it:

• Your own school must be a member. The AAMC says VSLO is only accessible to students at participating home institutions, and your school invites you in and releases each application. As of 2 November 2026 its list of home institutions has 332 schools; outside the US they include three in Japan, two in South Korea, two in Taiwan, three in Mexico, one in Spain, four in Egypt, three in Jordan and two in Saudi Arabia.
• Schools outside the US cannot join for now. The AAMC's page for institutions says it is not currently reviewing new applications from institutions outside the United States while it revises its global program.
• The side door has closed. Until recently some students from non-member schools applied as "free movers". Yale's page for international visiting students says that pathway ended in August 2026 and that Yale cannot accept students whose schools do not take part in VSLO.

VSLO itself charges students $15 for each elective they apply to, rising to $18 when the 2027 season opens in February. In the new system for 2027, students get access in mid-January and can submit applications from early February. Hosts open their catalogs at different times, and many ask you to apply four to six months ahead. If your school is not a member, ask your dean's office whether it has an exchange agreement with a US school, and ask each host directly whether it can take you outside VSLO; many, like Yale, cannot.

What hosts ask for

Each host sets its own conditions and fees, on top of VSLO's. Three examples from their current pages:

• Mayo Clinic Alix School of Medicine: applications only through VSLO; international students must have passed Step 1, be in their final year, and, if they were not taught in English, have a TOEFL score of at least 104 within two years. A $350 application fee and health insurance worth at least $50,000.
• Cleveland Clinic: a passing Step 1 score, which it does not waive; final-year students who have finished their core clerkships; English proof by OET or TOEFL, also not waived; a $400 fee for international applicants, covering up to two electives. Students who do not meet these may apply as observers instead.
• Yale School of Medicine: final year, English by TOEFL, IELTS, OET or CAE, and tuition of $4,775 for a four-week elective in 2026–27. Apply six months ahead, and no later than four.

Two things stand out. Step 1 often comes first: hosts like Mayo Clinic and Cleveland Clinic will not look at you until you have passed it. And the cost is mostly the host's, not the AAMC's. Mayo Clinic lists an application fee but no tuition; a four-week elective costs $3,000 at Weill Cornell, $4,775 at Yale, $5,500 at Johns Hopkins and $5,900 at Harvard, before travel and housing. Some of the best-known schools also take international students only from named partner schools: Harvard lists 17, and Johns Hopkins takes students only from schools it has an agreement with.

New York adds a rule of its own. Unless your school has the state's approval for long clerkships, you may do clerkships in New York for no more than 12 weeks in total over two academic years, with a letter of eligibility from the state's education department, and only in subjects in which the hospital has an accredited residency program. Weill Cornell tells the international students it accepts to file with the department.

The visa for an elective

The State Department's Foreign Affairs Manual makes one exception for hands-on clinical work on a visitor visa. A student at a foreign medical school may take an elective clerkship at a US medical school's hospital on a B-1 visa if the hospital pays nothing, the clerkship is an approved part of the student's own curriculum, and it is supervised by faculty. The exception does not cover graduates. Hosts usually send the letter for your visa application after they accept you; Cleveland Clinic, for example, asks for a B-1. If your country is in the Visa Waiver Program, ask the host before travelling on ESTA: some, such as Vanderbilt and Thomas Jefferson University, accept visiting students entering under the program as business visitors, while those that spell it out do not accept tourist status.

4. After you graduate: observerships

Once you have your degree, the AMA puts it simply: international graduates can only apply for an observership, which it describes as strictly shadowing with no hands-on patient contact. State law is where that comes from. Iowa's medical board, for example, wrote it into its rules in May 2025: an international graduate who is not enrolled at one of the state's medical schools may only be an observer, and an observer must not provide or direct hands-on care, whatever their training. An observer may read the chart and watch interviews, examinations and operations, but may not write in the chart, examine a patient, interview one, order medication or do a procedure. Each of those requires a license.

The visa says the same thing. The State Department's Foreign Affairs Manual allows a visitor to come on a B-1 visa "merely and exclusively to observe" if they pay their own way, and says that practical training needs a different status. The exception for hands-on clerkships covers students of foreign medical schools only and does not apply to graduates. Most observers come on a B-1/B-2 visa or, if their country is in the Visa Waiver Program, with ESTA for up to 90 days. A 2026 paper on short-term clinical training in California concluded that no visa currently exists for short-term, hands-on clinical training for international graduates.

Some states have narrow exceptions, but they are not for Match applicants. Ohio, for example, issues a visiting certificate only to physicians who already hold a full license in another country and have a place in a program run by an Ohio medical school; they may not write orders or prescribe, and the time does not count as residency training. ECFMG Certification does not change any of this: it is what you need to start residency, take Step 3 and later get a license, but it is not itself a license to treat patients.

What observership programs look like

Hospitals and universities run observerships for graduates on their own terms. Four examples from their current pages:

• University of Alabama at Birmingham: graduation within the last five years, Step 1 passed, and English proof (OET Medicine with 350 in listening, reading and speaking and 300 in writing, or TOEFL). Four or eight weeks for a $350 fee. You get an official letter of completion, and there is no direct patient contact or communication.
• UCLA Health: one to three months for a $750 fee, on a B-1 visa or ESTA. Observers take part in no patient care and have no access to the electronic health record.
• Children's Hospital of Philadelphia: two to eight weeks for a $750 fee plus background screening. Its faculty cannot write letters of recommendation for observers, and the hospital says the program must not be used to gain US experience for a residency application.
• St. Mary Medical Center (Pennsylvania): passing USMLE scores, graduation within five years preferred, $1,500 for four weeks plus $250 on acceptance, with weekly feedback.

Read the fine print for two things before you pay: whether a physician will write you a letter, and what the program will call the experience in writing. An observership that ends with only a certificate still shows you know how a US team works, but it will not satisfy a program that asks for hands-on experience or for a letter from a US supervisor.

Research as another way in

A research job in a US department puts you inside a team, and the physicians you work with can write letters. Universities sponsor these positions, often on a J-1 research scholar visa, which lasts up to five years. Two rules to know. After a research scholar program ends, you cannot return in that category for two years. And because you are a medical graduate, the sponsor must certify either that the program involves no patient care, or that any patient contact is incidental and supervised, gives you no responsibility for diagnosis or treatment, and cannot count toward board certification. Research is valued by many academic programs, but it is not clinical experience, and programs that ask for hands-on USCE will not count it as such.

5. Before your first day: vaccines and a TB test

Every host wants health documents before you set foot on a ward, and they take longer to collect than most people expect. Many medical schools use the AAMC's Standardized Immunization Form, which a licensed health professional must sign. The 2026 form asks for:

• Measles, mumps and rubella: two doses of MMR, or blood tests showing immunity.
• Chickenpox (varicella): two doses, or a positive blood test.
• Tdap: one adult dose.
• Hepatitis B: the full vaccine series and a quantitative antibody result (anti-HBs). At least 10 mIU/mL counts as immune; below that you need more doses and a repeat test.
• Influenza: one dose each autumn, for rotations in flu season.
• COVID-19: a current dose for those previously vaccinated. Hospitals differ on whether they require it.
• Tuberculosis: a recent TB test, more on which below.

Hospitals add their own items on top. Among the examples we read: a urine drug screen within four weeks of the start and a criminal background check, in English, from an agency in the country where you study (Cleveland Clinic); an N95 respirator fit test (Washington University in St. Louis); US-valid health insurance; malpractice cover of $1 million per claim and $3 million in total; and online privacy and safety training. Start collecting these two to three months ahead; a missing antibody result can delay you by weeks.

The TB test, if you had BCG

The CDC recommends that every health care worker be screened for tuberculosis when they start: a risk assessment, a symptom check, and a test. There are two kinds of test. The tuberculin skin test injects a protein mixture under the skin and is read 48 to 72 hours later. The interferon-gamma release assay (IGRA) is a blood test; in the US that means QuantiFERON-TB Gold Plus or T-SPOT.TB.

BCG is the reason the choice matters. The US does not generally use the BCG vaccine, but Japan, South Korea, Taiwan, Mexico, Egypt, Jordan, Saudi Arabia, India and many other countries give it in infancy. BCG can make the skin test positive, and there is no reliable way to tell that from a real infection. The blood test is not affected, so the CDC calls it the preferred test for anyone who has had BCG.

There is also a practical reason. The AAMC form accepts either two skin tests or one IGRA, but a skin test used to meet it must have been done in the US. If you are applying from abroad, an IGRA done at home is usually the only TB result you can bring. Check how recent it must be: Mayo Clinic wants it within three months of your start, and Cleveland Clinic and Washington University within twelve. If the result is positive, expect to need a chest X-ray and a record of whether you were treated.

Why a vaccine changes one test and not the other is exactly the kind of thing Step 1 asks. Here is a question from USMLE BANK about it:

6. Letters and the ERAS application

For most programs, the point of US experience is the letter that comes out of it. In ERAS, the AAMC's application service, you can assign up to four letters to each program. The writer uploads the letter, not you; from the 2027 season letters go through the AAMC Letter Writer Portal. You choose whether to waive your right to read it; letters you cannot read are generally taken as more candid. ERAS does not limit who can write a letter: programs do, and many international applicants are asked for letters from US physicians who supervised them clinically. Ask the attending you worked with most, soon after the rotation, while they still remember you.

The experience itself goes in the Experiences section. You can list up to ten experiences, mark three as most meaningful, and describe each one in up to 750 characters. ERAS files clerkships, away rotations, sub-internships and structured observerships under education and training; research and paid work have their own types. Describe what you actually did. Programs that ask for hands-on experience read these entries to tell an elective from an observership, and calling an observership an "externship" does not change what it was.

7. Paying for USCE: what to check

Hospital programs charge fees of a few hundred dollars, and private companies sell "rotations" for far more. In a 2025 survey of 128 international graduates applying in pathology, respondents reported spending an average of $964 (from $50 to $3,000) to secure an observership or externship, and 62% named cost and the small number of places as major obstacles. We found no statement from the AAMC, the ACGME or ECFMG on paying for clinical experience. The clearest guidance comes from the AMA's guidelines for observership programs: preferably run on a not-for-profit basis, with volunteer preceptors, charging the observer only actual costs such as administration and immunizations, and with the observer accepting no pay and doing no examinations or treatment. The AMA also says an observership should not be seen as a mandatory step before residency. In 2025 the AMA still published a list of observership programs, including commercial ones, with a note that listing was not an endorsement; by 2026 that page sent visitors to a page of general questions instead.

Before you pay anyone, ask:

• Where, and who supervises? A named, licensed attending at a hospital you can verify, ideally one with ACGME-accredited residency programs.
• What will I do? If you are a graduate and the program promises hands-on care, ask how that is allowed under the state's law. A clear answer about observing is better than a vague promise.
• Will the supervising physician write a letter? A letter depends on what that physician saw you do. Be wary of anything sold with a "guaranteed" letter.
• What will it be called in writing? The name on the certificate should match what you put in ERAS.
• What does the fee pay for? Compare it with the AMA's standard of actual costs and with the $350 to $1,750 that the hospital observerships above charge.

8. When to do it

Work back from the application. Programs start reading ERAS applications in late September; in the 2027 season that was 23 September 2026. If you are applying in the 2028 season, experience that helps most will end by the summer of 2027, early enough for the letter to be uploaded before programs start reading. Many programs also care about recency, often within one or two years of applying, and about the gap since you last worked clinically.

For most students, that means: Step 1 first, because many hosts require it before an elective; then electives in the final year, applied for through your school four to six months ahead. For graduates: Step 1 and Step 2 CK, then observerships or research while the exams are fresh, with an eye on the program's limit on years since graduation. Whatever you choose, get the vaccines, the antibody results and the IGRA done first; they are the step that most often makes people miss a start date.

Frequently asked questions

Is US clinical experience required for residency?

Not by any national rule. No exam, ECFMG requirement or Match rule requires it. But many programs ask international applicants for it, and each sets its own definition: some require two or three months of hands-on experience and exclude observerships, while others accept observerships or do not require it at all. Check each program's page.

Does an observership count as USCE?

It depends on the program. Some programs say outright that an observership does not count, because the observer does not take part in patient care. Others accept it, or value it without requiring it. An observership still shows you have seen how a US team works, and it counts for more if a physician who knows you will write a letter.

Can a graduate do hands-on clinical work in the US before residency?

Generally not. Practicing medicine requires a state license, and a graduate who is not in a residency has neither a license nor a training permit. State rules such as Iowa's allow international graduates only to observe, and US visa rules allow observation but not hands-on training. The few state exceptions are for physicians already licensed abroad and do not count as residency training.

Which TB test should I get before a US rotation if I had BCG?

An interferon-gamma release assay (IGRA), such as QuantiFERON-TB Gold Plus or T-SPOT.TB. BCG can make the tuberculin skin test positive, but it does not affect the IGRA, and the CDC prefers the IGRA for anyone who has had BCG. The AAMC's standard immunization form also accepts a skin test only if it was done in the US, so an IGRA done at home is usually the practical choice.

How many letters of recommendation can I send to each program?

Up to four per program through ERAS. The writer uploads the letter through the AAMC's Letter Writer Portal, and you choose which letters go to which program. ERAS does not limit who writes them, but many programs ask international applicants for letters from US physicians who supervised them.
