The search for a desirable residency position is an important and stressful process for medical students and medical graduates. After selecting a specialty and identifying preferred programs, the student or graduate must complete application materials, including a transcript, personal statement, and letters of recommendation, and submit those materials to the desired programs. The application process is greatly facilitated by the Electronic Residency Application Service (ERAS) of the Association of American Medical Colleges (AAMC), which allows the candidate to complete the application online and submit documents electronically.1 For those programs that show an interest, the applicant ordinarily must travel to interview at the program sites. Most candidates also participate in the National Resident Matching Program (NRMP). Candidates submit a rank-order list (ROL) of their preferred programs, residency program directors submit a ROL list of preferred candidates, and the matching algorithm produces a best result. Successful candidates are contractually obligated to accept the resulting placement. Candidates who are unsuccessful in being matched must “scramble” in competition with others for the few positions remaining after the Match results are announced.

The process of seeking a residency position is stressful for all candidates, but it is especially so for international medical graduates (IMGs). Before they are eligible to participate in a residency in the United States, IMGs must pass Step 1 (Basic Science) and Step 2 (Clinical Knowledge and Clinical Skills) of the same United States Medical Licensing Examination (USMLE) required of U.S. graduates, and they must have their credentials verified by the Educational Commission for Foreign Medical Graduates (ECFMG). The pass rate in 2008 for first-time IMG takers of Step 1 was only 73%; for Step 2 Clinical Knowledge it was 81%, and for Step 2 Clinical Skills it was 72%. Many who fail on the first try continue taking the examinations, and some eventually pass.2

In the competition for available residency positions, IMGs have a more difficult time because they typically have lower scores on the USMLE, may be graduates of schools unfamiliar to residency program directors, may have problems with visa requirements, and may have to travel much longer distances to interview sites. Even IMGs who are U.S. citizens, many of whom have completed clerkship rotations in the United States, face some of those hurdles. In fact, U.S.-citizen IMGs have lower pass rates on Step 1 and Step 2 Clinical Knowledge than do IMGs who are not U.S. citizens.2,3 Nevertheless, given the array of factors that come into play in the selection process, U.S.-citizen IMGs, as a group, are still more likely to eventually obtain graduate training positions.4

Despite the difficulties they encounter, many IMGs have been capable students, make competent residents,5 perform well as physicians,6,7 and help to diversify the physician workforce.8 They are an important component of the U.S. system of medical care. They make up 23.5% of practicing physicians9 and 27.6% of residents,10 but constitute 47.1% of ERAS applicants11 and 43.8% of NRMP participants.12 The disproportionate numbers of applicants in relation to practicing physicians reflects not only the failure of many IMGs to find a position but also the fact that many IMGs repeat their efforts in one or more additional years.

Although the fact that IMGs apply in more than one year has been known for some time, and although the ECFMG, the NRMP, and the American Medical Association publish data for single years in annual statistical reports,2,12,13 there have been no longitudinal studies demonstrating the ultimate success of IMGs in finding residency positions. That is the subject of the present report.


This work is a joint effort of the AAMC, the NRMP, and the ECFMG. The study was proposed by the ECFMG and endorsed by the NRMP Data Release and Research Committee and the AAMC leadership. In May 2009, a comprehensive reciprocal licensing agreement, signed by all three organizations, provided for the study of a cohort of 10,328 IMGs who were certified by the ECFMG between July 1, 2005 and June 30, 2006.

The ECFMG created a file containing attributes of all IMGs certified in 2005–2006 and shared it with the AAMC and the NRMP. The AAMC and the NRMP matched the file to their records, created extracts describing NRMP and ERAS activity for the same individuals, and then linked the data to those of new residents in GMETrack, a system containing residency records from the National GME Census.10 Several distinct tables were created because of the one-to-many relationships; namely, some individuals applied more than once in ERAS, and some registered more than once with the NRMP. The collection of records applying to an individual can be complex, reflecting repeated unsuccessful and often eventually successful application activity by each person.

To simplify the analysis, each person was followed only until the first entry into a U.S. graduate medical education (GME) program. Subsequent residency positions were ignored for this work.

The data available for this study included those regarding NRMP and ERAS activity through the 2008–2009 application year and residency activity through the first half of 2010. The records from ERAS and the NRMP are complete; AAMC staff estimate that the GMETrack records are at least 95% complete. Because a small percentage of residents are missing from GMETrack, numbers of IMGs in residency positions may be slightly underestimated.

Data have been carefully scrubbed to eliminate any duplicate records. Because we are dealing with population statistics, measures of statistical significance are not appropriate.

In some cases, the records show residency activity prior to ECFMG certification. Although such a path should be impossible, there may be extraordinary circumstances where it may have been permitted, or it may have resulted from erroneous reports. We have included data on the few examples of residencies begun in 2003 and 2004, but it would not be expected that graduates certified in 2005 would be able to find a residency earlier than 2005, and in most cases they would not be able to do so until 2006 or later, because of practical considerations involving the time required for making applications.

The study protocol was approved by the institutional review board of the American Institutes for Research.

Results and Discussion

Characteristics of the IMGs

IMGs come from all over the globe. The cohort included citizens of 143 countries or territories who received medical degrees in 135 different countries or territories. Of the 10,328 IMGs in the cohort, 1,823 were U.S. citizens at the time they began their medical education (US IMGs); they studied in 69 different countries or territories. Table 1 includes the numbers of all IMGs and of US IMGs from the top 20 countries that provided the IMGs' medical education, which account for 69% of the IMGs certified by the ECFMG in 2005–2006. India and Pakistan account for the greatest numbers of IMGs, but US IMGs train predominantly in the Caribbean schools. Schools in Dominica, Grenada, and the Netherlands Antilles account for 55% of US IMGs. In Table 1, the column labeled “Citizens” under the “All IMGs” category reports the numbers of citizens of each country who graduated from any international medical school.

Table 1 also shows the numbers of US IMGs and non-US IMGs who participated in ERAS or the NRMP at any time during the study period and the number who ultimately obtained a residency position. Ninety-one percent of US IMGs were successful, but only 73% of non-US IMGs were.

Seventy-six percent of IMGs indicated a native language other than English, but 75% received at least some of their instruction in English. The cohort was 58% men, and the IMGs were considerably older when they first applied for a residency position than are most U.S. medical graduates. The mean age when the ECFMG certificate was issued was 31.3 years, with a standard deviation of 5.6 years. There often was an interval of one or more years between medical school graduation and certification, and, as we show in the sections that follow, there often was an interval of several years after being certified before an IMG began a U.S. residency. Table 2 reports these statistics separately for US IMGs and non-US IMGs.

Participation in ERAS

Senior medical students in U.S. MD- or DO-granting institutions register with ERAS through the dean's office of their medical school. Ordinarily, registration is permitted only for students who are expected to graduate in the year residency training is to begin. In unusual circumstances, a student might apply to residency programs through ERAS but not graduate on time or perhaps not graduate at all. Students who have graduated in a prior year but who still wish to make a residency application nevertheless must register through the dean's office of the school from which they graduated.

International medical students and graduates register for ERAS through the ECFMG, which first determines whether they are likely to complete the requirements for ECFMG certification in time to begin a residency in the year for which they are applying. It is often the case, however, that an international medical student or graduate will participate in ERAS but fail to complete all of the requirements in time to start a residency.

ERAS transmits a common application, transcripts, deans' letters, letters of recommendation, USMLE scores, and ECFMG certifications to residency programs. It is up to the residency programs to verify the completeness of those credentials before offering a residency position.

Table 3 displays ERAS activity for the cohort of international medical students and graduates who were certified in academic year 2005–2006. Note that in a number of cases, students participated in ERAS before being certified by ECFMG. In 31 cases, applicants seemed to have started a residency program more than a year before ECFMG certification. Those may be exceptional situations or represent reporting errors.

In an additional 150 cases, applicants started a residency in the same year in which they were certified by the ECFMG. All members of our study cohort were certified on or after July 1, 2005, the same date on which new residents normally begin their appointments, which indicates that they may have started a residency before being certified. In many of those cases, however, the reported starting date for the residency was a few days after an early July certification date. In other cases, it is possible that residency programs reported a nominal starting date of July 1, 2005, when the actual starting date was a few days later. There are nevertheless some additional cases where graduates were reported to have started a residency more than a few days before being certified.

In ERAS 2005, there were 1,006 IMG applicants from the study cohort, but only 99 were successful, because most of them were not certified in time to begin a residency program at the normal start date. An additional 51 managed to start a residency without applying through ERAS.

ERAS 2006 was the first year in which most of the newly certified IMGs could have applied for residency. The majority did apply through ERAS in that year, and 4,601 were successful. Of the 2,283 who did not apply through ERAS, 139 nevertheless gained entry to a residency program.

Some members of the cohort may have delayed their applications because of practical considerations, such as the need to obtain a visa or make travel arrangements. Many of those individuals, as well as others who were unsuccessful in 2006, applied again in ERAS 2007. In that year there were 3,967 IMG participants, more than half of whom were successful. As in previous years, a substantial number found positions without using ERAS.

IMGs who were certified in 2005–2006 continued to apply through ERAS in 2008 and 2009, though in diminishing numbers. Applications from this cohort will surely be seen in the data for ERAS 2010 and ERAS 2011 as well. In all, 76% of IMGs in the study cohort had obtained a residency position before July 1, 2009, and it is likely that a few more will be successful in the years to come.

Participation in the NRMP

IMGs may register with the NRMP without being certified by the ECFMG, but they are withdrawn from the Match by the NRMP if they have not passed the ECFMG examination requirements by the deadline for submitting an ROL. IMGs may withdraw themselves from the Match if they find a position outside the Match or for any other reason. If they wish to continue, they must certify an ROL of preferred programs before the Match deadline.

Some residency programs do not participate in the NRMP, and even those that do participate are permitted by their agreement with the NRMP to accept IMGs before the Match. An applicant obtaining such a position ordinarily would withdraw from the Match. Details in the NRMP Match Participation Agreement are available on the NRMP Web site.

Even if they do not withdraw, many IMGs do not certify an ROL. If they have been unsuccessful in obtaining any interviews, there is little point in participating in the Match because no program would be expected to rank such candidates.

A total of 9,115 members of the cohort had registered with the NRMP through the 2009 Match year. The 1,213 who did not register either sought a position outside the Match or did not seek a GME position in the United States.

Participation by the cohort in the NRMP by Match year is shown in Table 4. New applicants are those who had never before registered with the NRMP; repeat applicants had registered in at least one prior year. The number who successfully matched in each group is also shown. In recent years, less than half of IMG candidates who certified an ROL successfully matched.12

Table 4:
Participation of International Medical Graduates (IMGs) in the National Resident Matching Program (NRMP), 2003–2009

A small number of candidates registered with the NRMP for the 2003 and 2004 Main Residency Matches even before they were certified. As required by the rules, NRMP records show that all but four of those applicants were withdrawn. The single case of an applicant who matched in 2004 before being certified should not have been possible and may be an error. Most applicants certified in 2005 would have been unable to register for the 2005 Match, but 902 managed to do so, including 85 who had registered in an earlier year. Most of the 904 did not certify an ROL, but 114 did, and 38 actually matched to a residency program open to applicants without prior GME (a first-year residency program).

Almost three-fourths (73%) of those who registered with the NRMP did so for the first time in 2006, the first year when all would have been eligible to participate. It is noteworthy, however, that a substantial percentage (13%) did not register until 2007, and some continued to add their registrations to the system in 2008 and 2009.

In 2007, the second Match year available to all members of the cohort, there were almost twice as many repeat applicants as first-time applicants. Repeat applicants continued to register in 2008 and 2009, and it is likely that even more will be found in the next year's pool of applicants. As a group, IMGs are very persistent in seeking a U.S. GME position.

Pathways into GME for IMGs

Table 5 displays the participation in ERAS, the NRMP, and GME by the study cohort's IMGs, who were certified in 2005–2006. The data for each year include only candidates who had not yet entered GME at the beginning of that year. The numbers in parentheses are the new residents each year from each group of candidates.

Table 5:
Participation in ERAS, the NRMP, and GME by International Medical Graduates (IMGs) Certified by the ECFMG in 2005–2006

If an applicant has not met the ECFMG examination requirements by the NRMP deadline for certifying an ROL, the applicant is withdrawn from the Match by the NRMP. There is nothing to prevent such a person from registering with ERAS and the NRMP, however, and it might make sense for a person who expected to be certified in time to start a residency to do so in anticipation of that eligibility. Although it is possible for a person certified in 2005 to participate in ERAS and even to register for the NRMP in 2005, most of those candidates first registered with ERAS and the NRMP in 2006. Table 5 shows a few anomalous cases where applicants who may have been ineligible to begin a residency nevertheless participated in ERAS and NRMP. Most of those anomalous applicants did not find a residency; those who did likely found a position outside of the NRMP.

For 2006, the first year in which most candidates were eligible to participate in ERAS and the NRMP, there were 10,147 candidates without a residency position at the beginning of the academic year. The majority (73%) participated in both ERAS and the NRMP. Of the 10,147 candidates, 2,191 participated in neither ERAS nor the NRMP, but 128 of those applicants nevertheless started a residency. Those few may have taken advantage of a personal relationship, perhaps at the hospitals where they participated in clerkships.

A total of 500 candidates participated in ERAS but not in the NRMP, and 205 were successful in starting a residency. An even smaller number participated only in the NRMP, and 11 were successful in finding a residency.

Most of the graduates still without a residency in 2006, a total of 7,364, participated in both ERAS and the NRMP. Although only 2,729 of these dual participants actually matched, an additional 1,667 found a position outside of the Match, with the result that a total of 4,396 were successful.

Of the entire 10,147 graduates without a residency in 2006, 5,407 (53%) failed to find a residency position in that year. Many applied again in 2007 and subsequent years, but with each passing year the success rate of the remaining graduates declined. Of those who remained in 2007, 41% were successful; in 2008 only 17% of those remaining were successful. After the close of the 2009 cycle, 76% of the original cohort had obtained residency positions, and it is likely that a few more will be successful in years to come.


IMGs are persistent in their pursuit of GME positions. They usually take advantage of ERAS and participate in the NRMP. If unsuccessful, they try again, often multiple times. Eventually, more than three-fourths of this study cohort successfully entered U.S. GME. Nonetheless, NRMP data demonstrate the declining success rate of IMGs in the Match. Between the 2005 and 2009 Matches, the percentage of IMGs who certified ROLs and matched to first-year residency positions fell from 54.7% to 47.8% for U.S. citizens and from 55.6% to 41.6% for non-U.S. citizens.12 Because enrollment in U.S. MD-granting and DO-granting medical schools is increasing much more rapidly than the number of entry-level residency positions,10,14 competition for residency positions will intensify, especially for IMGs.

In a subsequent work, we will compare the characteristics of successful and unsuccessful IMG candidates, including examination performance, and further elucidate the differences between US IMGs and non-US IMGs. Given the contribution of IMGs to the U.S. physician patient care workforce, the data provided in the current report, combined with the results from additional past and future longitudinal investigations, can inform relevant physician workforce policies and help organizations involved with the certification, selection, and education of IMGs to better plan for future activities.
