If you are planning to take the USMLE Step 1, the first thing to confirm is whether you meet the eligibility requirements. The rules are set by the Educational Commission for Foreign Medical Graduates (ECFMG) for international medical graduates (IMGs) and by the NBME for US/Canadian students. This page breaks down every criterion — education, age, nationality, and special cases — so you can move forward with confidence.
Education Prerequisites
To be eligible for USMLE Step 1, you must be enrolled in or a graduate of a medical school that meets specific standards.
For US and Canadian Medical Students
- You must be officially enrolled in a medical school program leading to an MD or DO degree that is accredited by the LCME or the COCA.
- You can take Step 1 after completing at least two years of medical school (typically the pre-clinical years).
- Most students take Step 1 at the end of their second year.
For International Medical Graduates (IMGs)
- You must be enrolled in or a graduate of a medical school listed in the World Directory of Medical Schools (WDOMS) that meets ECFMG requirements.
- The school must have a valid ECFMG sponsorship note.
- You must submit your medical diploma and transcripts for verification through ECFMG's EPIC or directly via your school.
- You need a final medical diploma (or proof of imminent graduation) before you can apply for Step 1.

Age Limits
There is no official age limit for USMLE Step 1. Candidates of any age can apply, provided they meet education and other eligibility criteria. However, some residency programs may have their own age-related preferences, but this is not a USMLE rule.
Nationality and Citizenship
No nationality restrictions. USMLE Step 1 is open to all nationalities. There is no requirement to be a US citizen or permanent resident. However, your eligibility pathway depends on your medical school location:
- US/Canadian students apply via the NBME.
- All other candidates (IMGs) apply through ECFMG.
If you are an Indian medical graduate (MBBS), you are considered an IMG and must go through ECFMG. You do not need a US visa to take Step 1 — many candidates take the exam in India at Prometric centres.
Special Category Rules
Graduates from Non-WDOMS Schools
If your medical school is not listed in the World Directory, you are not eligible for USMLE Step 1. There is no exception. Check your school's status on the WDOMS website before applying.
Fifth Pathway Candidates
This pathway is largely obsolete. If you are a US citizen who completed medical education abroad and then completed a one-year clinical clerkship in the US, you may be eligible. Verify with ECFMG directly.
Re-applicants and Previous Attempts
- There is no limit on the number of times you can take Step 1, but you must wait at least 60 days between attempts.
- You cannot take Step 1 more than four times in a 12-month period.
- If you have passed Step 1 previously, you cannot retake it to improve your score — only failing candidates may retake.
Graduates from Indian Medical Colleges
- Your MBBS degree from an MCI/NMC-recognized college is accepted if the college is in WDOMS.
- You must have completed your internship (or be in the final year) to get your final diploma.
- ECFMG requires that your medical school verifies your credentials online via the EMSWP system.

Common Misconceptions
- “I need a US visa to take Step 1.” No. You can take it in your home country or any Prometric centre globally.
- “I can only take Step 1 in the US.” No. Step 1 is offered at Prometric centres worldwide.
- “My MBBS from India is not accepted.” It is, as long as your college is in WDOMS.
- “I must be a US citizen.” No. Nationality is not a factor.
