Physician Licensing Requirements by State (2026 Guide)

Obtaining a physician license in the United States is a state-regulated process. There is no single national medical license. Each state and certain U.S. jurisdictions establish their own requirements for medical education, postgraduate training, licensing examinations, credential verification, and other eligibility criteria.

For physicians planning to practice in the U.S., understanding physician licensing requirements by state before applying can help avoid application delays, incomplete applications, and eligibility problems.

This 2026 guide explains the major requirements physicians should consider when applying for and maintaining a medical license, including medical education, postgraduate training, USMLE and COMLEX-USA examinations, international medical graduate (IMG) requirements, credential verification, examination attempts and time limits, CME, and multi-state licensing.

Important: Medical licensing requirements can change. FSMB reviews and updates its state-specific information annually and/or at the request of a medical board. Physicians should use FSMB information as a starting point and confirm the latest requirements directly with the applicable state medical board before applying.

What Are the Core Requirements for a Physician License?

Although requirements vary by jurisdiction, state medical boards generally evaluate several areas:

• Medical education
• Postgraduate medical training
• Licensing examination results
• Professional and employment history
• Credential verification
• Criminal and disciplinary history
• Malpractice history, where applicable
• Fitness to practice
• Other state-specific documentation

The exact requirements can depend on the physician's medical degree, medical school, postgraduate training, examination history, license history, and whether the physician is an international medical graduate.

The key point is that meeting the requirements in one state does not automatically qualify a physician for licensure in another state.

Physicians should therefore review the requirements of the specific state where they intend to practice rather than relying on a general national rule.

Medical Education and Postgraduate Training Requirements

A physician generally must graduate from a qualifying medical school and complete the postgraduate training required by the state where they are seeking licensure.

Postgraduate medical training is a particularly important area of state variation. Many states require at least one year of qualifying postgraduate training, while others require two or three years or impose additional training conditions. Requirements can also differ for U.S. and Canadian graduates and international medical graduates.

For example, current FSMB information shows different requirements in states including:

• Florida: 1 year generally and 2 years for IMGs
• Iowa: 1 year generally and 2 years for IMGs
• Maryland: 1 year generally and 2 years for IMGs
• Massachusetts: 2 years for domestic graduates and 3 years for certain IMGs
• New York: 1 year generally and 3 years for IMGs

These examples demonstrate why physicians should not rely on a universal "one year" or "three years" residency rule.

Some states also have alternative licensing pathways for internationally trained physicians. These pathways may have specific requirements involving postgraduate training, recent clinical experience, supervised practice, employment, examinations, ECFMG certification, or other eligibility criteria.

Physicians considering an alternative IMG pathway should confirm the current requirements directly with the relevant state medical board.

USMLE and COMLEX-USA Requirements

Licensing examinations are another major component of physician licensure.

USMLE

The United States Medical Licensing Examination (USMLE) consists of:

• Step 1
• Step 2 Clinical Knowledge (CK)
• Step 3

Step 3 has additional eligibility requirements, including successful completion of Step 1 and Step 2 CK. For applicable international medical graduates, ECFMG Certification eligibility is also required for USMLE Step 3 eligibility.

Passing the USMLE does not by itself grant a medical license. State medical boards establish their own licensing requirements and may impose additional examination, training, documentation, or professional-history requirements.

USMLE Attempt Limits

The USMLE program permits four attempts per Step. An examinee who has attempted a Step four or more times without passing is ineligible to apply for further USMLE Steps under the program's applicable rules.

State medical boards may impose additional examination attempt limits, time limits, waivers, or other requirements.

For example, current FSMB information shows that:

• Georgia limits USMLE attempts to three per Step.
• Iowa allows six attempts for Steps 1 and 2 and three attempts for Step 3.
• Kansas requires completion of the USMLE or COMLEX sequence within seven total attempts.
• Maryland permits unlimited attempts but has additional requirements after multiple failures.
• Massachusetts limits Step 3 attempts and has a seven-year examination completion requirement.

The USMLE's four-attempt rule therefore should not be treated as a universal state licensing rule.

Physicians should check both the current USMLE requirements and the licensing rules of the state where they intend to practice.

COMLEX-USA and Osteopathic Physician Licensing

Osteopathic physicians commonly use the COMLEX-USA examination pathway for licensure.

State requirements can differ for MD and DO applicants, including examination requirements, examination attempts, postgraduate training, and continuing education.

Depending on the jurisdiction, physicians may need to confirm:

• Which examinations are accepted
• Required COMLEX-USA levels
• Whether USMLE results are required or accepted
• Examination attempt limits
• Examination completion deadlines
• Postgraduate training requirements

Physicians should not assume that USMLE and COMLEX-USA requirements are identical in every state.

2026 USMLE Registration Changes

USMLE services changed in January 2026 as part of a broader service transition.

Students and graduates of U.S. medical schools now register for USMLE examinations through NBME, while students and graduates of eligible medical schools outside the United States register through FSMB.

The transition changed how USMLE services and registration are administered. It did not eliminate ECFMG Certification requirements for international medical graduates.

ECFMG continues to determine whether eligible international medical graduates meet ECFMG Certification requirements, and ECFMG Certification remains an important part of the IMG pathway for U.S. medical practice.

Physicians should therefore distinguish between USMLE registration and ECFMG Certification. The organizations involved in USMLE registration changed in 2026, but ECFMG's role in determining certification eligibility continues.

Physician Licensing Requirements for International Medical Graduates

International medical graduates generally have additional requirements when seeking U.S. medical licensure.

Depending on the state and applicant pathway, these may include:

• ECFMG Certification
• USMLE Step 1 and Step 2 CK
• Applicable ECFMG Pathway requirements
• OET Medicine requirements for applicable Pathways
• Medical school credential verification
• Additional postgraduate training
• Background checks
• Professional license or registration verification
• State-specific IMG requirements

For current ECFMG Certification requirements, IMGs must satisfy the medical science examination requirement by passing USMLE Step 1 and Step 2 CK.

The clinical and communication skills requirements can generally be satisfied through an applicable ECFMG Pathway, which includes a satisfactory Occupational English Test (OET) Medicine score. A valid passing performance on the former USMLE Step 2 Clinical Skills examination can also satisfy these requirements when it remains valid for ECFMG Certification.

There is no universal requirement that every IMG complete three years of U.S. residency. Qualifying postgraduate-training requirements vary by state and by licensing pathway.

Some states have also created or considered alternative pathways for internationally trained physicians. These pathways may have additional requirements involving recent clinical experience, supervised practice, employment, examinations, or other conditions.

Because IMG requirements can be particularly complex, applicants should verify both ECFMG requirements and the requirements of the state medical board where they plan to practice.

Credential Verification and Application Requirements

Passing the required licensing examinations is only one part of a medical license application.

Depending on the state and applicant, physicians may need to provide or authorize verification of:

• Medical school diploma and transcripts
• Residency and postgraduate training
• Examination history
• ECFMG documentation for applicable IMGs
• Professional licenses
• Employment history
• Malpractice history
• Disciplinary history
• Criminal background information
• Fingerprints
• Professional references
• Identity and eligibility documentation

Some state medical boards require or accept the Federation Credentials Verification Service (FCVS). The role of FCVS varies by jurisdiction: some boards require it, while others accept or recommend it.

Physicians should begin gathering documents early. Medical schools, residency programs, licensing authorities, and other organizations may take time to respond to verification requests.

Applicants should also check whether their target state uses the Uniform Application for Physician State Licensure, which can help streamline the submission of core application information to participating boards.

Physician License Renewal and CME

Continuing medical education (CME) requirements are primarily associated with maintaining and renewing a physician license, although individual jurisdictions may impose education requirements in other circumstances.

CME requirements vary considerably by state and may differ between MD and DO licensees. Some states also require specific education in areas such as:

• Controlled-substance prescribing
• Opioid prescribing
• Medical ethics
• Risk management
• Professional boundaries
• Other state-mandated topics

Physicians practicing in multiple states should maintain separate renewal calendars because each license may have different renewal dates, CME requirements, and mandatory subject areas.

A CME course that satisfies one state's requirements does not necessarily satisfy every requirement in another state.

Multi-State Physician Licensing and the IMLC

Physicians who practice across multiple states may need multiple state licenses.

The Interstate Medical Licensure Compact (IMLC) provides an expedited pathway for eligible physicians seeking licenses in multiple participating jurisdictions.

The Compact does not create a national physician license. Physicians still receive individual licenses from participating states and territories.

According to the IMLCC's July 2026 snapshot, reporting information as of June 30, 2026, the Compact included 44 member states, two U.S. territories, and 59 participating licensing boards. Alaska became the 44th member state in June 2026.

Eligibility depends on meeting the Compact's requirements, including criteria related to the physician's State of Principal License, medical education, postgraduate training, examination history, board certification or another qualifying pathway, and professional history.

The IMLC can be particularly useful for physicians practicing across multiple states, including physicians working in locum tenens and certain telemedicine settings.

Because Compact membership and requirements can change, physicians should check the IMLC's current participating-jurisdiction list and eligibility criteria before relying on the expedited pathway.

Physician Licensing for Locum Tenens and Multi-State Practice

Physicians accepting assignments in multiple states should determine licensing requirements before starting clinical work.

Before accepting an assignment, verify:

1. Whether a state medical license is required
2. Whether the license must be active and unrestricted
3. Whether the physician qualifies for the IMLC
4. Whether state controlled-substance registration and/or DEA registration requirements apply
5. Whether facility credentialing or privileging is required
6. Whether additional state-specific documentation is needed

A medical license in one state generally does not authorize a physician to independently practice medicine in another state.

Licensure vs. Credentialing

Medical licensure, facility credentialing, hospital privileging, payer enrollment, and controlled-substance registration are separate processes.

A physician may need to complete several of these processes before beginning a particular clinical assignment.

For locum tenens physicians, starting licensing and credentialing work early can help reduce administrative delays between accepting an assignment and beginning clinical practice.

Common Physician Licensing Mistakes

Assuming Every State Has the Same Requirements

Residency, examination, credential verification, and renewal requirements vary by jurisdiction.

Looking Only at USMLE Attempts

The USMLE program has its own attempt limits, but state medical boards may impose stricter limits or additional requirements after repeated examination failures.

Some states also impose time limits for completing the examination sequence.

Assuming All IMGs Need Three Years of Residency

IMG requirements vary considerably by state and by licensing pathway. Some jurisdictions also offer alternative pathways for internationally trained physicians.

Confusing Licensure With Credentialing

A medical license authorizes practice under the laws of the relevant jurisdiction. Facility credentialing, hospital privileging, payer enrollment, and controlled-substance registration are separate requirements that may apply to a particular job or assignment.

Applying Before Documents Are Ready

Missing transcripts, training verification, examination records, references, or other documentation can delay an application.

Assuming the IMLC Is a National License

The Compact streamlines the process for eligible physicians seeking licenses in participating jurisdictions. It does not replace state-issued licenses.

Frequently Asked Questions About Physician Licensing

How do I get a physician license in the U.S.?

You generally need qualifying medical education, postgraduate training, licensing examinations, credential verification, and state-specific documentation. The exact requirements depend on the state and your individual qualifications.

Can I use one physician license in multiple states?

Generally, no. Physicians typically need authorization in every state where they practice. Eligible physicians may use the IMLC to streamline applications to participating jurisdictions.

Do all states require the same residency training?

No. Postgraduate training requirements vary by state and can differ for U.S.-trained physicians, Canadian graduates, and IMGs.

How many times can I take the USMLE?

The USMLE program permits four attempts per Step, but individual state medical boards can impose additional examination attempt limits or other licensing requirements.

Do IMGs need ECFMG Certification?

ECFMG Certification is an important part of the U.S. pathway for international medical graduates. Current ECFMG requirements include passing USMLE Step 1 and Step 2 CK and satisfying the applicable clinical and communication skills requirements.

For applicants using an ECFMG Pathway, this includes a satisfactory OET Medicine score.

Does the IMLC give a physician one national license?

No. The IMLC does not create a national medical license. Eligible physicians use the Compact's expedited process to obtain separate licenses from participating jurisdictions.

How long does physician licensing take?

There is no universal processing time. The timeline can depend on application completeness, credential verification, examination history, background checks, board workload, and the physician's individual circumstances.

How DirectShifts Can Help

DirectShifts can help physicians navigate the administrative licensing process, organize documentation, manage applications, track outstanding requirements, and support multi-state licensing needs.

For physicians working in locum tenens or considering assignments across multiple states, understanding licensing and credentialing requirements early can help reduce avoidable administrative delays.

Whether you are a U.S.-trained physician, osteopathic physician, resident, or IMG, understanding the requirements before applying can help you prepare more efficiently.

Final Takeaway

Physician licensing in the United States is state-specific. The key areas physicians should review are:

• Medical education
• Postgraduate training
• USMLE or COMLEX-USA requirements
• Examination attempts and time limits
• Credential verification
• IMG and ECFMG requirements
• State-specific application requirements
• License renewal and CME
• Multi-state licensing and IMLC eligibility
• Facility credentialing and other practice-specific requirements

Because regulations can change, physicians should verify current requirements directly with the relevant state medical board before applying.

FSMB's state-specific licensing information is a useful starting point. FSMB reviews and updates its information annually and/or at the request of a medical board, but physicians should contact the relevant board for the most current requirements.
