The Interstate Medical Licensure Compact (IMLC) gives eligible physicians a streamlined path to obtain medical licenses in multiple member states — a significant advantage for Locum providers who want geographic flexibility without submitting full duplicate applications to every state board. As of 2026, more than three dozen states participate in the compact, though eligibility rules and processing times still require careful planning.
What Is the Interstate Medical Licensure Compact?
The IMLC is an agreement among participating U.S. states that allows qualified physicians to obtain additional licenses through a centralized application process administered by the Interstate Medical Licensure Compact Commission. Instead of submitting separate full applications to each state medical board, physicians apply through their declared state of principal license (SPL) — typically where they live, work, or hold their primary medical license — and request compact privileges in other member states.
Who Administers the Compact?
The Interstate Medical Licensure Compact Commission processes applications and coordinates with member state boards. Individual states still issue the licenses and retain authority to deny or restrict privileges based on disciplinary history or eligibility failures.
IMLC Eligibility Requirements
Not every physician qualifies for the compact pathway. Core requirements include:
- State of principal license: You must hold a full, unrestricted medical license in a compact member state that serves as your SPL.
- Board certification or eligibility: ABMS or AOABOS certification — or eligibility within a defined window for recent graduates.
- No disciplinary history: Active investigations, restrictions, or significant disciplinary actions on any state license typically disqualify compact eligibility.
- Graduate of accredited medical school: MD or DO from an LCME- or COCA-accredited institution.
- Completed ACGME- or AOA-accredited graduate medical education: Residency training verification is required.
Physicians who do not meet compact criteria must use traditional full applications for each non-compact or non-eligible state — a longer process AZ Locums licensing specialists manage alongside compact applications.
How IMLC Licensing Works Step by Step
Understanding the sequence helps locums physicians plan multi-state assignment strategies.
Step 1: Confirm SPL and Compact Status
Verify your home or primary practice state participates in the IMLC and can serve as your SPL. If your SPL state is not a compact member, you cannot use the IMLC pathway regardless of where you want to practice.
Step 2: Submit the Compact Application
Apply through the SPL state’s compact process with required fees, background check, and fingerprinting. The SPL verifies your eligibility and forwards requests for additional state licenses to the commission.
Step 3: Receive Additional State Licenses
Member state boards issue licenses after commission coordination. Compact licenses are full, unrestricted medical licenses — not temporary or limited permits. Processing times vary; many physicians receive additional state licenses in one to three weeks after SPL approval, though some states take longer.
Step 4: Maintain Compliance in All Licensed States
Compact licenses require ongoing compliance with continuing medical education, renewal fees, and disciplinary reporting in every state where you hold a license. A disciplinary action in one state can affect all compact licenses.
IMLC Member States and Locum Strategy
For locums physicians, the practical value of the IMLC is assignment access. High-volume locums markets — Texas, Colorado, Arizona, Wisconsin, and many Southeastern states — participate in the compact. Holding licenses in three to five strategic member states lets you respond quickly when recruiters present urgent coverage needs.
Compare assignment availability on our job board and state pages such as Texas Locum jobs. Physicians licensed in Texas plus two neighboring compact states can often accept cross-border assignments without waiting for new board processing.
IMLC vs. Traditional Full-State Applications
| Factor | IMLC Pathway | Traditional Full Application |
|---|---|---|
| Eligible states | Compact member states only | All states including non-compact (CA, NY, FL*, etc.) |
| Typical processing time | 1–3 weeks per additional state (after SPL approval) | 4–12+ weeks per state |
| Application duplication | Centralized through SPL | Separate full application to each board |
| Fingerprinting | Often once through SPL process | May repeat per state |
| Cost | Compact fees plus per-state license fees | Full application fees per state |
*Florida participates in the IMLC; California and New York do not — physicians targeting those markets need traditional applications regardless of compact status.
Multi-State Licensing for Advanced-Practice Providers
The IMLC applies to physicians (MD/DO) only. Nurse practitioners and physician assistants follow separate multi-state frameworks.
Nurse Practitioners and the NLC
The Nurse Licensure Compact (NLC) allows eligible RNs and APRNs to practice in member states with a multistate license. Not all states participate — California, Oregon, and several others require individual APRN licenses. NP locums providers should maintain licenses in high-demand non-compact states separately if those markets are career targets.
Physician Assistants
PA multi-state licensing follows individual state medical or PA board applications. Some states have pursued PA compact legislation, but PA locums licensing remains primarily a state-by-state process in 2026. AZ Locums coordinates PA applications and DEA registrations alongside physician licensing.
Common IMLC Mistakes Locums Physicians Should Avoid
- Assuming compact covers all 50 states: Non-member states still require full applications — plan ahead for California, New York, and other major markets outside the compact.
- Letting SPL license lapse: Your compact eligibility depends on a valid SPL; renewal lapses suspend compact privileges.
- Ignoring state-specific DEA requirements: A medical license alone does not authorize prescribing — DEA registrations must match practice locations.
- Applying for locums assignments before licenses issue: Hospital privileging requires an active license number; compact processing must complete before credentialing begins.
- Underestimating renewal costs: Multi-state licenses carry cumulative renewal fees — budget annually across all licensed states.

How AZ Locums Helps with IMLC and Multi-State Licensing
Locums placement speed depends on licensure readiness. AZ Locums licensing specialists:
- Identify whether IMLC or traditional applications fit your target markets
- Pre-fund application and compact fees for qualifying assignments
- Track board status and follow up on pending verifications
- Coordinate DEA registrations tied to new practice locations
- Align licensing strategy with your assignment preferences and recruiter pipeline
Physicians who invest in multi-state licensure upfront — especially through the IMLC — consistently access more assignments, capture urgent coverage premiums, and start work sooner than providers limited to a single-state license.
Frequently Asked Questions
Does the IMLC give me one license for all member states?
No. You receive separate full medical licenses issued by each member state you request — the compact streamlines the application process but does not create a single multi-state license document.
Can I use the IMLC if I have a history of malpractice claims?
Claims alone do not automatically disqualify you, but boards review malpractice history during SPL verification. Undisclosed claims discovered during background review can delay or deny compact eligibility. Full transparency during application is essential.
How long does initial IMLC setup take for a new locums physician?
First-time compact setup through your SPL typically takes two to four weeks for SPL verification, then one to three weeks per additional state requested. Physicians should initiate the process before accepting assignments in new compact states — not after signing a contract.
Do locums agencies pay for IMLC and state license fees?
AZ Locums deposits licensing fees for qualifying assignments as part of placement support. Fee handling terms are confirmed with your recruiter before applications are submitted. Renewal fees for maintaining licenses long-term are generally the provider’s responsibility.
