Introduction
The Interstate Medical Licensure Compact (IMLC) has transformed how physicians obtain licenses to practice in multiple states. Since its creation, the compact has processed over 25,000 license applications and now includes 42 states plus Washington D.C. and Guam—covering approximately 80% of the U.S. physician population.
For physicians who practice telemedicine across state lines, work locum tenens assignments, or maintain practices in multiple states, the IMLC offers an expedited pathway to multi-state licensure. However, it's crucial to understand what the IMLC is and isn't: it provides expedited licensure, not a single multi-state license.
This comprehensive guide covers everything you need to know about the Interstate Medical Licensure Compact in 2026, including participating states, eligibility requirements, the application process, and the significant upcoming change: Michigan's withdrawal effective March 28, 2026.
What Is the Interstate Medical Licensure Compact?
Key Concept: Expedited Licensure, Not a Multi-State License
The IMLC is not a single license that allows you to practice in multiple states. Instead, it provides:
| What IMLC Is | What IMLC Is Not |
|---|---|
| An expedited application process | A single multi-state license |
| A pathway to multiple separate state licenses | A replacement for state licensing |
| A voluntary program | Mandatory for any physician |
| A streamlined credentialing verification | An exemption from state requirements |
Each state still issues its own individual license. The IMLC simply makes it faster and easier to obtain those licenses through a single application.
How the IMLC Works
- Single Application: Apply through the IMLC portal
- Eligibility Verification: IMLC confirms you meet compact requirements
- State Selection: Choose which participating states you want licenses in
- Separate Licenses Issued: Each state issues its own license
- Individual Renewal: Renew each state license according to that state's rules

Critical Update: Michigan Withdrawal
Michigan is withdrawing from the IMLC effective March 28, 2026.
| Date | Impact |
|---|---|
| Through March 27, 2026 | Michigan continues issuing IMLC licenses |
| March 28, 2026 | Withdrawal effective |
| After March 28, 2026 | Direct application to Michigan required |
Legislation: MCL 333.16189 (2023 Public Act 124)
If you need a Michigan license, apply through IMLC before March 28, 2026, or plan to apply directly to Michigan after that date.
IMLC Eligibility Requirements
Approximately 80% of U.S. physicians meet IMLC eligibility criteria. Requirements include:
Basic Eligibility Criteria
| Requirement | Details |
|---|---|
| Medical Degree | MD or DO from accredited U.S./Canadian school, or ECFMG certification |
| Residency | Completed ACGME or AOA accredited residency |
| Board Certification | Specialty certification (or actively practicing 5+ years without certification) |
| License in Good Standing | Active, unrestricted license in State of Principal Licensure |
| No Disciplinary Actions | No history of disciplinary actions |
| No Criminal History | No convictions that would disqualify under state laws |
| No Controlled Substance Actions | No DEA restrictions |
| No Medicare/Medicaid Sanctions | Not excluded from federal programs |
State of Principal Licensure (SPL)
Your SPL is the state where you can demonstrate the strongest connection. This is typically the state where you:
- Have your primary residence, OR
- Practice medicine the majority of the time, OR
- Completed most recent medical training
Important: Connecticut and Vermont are not currently eligible as States of Principal Licensure. You can obtain IMLC licenses for these states only if you qualify through another SPL state.
IMLC Application Process
Step 1: Verify Eligibility
Before applying, confirm you meet all eligibility criteria:
- Valid medical degree (MD/DO or ECFMG certified)
- Completed accredited residency
- Board certified (or 5+ years active practice)
- Clean disciplinary history
- No criminal convictions
- No DEA restrictions
- Not excluded from Medicare/Medicaid
- Active unrestricted license in SPL state
Step 2: Create IMLC Account
- Visit imlcc.org
- Create an account
- Complete the pre-application questionnaire
- Receive eligibility determination
Step 3: Complete Application
- Submit application through IMLC portal
- Provide required documentation:
- Identification
- Medical school transcripts
- Residency verification
- Board certification documentation
- SPL license information
- Pay IMLC application fee (~$700)
Step 4: Select States
- Choose which participating states you want licenses in
- Pay each state's individual licensing fee
- Meet any state-specific requirements
Step 5: License Issuance
- IMLC verifies credentials with state medical boards
- Each selected state reviews and issues license
- Typical processing time: 2-4 weeks
IMLC Fees
Application Fees
| Fee Type | Amount | Notes |
|---|---|---|
| IMLC Application | ~$700 | One-time application processing |
| State Fees | Varies | Each state charges its own fee |
| Total | $700 + state fees |
Sample Total Cost (3 States)
| Component | Amount |
|---|---|
| IMLC Application | $700 |
| Texas License | ~$491 |
| Florida License | $360 |
| Georgia License | $350 |
| Total | ~$1,901 |
Renewal Fees
IMLC licenses renew according to each state's normal schedule and fees. There is no separate IMLC renewal fee—you renew directly with each state.
Benefits of IMLC
Speed
| Traditional Licensure | IMLC Licensure |
|---|---|
| 3-6 months per state | 2-4 weeks for multiple states |
| Separate applications for each state | Single application |
| Multiple credential verifications | One verification process |
Convenience
- Single application for multiple states
- Centralized credential verification
- Streamlined documentation process
- Online application portal
Cost Efficiency
- Reduced administrative burden
- Fewer duplicate credentialing fees
- Time savings translate to earlier practice start
Limitations of IMLC
What IMLC Doesn't Do
- Not a multi-state license: Each state issues separate licenses
- Doesn't waive state requirements: CME, renewals follow state rules
- Doesn't cover non-participating states: California, New York, Oregon not included
- Doesn't eliminate state fees: You still pay each state's licensing fee
- Doesn't guarantee approval: States can still deny licenses
Disciplinary Reciprocity
If a participating state takes disciplinary action against your license:
- All IMLC states are notified
- Other states may initiate their own investigations
- Disciplinary actions may affect all your IMLC-issued licenses
This interconnection is both a benefit (consistent standards) and a risk (widespread impact of any disciplinary issue).
IMLC and Telemedicine
The IMLC has become increasingly important for telemedicine practice:
Why IMLC Matters for Telemedicine
- Telemedicine appointments occur in the patient's state
- You must be licensed in the state where the patient is located
- IMLC makes obtaining multiple licenses practical
- Post-COVID telemedicine expansion has increased multi-state practice
Telemedicine Considerations
| Scenario | Requirement |
|---|---|
| Patient in Texas, you in California | You need Texas license |
| Patient in New York, you in Texas | You need New York license (not in IMLC) |
| Patients in 10 IMLC states | IMLC can get all 10 licenses efficiently |
Who Should Use IMLC?
Ideal Candidates
- Telemedicine physicians: Practice across multiple states
- Locum tenens physicians: Work temporary assignments in various states
- Border-region physicians: Practice near state lines
- Health system physicians: Systems with facilities in multiple states
- Emergency/disaster response: Need rapid multi-state licensing capability
May Not Need IMLC
- Physicians practicing in a single state
- Physicians only needing licenses in California, New York, or Oregon
- Physicians with disciplinary history (may not qualify)
- Physicians without board certification and <5 years practice
Key Takeaways
- IMLC includes 42 states + DC + Guam as of January 2026
- IMLC is expedited licensure, not a multi-state license—each state issues separate licenses
- Michigan withdrawing March 28, 2026—apply before this date if you need Michigan license
- ~80% of physicians qualify based on eligibility criteria
- Application fee is ~$700 plus individual state licensing fees
- Processing time: 2-4 weeks compared to 3-6 months traditional
- California, New York, Oregon not participating
Conclusion
The Interstate Medical Licensure Compact has revolutionized multi-state medical practice, making it feasible for physicians to serve patients across state lines through telemedicine or maintain practices in multiple states. With 42 participating states covering the majority of the U.S. population, the IMLC is an essential tool for modern medical practice.
However, remember that the IMLC provides expedited access to multiple separate state licenses—not a single portable credential. Each license must be renewed according to that state's requirements, and disciplinary actions can affect all your IMLC licenses.
Use CredentialMate to track your multi-state licenses, monitor renewal dates across all your IMLC states, and ensure CME compliance in each jurisdiction—keeping your expanded practice running smoothly.
Frequently Asked Questions
Is the IMLC a multi-state medical license?
No. The IMLC is an expedited pathway to obtaining multiple separate state licenses through a single application. Each participating state still issues its own individual license, which must be renewed according to that state's requirements.
How many states participate in the IMLC?
As of January 2026, 42 states plus Washington D.C. and Guam participate in the IMLC. Notable non-participating states include California, New York, and Oregon. Michigan is withdrawing effective March 28, 2026.
How much does it cost to apply through the IMLC?
The IMLC application fee is approximately $700. In addition, you pay each state's individual licensing fee, which varies by state (ranging from ~$60 in Wisconsin to ~$1,200 in California for traditional applications).
How long does IMLC processing take?
IMLC applications typically process in 2-4 weeks for multiple state licenses, compared to 3-6 months per state through traditional applications.
What happens to my Michigan IMLC license after March 28, 2026?
If you already have a Michigan license issued through IMLC before March 28, 2026, it remains valid according to Michigan's normal renewal schedule. However, after March 28, 2026, new applicants must apply directly to Michigan rather than through the IMLC.
