The IMLC: expedited full licenses, not one super-license
Summary
The Interstate Medical Licensure Compact is an expedited route for physicians to obtain full, individual medical licenses in participating states — it is not a single license that works everywhere. You designate one member state as your principal license, receive a letter of qualification, then choose the additional states you want and pay each one's fee; every state issues its own full license. It covers physicians only; counselors, social workers, psychologists, and nurses each have their own separate compact.

What the IMLC actually is
The Interstate Medical Licensure Compact is an expedited pathway for qualifying physicians to obtain full medical licenses in member states — not a single credential that authorizes practice everywhere 1Ref 1Interstate Medical Licensure Compact Commission (2026).Interstate Medical Licensure Compact.That the IMLC is an expedited pathway to full, individual medical licenses in member states for qualifying physicians — a license per state, not one multistate license — via a State of Principal License and Letter of Qualification.. The common misread is that it works like a driver's license honored across state lines. It does not. What you receive is a separate, full, unrestricted license from each member state you select, issued faster because your credentials were verified once at the front of the process. Every one of those licenses is a real state license, with that state's fee, renewal, and rules attached.
That distinction matters for telehealth because your authority to treat follows the patient's location, not yours. If you want to see patients in five member states, the IMLC gives you a faster route to five licenses — it does not collapse them into one. The compact map is worth studying before you count on it, since only member states participate and membership changes over time.
Why you need it: licensure follows the patient
The reason cross-state licensure is a live problem for a solo physician is the rule underneath all of telehealth: you must be licensed where the patient is physically located at the time of the visit, with compacts and a few state registration pathways as the exceptions 2Ref 2U.S. Department of Health and Human Services (2026).Licensure — Telehealth policy.That telehealth licensure follows the state where the patient is located at the time of service, with compacts and state registration pathways as the exceptions — the reason a physician needs licensure in each patient's state.. A patient who moves, travels, or simply lives across a nearby border can pull a visit into a state where you hold no license, and treating them there without one is practicing medicine without a license in that state.
The IMLC exists to make it feasible to hold licenses in several states without running the full, slow application in each one separately. For a physician building a telehealth panel that crosses state lines, it turns a stack of independent, months-long applications into one qualification step followed by faster per-state issuance. It solves the volume-and-speed problem; it does not change the underlying rule that each state's authority is its own.
How the pathway works, step by step
The process runs through a single designated state and then fans out. You pick one member state as your State of Principal License — generally where you hold a full license and have your primary connection — and apply through the compact there. That state verifies your eligibility and, if you qualify, issues a Letter of Qualification. With that letter in hand, you select the additional member states where you want licensure and pay each state's fee, and each issues its own full license 1Ref 1Interstate Medical Licensure Compact Commission (2026).Interstate Medical Licensure Compact.That the IMLC is an expedited pathway to full, individual medical licenses in member states for qualifying physicians — a license per state, not one multistate license — via a State of Principal License and Letter of Qualification..
- Designate your State of Principal License. This is your home base in the compact and where moving your home state would restart the qualification.
- Obtain the Letter of Qualification. Your principal state verifies credentials once for the compact.
- Select target states and pay their fees. You choose which member states, and each charges its own license fee.
- Receive a full license from each. Every selected state issues a genuine, independent license, faster than a standalone application.
After issuance, each license is yours to maintain, so compact maintenance means keeping every one current on its own schedule.
Who qualifies — and who the IMLC leaves out
The IMLC is for physicians — MDs and DOs — who meet a defined eligibility bar, typically an unrestricted license in good standing, graduation from an accredited school, passage of the licensing examinations, and a clean disciplinary and background record 1Ref 1Interstate Medical Licensure Compact Commission (2026).Interstate Medical Licensure Compact.That the IMLC is an expedited pathway to full, individual medical licenses in member states for qualifying physicians — a license per state, not one multistate license — via a State of Principal License and Letter of Qualification.. If you clear the criteria, the expedited pathway is open; if you do not, you fall back to standard, state-by-state application. A prior board action or a restriction on a license commonly takes a physician out of the expedited lane.
Just as important is who the compact does not serve. The IMLC is a physician mechanism only. It does nothing for therapists, counselors, clinical social workers, psychologists, or nurse practitioners — a lapsed license or a missing license in a state you are treating into is not cured by the IMLC unless you are a physician using it. Each of the other professions has its own separate arrangement, which is where a non-physician clinician should look instead.
If you're not a physician: your compact instead
Behavioral-health clinicians who are not physicians have their own compacts, and each works on its own terms — some issue a privilege to practice across member states rather than a license per state, which is a different mechanism from the IMLC. Match your profession to the right one rather than assuming any single compact covers you. For a psychiatric nurse practitioner, note that the nurse compact addresses the underlying RN license, while advanced-practice authority is handled separately and more narrowly.
| Your profession | The compact to look at |
|---|---|
| Physician (MD/DO) | Interstate Medical Licensure Compact |
| Psychologist | PSYPACT 3Ref 3PSYPACT Commission (2026).PSYPACT.That PSYPACT authorizes qualifying psychologists to practice telepsychology across member states as a practice privilege — the psychologist counterpart to the IMLC. |
| Licensed professional counselor | Counseling Compact 4Ref 4Counseling Compact Commission (2026).Counseling Compact.That the Counseling Compact grants licensed professional counselors a privilege to practice across member states — the counselor counterpart to the IMLC — with implementation ongoing. |
| Clinical social worker | Social Work Licensure Compact 5Ref 5Social Work Licensure Compact (2026).Social Work Licensure Compact.That the Social Work Licensure Compact creates multistate practice privileges for eligible social workers as states implement it — the social-work counterpart to the IMLC. |
| Registered nurse (incl. a PMHNP's RN layer) | Nurse Licensure Compact 6Ref 6National Council of State Boards of Nursing (2026).NURSECOMPACT — Nurse Licensure Compact.That the Nurse Licensure Compact lets RNs/LPNs hold one multistate license honored in member states, relevant to a PMHNP's underlying RN licensure layer. |
The social work compact and the counseling compact are still standing up their operational details as member states implement, so confirm current status before you rely on either. How PSYPACT authority actually works differs from the IMLC in that it grants a practice privilege for telepsychology rather than a stack of individual state licenses.
What the IMLC does not do
It helps to name the compact's limits so you do not lean on it for things it never covered. The IMLC does not create a single national license, does not waive each state's separate licensing fee, and does not exempt you from each state's practice rules once licensed. It also does not touch your federal DEA registration or any state controlled-substance registration — those are a separate track you handle state by state on their own timelines.
And it does not maintain your licenses for you. Once issued, each state license renews on its own schedule and can lapse independently, so the administrative load scales with the number of states you hold. Before opting in, weigh the expedited-issuance benefit against the ongoing cost and upkeep of every license you acquire — the compact speeds the front door, but the maintenance is yours for as long as you keep each license.
