The Interstate Medical Licensure Compact, generally known as the IMLC, is an agreement among a large group of participating states designed to make it faster for eligible physicians to obtain a medical license in more than one state. It does not create a single national license. Instead, it creates an expedited pathway that runs alongside each state's existing licensing process.
What the compact actually does
A physician who qualifies under the IMLC selects a "state of principal license," which serves as the basis for review. That state verifies the physician's credentials and issues a Letter of Qualification confirming eligibility. The physician can then use that letter to apply for licensure in any number of other member states, typically with a faster turnaround than a standalone application in each state would take.
Who tends to qualify
Eligibility generally depends on factors such as holding an unrestricted medical license, having no history of significant disciplinary action, and meeting certain training and board certification benchmarks. Physicians who practice primarily in one specialty, or whose training does not fit the typical pathway, may find that eligibility requires a closer look at their specific history. Because criteria can shift and vary in application, it is worth reviewing current eligibility standards directly rather than assuming past qualification still applies.
The IMLC speeds up the paperwork of getting licensed in multiple states — it does not replace the need for a separate license, or separate compliance, in each one.
What the compact does not change
Even after a physician receives a license through the IMLC pathway in a new state, that license is a full license issued by that state's medical board, subject to that state's own renewal cycle, continuing education rules, and scope-of-practice standards. Controlled-substance prescribing, telehealth-specific rules, and DEA registration are handled separately and are not automatically resolved by IMLC participation. Many physicians pursuing multistate practice, particularly through telehealth, use the compact as one part of a broader licensure strategy rather than a complete solution on its own.
Physicians considering the IMLC pathway generally benefit from mapping out which states they intend to practice in and confirming each state's current participation status and requirements early in the process. Requirements vary by state and change over time — always confirm current requirements directly with the relevant state board or agency before making a compliance decision.
