State Medical License Guide
Which board licenses you, where the application actually lives, which documents to gather, and whether the compacts can speed up your next states — for physicians and nurse practitioners, all 50 states.
Every US medical license is issued by a state, for a profession — never by specialty. A cardiologist and a family physician in Texas are licensed by the same Texas Medical Board; what differs is their board certification. This guide gives you, for all 50 states, the board that licenses physicians (MD/DO) and nurse practitioners (APRN), the official place to apply, the compact status that decides how fast extra states can follow, and the documents boards ask for. Board links and names were verified against official board sources in October 2026.

Initial license vs endorsement — what is the difference?
An initial license is for someone who has never held the license: a new graduate, or a clinician licensing in their profession for the first time. The board verifies everything from primary sources — school, exams, training. Licensure by endorsement is how an already-licensed clinician gets licensed in an additional state: the new state does not simply transfer or recognize the old license — it issues its own license, but it verifies your existing license directly with the state that issued it instead of treating you as a new graduate. Physicians' verifications usually travel through the FSMB's FCVS or board-to-board letters; nurses' travel through Nursys, the national nurse-license database run by NCSBN. Three things surprise applicants:
- Endorsement is not automatic. You must meet the new state's own requirements; if your education or exam pathway would not qualify there today, the board can ask for more — or decline endorsement.
- Every state you have ever held a license in gets verified, not just the current one, and education/exam documents often still go primary-source.
- The compacts can replace the slow route. If both your current state and your target state are in the IMLC (physicians) your endorsement can run on the compact's expedited track; for nurses, a multistate NLC license already covers the RN side in every compact state, leaving only the APRN authorization to apply for. Pick "Endorsement" in the finder above and it works out which of these applies to your two states.
The usual procedure — physicians
- Confirm the basics: a medical degree (MD or DO), USMLE or COMLEX-USA passed, and residency completed — most states require one to three years of accredited graduate medical education, and some require more on international-graduate pathways.
- Open an FCVS profile (the FSMB's credentials verification service) if your board accepts or requires it — many do. It primary-source-verifies your core credentials once, and every later state application reuses them.
- Apply on the board's portal (button above) and pay the application fee. Answer every disclosure question completely — partial answers are the most common cause of deficiency letters.
- Complete the background check the board specifies (usually fingerprint-based, state + FBI).
- Have documents sent directly from their sources: medical school, exam bodies, residency programs, and every state where you have ever held a license.
- Finish state-specific extras (for example, Texas requires its Medical Jurisprudence exam) and answer any deficiency notice quickly — files wait on applicants far more often than on boards.
- After the license issues: DEA registration if you will prescribe controlled substances, then payer enrollment, CAQH and credentialing before you bill under it.
Documents physicians are typically asked for
- Government photo ID and proof of legal work authorization
- Medical school diploma and transcript (primary-source verified)
- USMLE or COMLEX-USA score transcript
- Residency and fellowship completion certificates and program verifications
- ECFMG certificate (international medical graduates)
- Verification of every license ever held in another state
- Malpractice history and, where requested, an NPDB self-query report
- A complete CV — all training and practice since graduation, with gaps explained
- Fingerprint cards / background-check consent forms
- Specialty board certification — not required for the license itself, but required for IMLC eligibility and most hospital and payer credentialing
The usual procedure — nurse practitioners
- Hold an RN license — if your home state issues a multistate (NLC) license, it already covers RN practice in every compact state.
- Complete a graduate APRN program (MSN or DNP) in your role and population focus — family, adult-gerontology, pediatrics, psychiatric-mental health and the other recognized foci.
- Pass the national certification exam for your focus (ANCC, AANP, PNCB, NCC or AACN, depending on role) — the board will require the certifying body to verify it directly.
- Apply to the state board of nursing for APRN licensure or authorization (button above), with transcripts and certification verification sent from their sources.
- Complete fingerprinting and the background check.
- Sort out prescriptive authority: some states include it in the APRN license, some require a separate application, and reduced/restricted-practice states require a collaborative or supervisory agreement with a physician to be in place.
- After licensure: DEA registration if prescribing controlled substances, then payer enrollment and CAQH before billing.
Documents nurse practitioners are typically asked for
- Current RN license (multistate, if you hold one)
- Graduate nursing transcript, sent directly by the school
- National certification verification, sent by the certifying body
- Graduate degree diploma
- Government photo ID
- Fingerprint / background-check consent
- Collaborative or supervisory agreement documentation (states that require one)
- Prescriptive-authority application and proof of advanced pharmacology coursework (where the state handles it separately)
APRN roles and nurse practitioner specialties
APRN (Advanced Practice Registered Nurse) is the umbrella license category, and it has four roles — all licensed by the state board of nursing in almost every state:
- Nurse Practitioner (NP) — the largest role: direct primary and specialty care for a defined patient population.
- Clinical Nurse Specialist (CNS) — expert clinician in a specialty area, often combining direct care with systems and education work. Most states license CNSs as APRNs; a few do not — check your board.
- Certified Nurse-Midwife (CNM) — pregnancy, birth and women's health, certified by the AMCB; licensed through the board of nursing in most states, though a few states route midwifery through a different board.
- Certified Registered Nurse Anesthetist (CRNA) — anesthesia care, certified by the NBCRNA; state rules on supervision and independent practice vary more for this role than for any other.
Within the NP role, your specialty is your population focus — family (FNP), adult-gerontology (AGPCNP / AGACNP), pediatrics (PNP), women's health (WHNP), neonatal (NNP), emergency (ENP), and psychiatric-mental health (PMHNP). A focus is not a preference: your graduate program, your national certification exam and the patients you may legally treat all follow it — practicing outside your certified population is outside your scope in most states. One clarification that matters: a PMHNP is not a psychiatrist. A psychiatrist is a physician (MD/DO) who completed a psychiatry residency and certifies through the American Board of Psychiatry and Neurology. The PMHNP is the nursing route into psychiatric care — assessing, diagnosing and treating mental-health conditions, including prescribing, under the APRN rules of the state. Physicians pick their specialty the same structural way: the license is identical, and the specialty (psychiatry, cardiology, family medicine…) comes from residency plus ABMS or AOA board certification.
License, specialty, and compacts — three different things
State license (this guide) is the legal permission to practice, issued by the state board. Specialty certification is separate: physicians certify through ABMS or AOA member boards, and nurse practitioners through their national certifying bodies — employers, hospitals and payers require it, but it is not the license. Compacts are the shortcut for multi-state practice: the IMLC gives eligible physicians an expedited route to a full license in each member state (you still hold one license per state), while the NLC makes one RN license valid across all compact states — APRN authorization itself is still granted state by state. If licensing across several states is on your desk, our licensing services team runs applications end to end, and pairs them with credentialing and payer enrollment so a new license turns into billable practice without a gap. The calendar side — CAQH and revalidation dates — is covered by our credentialing date calculator.
Boards change fees, forms and requirements. This guide is a starting map, verified from official board sources in October 2026 — the board's own current checklist is the authority before you apply.
Frequently asked questions
Does my specialty change which board licenses me?
No. State boards license by profession, not specialty: every MD and DO in a state answers to the same medical board (a few states run a separate osteopathic board), and every APRN to the board of nursing. Specialty enters through board certification — ABMS or AOA boards for physicians, national certifying bodies for nurse practitioners — which employers, hospitals and payers require, but which is not the license itself.
How long does a state medical license take?
It varies widely by board and by how complete the file is — from several weeks to several months. The controllable part is document readiness: applications stall on missing transcripts, slow license verifications from other states, and unanswered deficiency notices. Applying with primary-source documents already moving, and answering board queries within days, is what separates the fast files from the slow ones.
What is the fastest way to get licensed in several states?
For physicians, the IMLC: if you hold an unrestricted license in a member state that serves as your state of principal license, meet its eligibility rules (including board certification and a clean history), the compact verifies you once and member states issue full licenses on an expedited basis. For nurses, an NLC multistate RN license covers RN practice in all compact states — but APRN authorization is still applied for state by state.
What does licensure by endorsement mean, and how is my old license verified?
Endorsement is how an already-licensed clinician gains a license in an additional state: the new board issues its own license but verifies your existing one directly with the issuing state instead of treating you as a new graduate. Physician verifications typically run through the FSMB's FCVS or board-to-board letters; nurse verifications run through Nursys, the NCSBN's national license database. Every state you have ever been licensed in is verified, and you must still meet the new state's current requirements.
