US State Medical Licensing for IMGs: The Variation Map: IMG guide for UK practice (2026)

Key points

US medical licensing is <strong>state-by-state</strong> — there is no single national licence.
States differ on: training duration requirements, Step 3 timing rules, and acceptance of international training.
Check FSMB for your target state's specific requirements <strong>before</strong> you commit to a geographic plan.

Unlike most countries, the US does not have a single national medical licence. Each state medical board sets its own rules for licensure, and these rules vary significantly for IMGs. Some states require completion of a full residency before granting a licence; others allow practice under training permits or limited licences. Some require all three USMLE Steps before licensure; others allow Step 3 to be taken during residency. Understanding these differences is critical for career planning.

Step 1 — Identify your target state(s)

Your residency location determines your initial state licence. If you have flexibility (e.g., applying broadly), consider which states have licensing requirements compatible with your timeline. The FSMB maintains a database of state medical board requirements.

Step 2 — Check training duration requirements

Most states require at least 2–3 years of accredited postgraduate training (ACGME or equivalent) for full medical licensure. Some states accept 1 year (PGY-1) for a limited licence. If you plan to practice independently after a short training period, verify that your target state allows it.

Step 3 — Verify Step 3 timing rules

Some states allow IMGs to take Step 3 without any US postgraduate training. Others require completion of PGY-1 or even PGY-2 before sitting Step 3. This matters for H-1B visa planning — if you need Step 3 before residency, you must find a state that allows early testing.

Step 4 — Check WDOMS and medical school recognition

A small number of states have additional requirements beyond ECFMG certification, such as specific accreditation standards for your medical school. Most states accept ECFMG certification as sufficient verification, but verify directly with the relevant state medical board.

Step 5 — Plan for post-residency licensure

If you plan to practice in a different state after residency, check that state's licensing requirements before you start. Some states require additional documentation or training duration that is easier to satisfy during residency than retrospectively.

FSMB is your primary resource

The Federation of State Medical Boards (FSMB) maintains detailed information on each state's licensing requirements. Their website allows you to compare requirements across states. Use it as your primary reference — do not rely on forum posts or outdated guides.
