Step 3 and Licensure: What States Require

Step 3 is the last USMLE exam, and state medical boards generally expect all three Steps to be passed before they issue a full, unrestricted license. It is not needed to start residency. Where it gets complicated for IMGs is time limits and attempts: a board may require you to finish the sequence within a set window, and some set attempt limits that are stricter than the USMLE program's. This page explains how those rules fit together. It does not list per-state rules, which you must confirm with the board.

The time limit for finishing all three Steps #

The USMLE Common Questions page says that most medical licensing authorities require completion of Steps 1, 2 and 3 within a seven-year period, which begins when you pass your first Step. FSMB's annual report says the USMLE program recommends that state boards require the dates of passing the three Steps to fall within seven years. It also notes that this can be a problem for physicians in dual degree programs and suggests boards consider exceptions.

The recommendation is not a federal rule. FSMB's state table shows that boards differ: many use seven years, some allow longer, and some have no limit. For an IMG, the practical meaning is:

• Start your clock deliberately. The window usually begins with the first Step you pass, which for many IMGs is Step 1 or Step 2 CK, often taken years before residency.
• A delayed Step 3 can run into the limit. An IMG who passes Step 1 early and spends time on research or reapplying may find that Step 3 has to be done before residency ends.
• Ask your state. Look up the time limit for each state you might practice in.

A person who passed a Step may be allowed to retake it, with approval, if the licensing authority's time limit has expired and the authority confirms eligibility. See USMLE attempt limits and retakes.

Attempt limits: USMLE versus the state #

The USMLE program allows 4 attempts per Step. That limit applies to everyone who registers. State boards may have separate rules for licensure. FSMB's Step 3 chart shows the number of times a candidate for licensure may take Step 3 as:

• Different across boards, from a small number of attempts to no limit.
• Followed in some boards by additional training or board review after a set number of failed attempts.

A board's limit can end your path to a license in that state even if the USMLE program would still let you register. Boards may also treat attempts differently, such as counting attempts at all Steps combined. Do not treat one board's rule as a national rule. See what to do after failing a Step for the recovery side.

Residency, Step 3 and license timing #

A common sequence is: pass Steps 1 and 2 CK, match, start on a training license, take Step 3 during residency, then apply for a full license and move on to fellowship, a job or a waiver position. Our opinion: a plan works best when it is built backward from the date you need a full license, not from the date you feel ready. A job in an underserved area after a J-1 waiver, for example, normally needs a full license in that state by the start date. See J-1 waiver options.

Things that affect timing:

• Your score report time and the board's processing time.
• Whether your program has a policy about Step 3 before promotion.
• Whether your state counts preliminary or transitional years toward training requirements. See state licensure for IMGs.
• Your visa. An H-1B plan can force Step 3 earlier than licensure alone would.

How to check your state #

1. Find the board through FSMB's Contact a State Medical Board page.
2. Read the physician licensure section for IMGs and the exam rules.
3. Write down the time limit and attempt limit for Step 3, and the training years required.
4. If any answer is unclear, email the board and keep the reply.
5. Check again before you register, because boards update rules.
