Moonlighting During Residency: Rules and Visa Limits

Residents can moonlight only with written permission from their program director and within ACGME rules, and for IMGs on a J-1 or H-1B the visa adds a second, stricter layer. J-1 residents may not work outside the sponsored program and institution, with a narrow exception ECFMG describes, and H-1B work authorization is tied to the employer that filed the petition. This page explains the rules, the licensing and malpractice questions, and what to ask before taking any outside shift. It is general information, not legal advice.

What moonlighting means #

ACGME's glossary defines moonlighting as voluntary, compensated, medically related work performed beyond a resident's or fellow's clinical experience and education hours and additional to the work required to complete the program. It distinguishes two types:

• Internal moonlighting is within the institution or program's sites.
• External moonlighting is voluntary, compensated, medically related work performed outside the site of the resident's program, including the primary clinical site and participating sites.

Work required by your program, such as scheduled call or rotations, is not moonlighting.

What ACGME requires #

These are the rules as they appear in the documents we read. Programs and institutions can be stricter.

The Common Program Requirements version we read was an interim revision effective September 3, 2025. Fellowship requirements contain a parallel moonlighting section for fellows. Specialty-specific requirements and your institution's policy may add conditions, so read your own program's policy.

In practice, many programs add rules such as an annual approval, a cap on hours, a specific form or restrictions for residents in academic difficulty. That is common practice, not an ACGME rule, so ask what applies to you.

The visa layer #

This is where IMGs differ most from US graduates. Visa rules are set by the US government and sponsors, not by your program.

J-1 residents #

Intealth ECFMG's reference guide says the J-1 sponsorship documented on the DS-2019 authorizes a specific training activity and associated financial compensation. It states that federal regulations do not permit activity or compensation outside the defined parameters of the training program, and that working outside the sponsored program and institution, "moonlighting," is not permitted. The prohibition covers external opportunities outside the host institution and sponsored program, paid or unpaid.

The guide notes one change: as of September 2025, J-1 physicians may, with the approval of their program director, engage in supplemental clinical activities at their training site, with the required form submitted to Intealth by the training program liaison. Confirm the current scope on ECFMG's pages before you assume something qualifies, because we did not read the underlying form or any limits it contains. See the J-1 visa process.

H-1B residents #

An H-1B petition is filed by an employer for specific work. The regulation at 8 CFR 214.2(h)(2)(i)(C) says that if a beneficiary will perform services for, or receive training from, more than one employer, each employer must file a separate petition with USCIS. That means the hospital where you moonlight, if it is not your employer, would need to file its own H-1B petition, and some institutions will not do so for moonlighting. Whether moonlighting inside your own institution is permitted under your existing petition depends on the duties and the petition, so ask the international office. See H-1B for residents.

Other statuses #

If you hold a green card, you generally have unrestricted work authorization, and if you are a US citizen the visa issue does not arise. Other statuses have their own rules, so check before you accept work.

Licensure #

Training licenses are limited. FSMB notes that a resident or training permit lets you practice only within your residency program under supervision. Independent outside work usually needs a full, unrestricted license in that state, and the requirements for one differ by state, including Step 3 and years of training. See state licensure for IMGs and Step 3 and licensure.

Also check:

• the state where the moonlighting job is located, since you must be licensed there,
• whether the moonlighting role requires a DEA registration or hospital privileges, and
• whether your training license rules in your state restrict outside work.

Malpractice coverage #

Do not assume your residency's malpractice policy covers outside work. Ask:

• Does the program's coverage apply to this activity? We did not find a universal rule, so ask in writing.
• Does the moonlighting employer provide coverage for you, and is it occurrence-based or claims-made?
• Who pays for tail coverage if the policy is claims-made?

Other practical questions #

• Duty hours. Because moonlighting counts toward the 80-hour limit, a busy rotation may leave no room.
• Taxes and income. Outside income is taxable, and your visa and tax status can affect how. Use the IRS and a qualified tax professional. See taxes for J-1 and H-1B residents.
• Contracts. Your resident agreement may restrict outside work. Read it.
• Evaluation. Programs monitor the effect of moonlighting on performance, and adverse effects can lead to withdrawal of permission.
• Fatigue and safety. ACGME states moonlighting must not interfere with fitness for work or patient safety.

A decision checklist #

1. Check your program and institution policy. Is moonlighting allowed at all for your PGY level?
2. Ask for written program director permission.
3. Ask your international office whether your visa allows it, and in which setting.
4. Confirm licensure in the state where the work takes place.
5. Confirm malpractice coverage in writing.
6. Make sure the hours fit inside the 80-hour limit.
7. Keep records of the approvals.

If any step is unclear, do not start the work. The consequences of a status violation can last much longer than the extra income.

After residency #

Outside work rules change once you are an attending, and your employer's contract becomes the main constraint. See your first attending contract.
