Working as a travel ECMO specialist means moving across state lines constantly. In a given week, a specialist might be in Ohio, Oklahoma, and Virginia. Each state regulates healthcare practice independently, which means a clinician’s ability to legally work at each facility depends on holding the right license there. For some roles, there’s a pathway that makes this much easier, called compact licensure. For others, the pathway is still being built, or it doesn’t exist at all.

The sections below break down where compact licensure stands for the three clinical roles that make up most of travel ECMO: registered nurses, respiratory therapists, and perfusionists. Each group’s situation is different, and knowing where each one stands can help clinicians plan a travel ECMO career with fewer surprises.

Why Compact Licensure Is Such a Useful Thing to Have

A compact license is a single multistate license that lets a clinician practice in every other member state without filing a separate application. A clinician licensed through a compact who’s assigned to an account in another compact state can start covering shifts right away, with no new paperwork, state board processing time, or additional fees to clear first.

This is an especially useful advantage with traveling ECMO specialists and it changes what’s possible. Without a compact license, every new state becomes its own application cycle, which can take weeks or months and come with its own fees. For a career built on short-notice coverage across the country, that friction can add up fast.

How much of this benefit is available depends on the clinician’s role.

For Respiratory Therapists

A compact exists for RTs, but it isn’t functional yet. The Respiratory Care Interstate Compact (RCIC) officially activated in April 2026 after reaching its seven-state threshold, and as of mid-2026, roughly a dozen states have enacted it. However, the compact commission is still being stood up and individual practitioner privileges aren’t being issued yet.

In practical terms, this means RTs working as travelers today still need to pursue state-by-state licensure for every state they want to cover. Most staffing agencies, including Integration Health, will help guide RTs through this process. 

Overall, the direction of travel is toward broader mobility, but the timeline for when the RCIC becomes a working tool for traveling RTs is still uncertain.

For Perfusionists

Perfusionists don’t have a compact and there’s no multistate license for perfusion practice.

The partial upside is that not every state requires state-level perfusion licensure. Around 19 to 20 states do, and the rest treat American Board of Cardiovascular Perfusion (ABCP) certification as the credential. For states that do require a state license, each has its own application process, fees, documentation, and timelines, and perfusionists need to apply individually. For a quick visual reference, Perfusion Life maintains an interactive map that shows which states require state-level licensure and links each one to its official licensing information.

When it comes to traveling as a perfusionist, the practical path is understanding which target states require state licensure and planning for those applications in advance. As with RTs, companies like Integration Health that deploy travel perfusionists can help with the planning and application process. 

For Registered Nurses

Nursing is where compact licensure is both most established and most useful. The Nurse Licensure Compact (NLC) covers roughly 40 fully implemented states, and holding a multistate license through the compact lets a nurse practice in every other NLC state without a new application. For travel nurses, this is the single biggest practical advantage available on the licensure front.

The Primary State of Residence Requirement

The primary thing to understand is the Primary State of Residence (PSOR) requirement. The NLC is based on where a nurse legally lives, not where that nurse wants to work. PSOR is proven, in most cases, by a driver’s license. A nurse living in a compact state can apply for a multistate license through the home state’s board of nursing. 

Unfortunately, a nurse living in a non-compact state isn’t eligible for a multistate license at all, regardless of how many compact states they’d like to work in. Traveling is still possible for nurses in non-compact states, it just means applying for an individual state license in every state they want to cover.

Which States Are In the NLC

The NLC has been slowly expanding, with new states joining as their legislatures enact the compact. States that remain outside the NLC include:

• Alaska
• California
• Hawaii
• Illinois
• Michigan
• Minnesota
• Nevada
• New York
• Oregon 

Some states, like Massachusetts, have enacted the compact but haven’t fully implemented it yet. The NCSBN maintains a live map of current member states, and it’s the authoritative source to check before making any assumptions.

How to Apply for a Compact License

For eligible nurses, there are two paths to a compact license. 

• New graduates apply through their home state’s board of nursing after passing the NCLEX, and if that home state is a compact state, the license issued will be a multistate one by default. 
• Nurses already licensed in a non-compact state who move to a compact state can apply by endorsement in their new home state’s board of nursing. Endorsement means transferring the existing license into the new state and submitting a Declaration of Primary State of Residence. Once approved, the new state issues a multistate license, which allows practice in all other NLC states going forward.

Fees vary by state, and standard background checks apply.

What’s Coming

The licensure landscape is moving. Pennsylvania and Connecticut have been recent additions to the NLC, Massachusetts has enacted it without implementing it yet, and the RCIC is slowly adding states as its commission comes online. None of this moves fast, but the direction is toward broader multistate access over time. Before making decisions that depend on compact status in a specific state, clinicians should check the compact’s official site or the NCSBN directly, since the picture is constantly changing.

The Bottom Line for Travel ECMO Specialists

State licensure for traveling ECMO specialists varies depending on the role.

For nurses in compact states, the NLC is a major practical advantage, and for those who qualify, it significantly expands the accounts a specialist can cover. For nurses in non-compact states, a compact license isn’t available without a move, and state-by-state licensure becomes a standard part of travel work. 

For RTs, the compact is coming but isn’t a usable tool yet, so state-by-state licensure is the current path. For perfusionists, there’s no compact, but ABCP certification carries much of the country, and state-level licensure applies only where required.
