If you're an LCSW seeing clients across state lines, one compact does most of the work for you — but only in the states where it applies. Here's how to know which states those are, and what to do about the rest.
As an LCSW, LICSW, LISW, LISW-CP, LISW-S, or LMSW, the compact that matters to you is the ASWB Mobility Compact (sometimes called the Social Work Licensure Compact). If your home state and your client's state are both members, you can generally practice there under compact privilege instead of getting a second full license. If either state isn't a member, the compact doesn't help — you need a direct license in that state, or the session isn't authorized.
That's the whole concept in two sentences. The part that actually trips people up is the second one: compact membership is not universal, and it's not permanent. A state that wasn't a member last year might be now. One that was a member might have changed its implementation status. Working from a list you checked six months ago is how compliant-seeming providers end up with a real gap.
The Social Work Licensure Compact is newer than compacts like the Interstate Medical Licensure Compact (which covers MDs and DOs) or PSYPACT (psychologists) — and newer compacts tend to still be actively adding member states as more state legislatures pass the enabling legislation and boards finish implementation. That's good news long-term — broader coverage is coming — but it means the list of member states you learned when you first checked is more likely to be out of date than it would be for a longer-established compact.
Two separate things can change independently: a state can pass compact legislation but not yet be issuing privileges under it, and a state that's fully live can still have credential-specific carve-outs. Neither shows up if you're working from memory or an old screenshot.
TeleVerify maintains a live compliance page for every U.S. state, D.C., and Puerto Rico, each showing current ASWB Mobility Compact membership status alongside the state's consent, prescribing (where applicable), and board-standard rules for LCSWs specifically. A few examples:
For the compact itself — who's eligible, how the privilege application works, current fees and processing time — see the ASWB Mobility Compact page. It's worth reading in full before you apply, since (like every compact) the privilege is tied to your home-state license: if that license is disciplined or lapses, the privilege goes with it in every member state simultaneously.
If your client is located in a state that isn't an ASWB member — or your home state isn't eligible to be your compact "home" state under the compact's rules — the compact provides no coverage for that session. Your options are a direct license in that state, a state-specific telehealth registration pathway if one exists (some states offer these as a lighter-weight alternative to full licensure; check the state's compliance page for a "state registration program" section), or not seeing that client until one of those is in place.
This is also where credential naming gets people. "LCSW" isn't used identically in every state — some states use LICSW, LISW, LISW-CP, or LISW-S for what is functionally the same credential tier. The compact and each state's board rules generally track the underlying licensure category, not the exact letters on your license, but it's worth confirming rather than assuming if your credential abbreviation is unusual.
For one or two out-of-state clients, checking each state's page before your first session with them is manageable. If you're building a caseload across a dozen states, or you're part of a group practice with LCSWs licensed in different home states seeing clients across a shared, wider footprint, manual checking gets error-prone fast — and it's exactly the kind of gap an insurer audit or a licensing board complaint surfaces after the fact, not before.
