Not automatically, and usually not the certificate itself. The US has no national trades authority and no federal system that converts a foreign license into an American one. Every recognition decision is made by the individual state licensing board where you plan to work, and what those boards usually care about is your documented work experience, not the certificate that came with it. Your City & Guilds, NVQ, ITI, TESDA, CONOCER, or Red Seal paperwork is respected as evidence of what you can do, but it does not waive a state's exam or experience rules. A small handful of federal or industry-wide credentials do travel with you, and it is worth sitting those first.
There is no federal recognition, so the first question is always "which state?"
Unlike Canada, where the Red Seal program creates one national benchmark, the US pushes every credentialing decision down to the states. There is no Red Seal equivalent, no federal trades registry, and no single body that compares a foreign certificate to an American one. The US Department of Education says so plainly: regulated trades are licensed at the state level, and the competent authority for recognizing your prior training is the state licensing board where you intend to work. The Department itself does not evaluate foreign qualifications.
So a gas engineer from Dublin, an ITI graduate from Gujarat, and a Red Seal electrician from Manitoba all hit the same first question when they land: which state am I moving to? The board in that state, not Washington, decides whether your experience counts and whether you have to re-qualify. Because the specifics (how many years, whether foreign hours count at all, which exam) vary enormously, this guide teaches the pattern and routes the numbers to Working in Your State.
The hours are the currency, the certificate is the evidence
Here is the mental shift that saves people the most grief. In most trade contexts, your overseas qualification does not "transfer" as a document. What state boards typically want to see is documented work experience measured in hours and years. The certificate is proof that you were trained. The hours behind it are what actually count toward exam eligibility.
- Some boards accept documented foreign hours toward the experience you need to sit their exam. A former overseas employer or supervisor can be the person who verifies those hours, as long as the documentation is credible.
- Other boards discount or refuse foreign hours, counting only time worked under a US-licensed tradesperson or an approved US apprenticeship. Which camp your state falls into is a per-state question for the board.
- The board's own application form is the master key. Boards that accept foreign hours will ask for a signed statement from your overseas employer, on company letterhead, confirming your job title, employment dates, duties, and hours worked per week. Notarization is sometimes required.
The practical trap: if your state wants several years of journey-level experience and your only paperwork is a completion certificate from a one or two year program, the certificate alone carries little weight at the licensing desk. You may need additional US working time before you can test. Plan for that in your timeline, not on arrival.
The credentials that actually port across the US
There is a small category of near-national credentials that genuinely travel, because they are either federally required or industry-wide in acceptance. None of them is a substitute for a state license, but they cut down redundant re-testing and signal competence to employers, so sit them early.
EPA Section 608 (HVAC and refrigeration): the one that matters most. Under Section 608 of the Clean Air Act, anyone who services, repairs, or disposes of equipment containing regulated refrigerant must hold EPA 608 certification. In 2026 this is a federal requirement, not a state one, so it applies everywhere. There are four types (Type I for small appliances, Type II for high-pressure, Type III for low-pressure, and Universal for all three). You do not need any prior US experience or a state license to sit the exam, and once earned the certification never expires. If you work in HVAC or refrigeration, this is the very first credential to get, and you can even study for it before you move. Verify current rules at epa.gov/section608.
NATE (HVAC): respected, not a license. North American Technician Excellence is the largest independent HVAC/R credentialing standard, and while it does not let you pull a permit or contract on its own, employers, utilities, and manufacturers value it. You pass a Core exam plus one or more specialty exams. In 2026 the professional-level certification is valid for two years and needs 16 continuing education hours to recertify (or a re-exam). At least a dozen states also accept NATE continuing education toward state license-renewal hours. For a newly arrived HVAC tech, EPA 608 (required) plus NATE (respected) is the strongest opening package.
ICC code certifications: for inspection and code-compliance roles. The International Code Council offers certifications in building inspection, plan review, and code enforcement. They travel well because most states have adopted some version of the ICC model codes (IBC, IRC, and related). In 2026 they are valid for three years and need 1.5 CEUs (15 hours) to renew, and the exams are open-book and can be taken online. Important limit: an ICC certification does not replace a state plumbing, electrical, or HVAC contractor license. It is most useful if you are moving toward inspection or plan-review work rather than hands-on contracting.
OSHA 10 and OSHA 30: safety cards, not licenses. These are portable across the country, and several states require them on public works projects. Many larger employers now ask for them as a condition of hire regardless of state law, so they are cheap insurance for getting on site. They do expire in most states that mandate them, typically on a five-year cycle. Whether your specific project or state requires one is a per-state and per-contract question, so route it to Working in Your State.
State occupational licenses do NOT port. An electrician's license from one state, a master plumber's license from another, a contractor's license from a third: none of these automatically carries into a new state. Some states have narrow reciprocity with specific neighbors, but reciprocity is state-to-state and trade-to-trade, and an overseas license receives zero formal statutory recognition anywhere in the US.
What this means by where you trained
The honest summary for every origin is the same: respected, but not recognized. Your training is useful as evidence of competence and as the raw material for documenting hours, but no US board treats it as license-equivalent.
- UK and Ireland (City & Guilds, NVQ Level 3, SVQ, Irish NFQ Level 6). Strong, structured credentials that employers respect. The documented hours of a UK or Irish apprenticeship can be submitted as evidence of journey-level experience, and many boards accept them if properly documented. You still sit the state exam. There is no US equivalent to Gas Safe or ACS registration; US gas work sits under state plumbing or HVAC licensing, so a Gas Safe engineer re-qualifies under the destination state's regime. The competency is directly relevant. The certificate is not a license.
- India (ITI / NCVT National Trade Certificate). Recognized across India but not by any US board. The common challenge is that a one or two year ITI program is shorter than the experience most US states want, which creates a gap. Post-qualification working years can be documented toward exam eligibility. A credential evaluation can translate the diploma into a US educational equivalent for employers, though boards are not bound by it.
- Philippines (TESDA NC II / NC III) and Mexico (CONOCER). Widely used at home and for deployment elsewhere, but with no bilateral recognition in the US. The documented work experience behind the certificate is the asset. You qualify under destination-state rules like everyone else.
- Canada (Red Seal). The closest thing to a transferable standard in North America and genuinely respected by US employers, especially on large commercial and unionized projects. But it still does not automatically transfer to any US state, and there is no US-Canada trade-license treaty. Some unionized contractors have informal pathways to bring a Red Seal journeyperson in at journeyperson level, but that is an employment arrangement, not a licensing equivalency. You still sit the state exam.
A note on a moving target: proof of lawful presence
Recognition of your skills is one question. Whether you are allowed to hold the license, and to be employed, is a separate one that depends on your immigration status and your state. As one example of how fast this area moves, Texas began requiring proof of lawful presence for TDLR-regulated licenses (electricians and HVAC among them; Texas plumbers are licensed by the separate state plumbing board) in 2026. Rules like this change with each legislative session and each administration, so treat any status-and-licensing specific as a live question for an immigration attorney and the state board, not something to assume from a web page.
The "before you move" credential prep that pays off
These steps cost little and make a real difference at the licensing desk. Do them before you leave.
- Identify the exact state board for your trade (electrical, plumbing, HVAC, and general contracting are often separate boards) and download its current application form now.
- Get employer reference letters for every job, on company letterhead, showing your name, job title, start and end dates, hours per week, and duties. Have a supervisor or HR sign, and notarize if you can.
- Total up your documented hours honestly. US boards may not count supervisory or management time the same as hands-on hours.
- Get certified English translations of any non-English certificate, with the original attached.
- Commission a credential evaluation from a reputable NACES-member service if your board asks for one. Expect a modest fee, and use only recognized evaluators, not a "consultant" who guarantees an outcome.
- Sit EPA 608 before arrival if you are HVAC or refrigeration. You can take it anywhere and it never expires.
- Sort your Social Security Number quickly once you have work authorization, because many license applications require one. See the SSN and ITIN guide.
Common questions
Does my City and Guilds, NVQ, ITI, TESDA, or Red Seal qualification transfer to the US?
No US state automatically recognizes a foreign trade qualification as license-equivalent. Your certificate is respected as evidence of competence, but you still have to qualify under the destination state's rules, which usually means passing that state's exam. What often does count is the documented work experience behind the certificate. Boards that accept foreign hours want employer letters on letterhead showing your dates, duties, and hours per week. How many years count, and whether foreign hours count at all, varies by state, so check Working in Your State.
Which certifications actually work in every US state?
A few travel nationally. EPA Section 608 is federally required for anyone handling refrigerant and never expires. OSHA 10 and OSHA 30 safety cards are portable and often required on site. NATE (HVAC) and ICC code certifications are widely respected industry credentials. None of these replaces a state contractor or trade license, but they reduce re-testing and help you get hired. In 2026, EPA 608 is the single most valuable one to sit first if you are in HVAC or refrigeration. Verify current requirements at epa.gov and osha.gov.
Do I need a credential evaluation like WES, and does it get me licensed?
A credential evaluation from a recognized NACES-member service maps your foreign qualification to a US educational equivalent, which helps with employers and is required or recommended by some state boards. But it does not license you, and boards are not bound by the report. It is a useful document, not a shortcut around the exam. Use only established, recognized evaluators. Anyone who "guarantees" a license or a specific evaluation result in exchange for a fee is a warning sign, not a service.
Can I sit the EPA 608 exam before I even arrive in the US?
Yes. EPA 608 has no prior-US-experience or state-license requirement, prep materials are widely available, and the exam is offered by EPA-approved organizations. In 2026 it is a federal requirement for refrigerant work and the certification is permanent once earned. For an HVAC or refrigeration worker it is the most efficient credential to have in hand on day one. Whether your state then requires a separate HVAC contractor license on top is a state question. Verify current EPA rules at epa.gov/section608.
The honest bit
- This is general information about how US credentialing works, not legal or immigration advice. Whether you can hold a license or be employed depends on your immigration status, which is a matter for a licensed immigration attorney (find one through aila.org) or a DOJ/EOIR-recognized accredited nonprofit, never a notario or unlicensed "consultant."
- Federal certifications named here (EPA 608, and the OSHA card programs) are current for 2026. Verify EPA 608 at epa.gov, OSHA cards at osha.gov, NATE at natex.org, and ICC at iccsafe.org before relying on any detail.
- How many years of experience your state requires, whether it counts foreign hours, and which exam you sit are all per-state decisions. Route them to Working in Your State and the relevant board, and confirm on the board's current application form.
- Beware credential and licensing scams: anyone charging you to "guarantee" recognition, a license, or an evaluation result, or asking for payment by gift card, wire, or crypto, is running a fraud. Government forms and most board applications are free at the source.
