The national interest waiver asks three questions. Most petitions die on the second one.

Each prong mapped to what actually satisfies it. Every row is sourced in the list at the foot of this page.
Prong	What satisfies it
Prong one — substantial merit and national importance	Evidence about the work, not about you. Merit can be shown in business, entrepreneurship, science, technology, culture, health or education. Merit may be established without immediate or quantifiable economic impact. National importance turns on the prospective impact and the nature of the endeavour, not on its geographic breadth — a locally or regionally focused endeavour can qualify.
Prong one — what does not satisfy it	A job title, a degree, a company name, or a restatement of what the occupation normally involves. The endeavour must be more specific than the general occupation: in Dhanasar itself the occupation was engineer and the endeavour was research and development on air and space propulsion systems.
Prong two — well positioned to advance the endeavour	Evidence about you. USCIS weighs education, skills, knowledge and record of success in related or similar efforts; a detailed proposal or plan for future activities, developed by you or with you in a significant role; progress already made toward the endeavour; and interest from potential customers, users, investors or other relevant entities.
Prong two — what does not satisfy it	A strong record in a different line of work. The record has to translate. Strong petitions state how past success predicts the proposed plan and name the steps already taken toward it.
Prong three — on balance, the waiver benefits the United States	A balancing finding, not a fourth merit test. USCIS considers whether it would be impractical to obtain a labour certification given your qualifications or endeavour; whether the United States benefits from your contributions even if other US workers were also available; and whether the national interest is sufficiently urgent to warrant forgoing the process, such as a time-sensitive public health or safety benefit.
What no prong requires	A job offer, an employer, or a labour certification — the waiver is a waiver of both. Nor is there a requirement that the endeavour succeed: many innovations and entrepreneurial endeavours ultimately fail despite an intelligent plan and competent execution, and the petition is not required to show that the endeavour is more likely than not to succeed on the usual metrics.

The short version

A national interest waiver is a discretionary benefit. USCIS may grant it if you demonstrate eligibility by a preponderance of the evidence across three findings: that your proposed endeavour has both substantial merit and national importance; that you are well positioned to advance that endeavour; and that on balance it would benefit the United States to waive the job offer and therefore the permanent labour certification requirement. Those three sentences are the whole test. Everything else is how officers are told to apply them.

The three are not alternatives and they do not add up. They are cumulative, and each is assessed on the whole record. A petition that proves an important field, a competent person and a plausible benefit can still be denied because prong two was never argued: nothing in the file showed why this particular person was the one positioned to advance this particular piece of work.

Prong one is about the work. Prong two is about you. Prong three is a balance between the value of waiving the labour market test and the value of keeping it. Officers are told they cannot treat prong three as a formality to be paid off once prongs one and two are satisfied, and they cannot treat prongs one and two as one combined enquiry into whether you seem impressive.

The single most common structural failure is a petition whose endeavour is too coarse to be judged. An endeavour is more specific than an occupation. If the petition describes the field as machine learning, or oncology, or financial technology, there is no question an officer can actually answer — you cannot be shown to be well positioned to advance an entire discipline, and no discipline as a whole has a prospective impact that a single person advances. The description has to name the work.

The second most common failure is arguing merit and importance with the wrong evidence. Prong one is not satisfied by your credentials, your employer's reputation, or the fact that your field is important. It is satisfied by what the proposed work will do and who it will affect, described in terms an average person can follow.

The test it replaced, and what the replacement changed

Before 2016 the governing framework was Matter of New York State Dept. of Transportation, 22 I&N Dec. 215 (Acting Assoc. Comm'r 1998) — the NYSDOT test. It asked whether the person sought employment in an area of substantial intrinsic merit, whether the proposed benefit would be national in scope, and whether the national interest would be adversely affected if a labour certification were required. In practice the second element was read as a geographic test, and the first as a question about the field rather than the work.

Matter of Dhanasar, 26 I&N Dec. 884 (AAO 2016), withdrew NYSDOT and replaced the three elements with the three prongs in use today. The change that matters most is the shift from an area of employment to a proposed endeavour. NYSDOT asked what field you work in. Dhanasar asks what you propose to do, then asks what impact that specific proposal would have. The AAO also dropped the geographic framing: it found that certain locally or regionally focused endeavours may be of national importance despite being difficult to quantify with respect to geographic scope.

A second change is that Dhanasar made the test expressly discretionary and additive across prongs rather than a set of independent gates. Officers assess each prong on a case-by-case basis. The more integral a person is to an endeavour, the stronger the case that they are well positioned to advance it — which makes the strength of prong two a function of how tightly the endeavour is defined, and therefore partly a drafting question.

The practical consequence of the replacement is that the phrase national interest no longer carries the weight it once appeared to. What carries the weight is national importance — a term the AAO and USCIS have given defined content, described through the prospective impact of a specific endeavour rather than through the geographic reach of a career or the size of the field.

Prong one: substantial merit and national importance

Merit is the easier half, and it is not about money

USCIS directs officers to consider whether the evidence demonstrates merit and importance by a preponderance of the evidence. Merit may be demonstrated in areas including, but not limited to, business, entrepreneurship, science, technology, culture, health or education. Critically, merit may be established without immediate or quantifiable economic impact, and the guidance says so in terms — a petition does not need revenue projections to clear this half of the prong. Endeavours whose merit rests on cultural, artistic or scholarly value are expressly contemplated.

National importance means prospective impact, not geography

Officers are told to examine the national importance of the specific endeavour proposed by considering its potential prospective impact, and to focus on the nature of the endeavour rather than only its geographic breadth. The example given is that an endeavour may have national importance because it has national or even global implications within a particular field, such as certain improved manufacturing processes or medical advances. Economically, it may have significant potential to employ US workers at a level significant relative to the population and economic circumstances of the relevant area.

The four ways importance gets established

The guidance gives officers four lenses. National or global implications within a particular field. Significant potential to employ US workers. A significant positive economic effect, particularly in an economically depressed area. And significant potential to broadly enhance societal welfare or cultural or artistic enrichment, or to contribute to the advancement of a valuable technology or field of study. That last lens is the one that carries petitions outside STEM, and it is broader than most applicants assume.

Where prong one is actually lost

Three patterns. The endeavour is stated as an occupation, so there is nothing whose impact can be assessed. The impact is asserted rather than evidenced, with a plan and a field but no indication of who is affected or how. Or the evidence proves the employer's importance — a famous laboratory, a well-covered institution — while the endeavour as proposed is something any competent engineer in that institution could do. Prong one is where the field and the plan are tested. It is not where your CV is tested.

Prong two: well positioned to advance the endeavour

The prong that centres on the person

Unlike prong one, which focuses on the merit and importance of the proposed endeavour, prong two centres on the person. USCIS considers factors including the person's education, skills, knowledge and record of success in related or similar efforts; evidence of a detailed proposal or plan, developed by the person or with them in a significant role, for future activities related to the proposed endeavour; any progress already made toward achieving it; and interest from potential customers, users, investors or other relevant entities.

The list is not closed, and it is not a checklist

The guidance says including but not limited to, and officers decide each petition on a case-by-case basis. This is the prong where a petition is allowed to argue from its own facts, and where the strongest submissions go beyond the four named factors. The operative question is whether the specific person has the specific ability to carry the specific plan forward — which is why a petition that proves the plan separately from the person, or the person separately from the plan, tends to fail here even when both halves are strong.

Progress is the most under-used evidence

Progress toward the endeavour is on the list, and it is the cheapest thing to evidence and the most persuasive. A prototype, a pilot, a signed partnership, a publication that advanced the method, a dataset built, a grant awarded to the work itself — each is a fact showing the plan is under way rather than aspirational. USCIS gives the negative example directly: a petition that fails to establish the person is well positioned to advance an entrepreneurial endeavour to build a consulting business advising US banks nationally on customer relations. The failure there is not a weak CV. It is the absence of a plan, of steps taken, and of a link between the record and the proposed work.

The translation problem

Officers are told that strong petitions discuss how the person's record of success would translate into a proposed plan or forecast for continued success, the steps already taken toward those proposed activities, and how the plans tie into the person's background and expertise. Read that as a direct instruction: the burden is on the petition to make the link explicit. A Nobel-adjacent record in one discipline is worth nothing on prong two if the proposed endeavour sits in another and the petition never explains the bridge.

Entrepreneurs get a wider lane, not a lower bar

USCIS acknowledges that many entrepreneurs do not follow traditional career paths and that there is no single way an entrepreneurial venture entity must be structured. Officers may consider market size and share, job creation, revenue growth and other metrics — and also that other metrics may be of equal importance in establishing each of the three prongs. What that does not do is relax prong two. It means the evidence for it can look unlike an academic record, not that the evidence can be thin.

Prong three: on balance, the waiver benefits the United States

It is a balance, and it is stated as one

The third prong requires the petitioner to demonstrate that the factors in favour of granting the waiver outweigh those that support the requirement of a job offer and thus a labour certification, which is intended to ensure that the admission of foreign workers will not adversely affect the job opportunities, wages and working conditions of US workers. Officers assess whether the endeavour and the person being well positioned to advance it, taken together, provide benefits to the nation such that waiving the certification requirement outweighs the benefits that ordinarily flow from that requirement.

The three factors Dhanasar named

The guidance lists factors petitioners may submit evidence on, as outlined in Matter of Dhanasar. First, whether, in light of the nature of the person's qualifications or proposed endeavour, it would be impractical to obtain a labour certification. Second, the benefit to the United States from the prospective contributions, even if other US workers were also available. Third, whether the national interest in the contributions is sufficiently urgent to warrant forgoing the labour certification process, such as a time-sensitive public health or safety benefit. Officers may rely on one or more.

Why the third factor is the strongest lever in practice

The labour certification process is described in the guidance as primarily focused on a geographically limited labour market. That is the asymmetry the third prong exploits. A certification tests whether a qualified US worker exists in a defined area for a defined job. It cannot test whether a research programme reaches a milestone this year, whether a public health intervention arrives before an outbreak peaks, or whether a technology keeps pace with competitors abroad. Where the petition can show the value of the work is exactly the kind a labour market test does not measure, prong three has real content.

Self-employment and ownership

The guidance works through the entrepreneur case explicitly, because it is the one where the ordinary logic of the labour market test is weakest: where the person is self-employed in a manner that generally does not adversely affect US workers, or where the petitioner establishes or owns a business that provides jobs for US workers, there may be little benefit from the labour certification. That is a factor argument, not an automatic finding. It still has to be evidenced.

What prong three is not

It is not a place to repeat prongs one and two more loudly. The petition has to engage with the counterfactual — the labour certification the person would otherwise need — and explain why it would not capture the value on offer. A prong three section that never mentions the labour certification process has not argued prong three at all.

What has been settled since 2016

A preponderance standard, and a discretionary decision

Eligibility is shown by a preponderance of the evidence. The grant itself is discretionary, and the guidance directs that a decision denying a national interest waiver petition must include information about appeal rights and the opportunity to file a motion to reopen or reconsider. That is a procedural fact with substantive value: a denial on this route is often a document problem that can be addressed on a motion rather than a finding of ineligibility.

STEM has dedicated guidance, and it is favourable reading

The Policy Manual sets out guidance specific to persons with advanced degrees in science, technology, engineering or mathematics, alongside guidance on letters of support and other evidence from interested government agencies and quasi-governmental entities, and guidance specific to entrepreneurs. The STEM section carries its own content on how such endeavours can contribute to the United States achieving or maintaining technology leadership or peer status among allies and partners. In STEM cases, prong one is ordinarily the least contested.

Occupations still gate advanced-degree eligibility

The waiver sits inside EB-2, and the underlying classification has its own requirement: the intended occupation through which you plan to advance the endeavour must meet the definition of a profession — normally one for which a bachelor's degree or its foreign equivalent is the entry requirement. USCIS applies this case by case, including to some entrepreneurial endeavours. A person with a master's degree in engineering proposing an engineering endeavour fits. USCIS's own illustration of the boundary is a similarly educated person who intends to start a bakery. The degree does not carry the occupation.

No agency letter is required, and no intent to fail is required

Letters from interested government agencies and quasi-governmental entities are treated as a useful evidence type, not a condition. And on the outcome of the venture itself, the guidance is explicit: many innovations and entrepreneurial endeavours may ultimately fail despite an intelligent plan and competent execution, so petitioners are not required to establish that the proposed endeavour is more likely than not to succeed based solely on the usual metrics. What is required is a credible plan and a person positioned to execute it.

The consistent theme across ten years of guidance

Specificity. Every clarification since Dhanasar has pushed in the same direction: name the endeavour, describe the impact, show the plan, show the steps taken, and engage with the labour certification the waiver would replace. The prongs have not been tightened in substance. They have been made more concrete in application, which penalises petitions written at the level of a field and rewards petitions written at the level of a piece of work.

Worked example: the case the test is named after, and its pattern

Matter of Dhanasar itself concerned an engineer whose proposed endeavour was engaging in research and development relating to air and space propulsion systems. That single fact carries three of the clarifications in current guidance. The occupation was engineer. The endeavour was not. The distinction between the two is where the case gets taught from, and it is the reason prong one can be argued for a specialist inside a common occupation but not for a practitioner of the occupation as such.

Run a second illustration through the same structure. A data scientist at a hospital proposes to build and validate a prediction model for sepsis onset that is usable in community hospitals without specialist staff. Prong one: merit sits in health and in the advancement of a valuable technology; importance sits in the prospective impact across many hospitals and in the absence of a market mechanism that would deliver the tool — a national implication within a particular field, and a societal welfare argument, both available without a single revenue figure. Prong two: education, skills and record of success are the model, the validation work, the publication, the hospital deployment; plan and progress are the prototype, the pilot site, the dataset; third-party interest is the clinical collaborators and the community hospital network that agreed to run it. Prong three: impracticality is that the labour market test cannot identify a US worker for a plan that depends on a specific research programme already under way; benefit notwithstanding available workers is that a working early-warning tool has value whatever else is available; urgency is the preventable mortality a delayed deployment implies.

Now strip one element out of each prong and watch what happens. Remove the specifics of the endeavour — make it healthcare, artificial intelligence and medicine — and prong one has nothing to measure and prong two has nothing to position against. Remove the record of success and prong two becomes a plan with no author. Remove the plan and the pilot site and prong two has a record with no destination. Remove the labour certification from the discussion and prong three is an assertion that the work is valuable, which is prong one twice.

That is the pattern to take from the test. The three prongs are not three essays on the same theme. They are three different findings, evidenced by different things: the work and its prospective impact; you and your specific readiness; and a balance between a waiver and the labour market test the waiver replaces. A petition that can name, in one sentence each, what evidence goes to which prong, will usually also be a petition that survives step two.

Questions this raises

What are the three prongs of the national interest waiver?

Under Matter of Dhanasar, 26 I&N Dec. 884 (AAO 2016), the petitioner must show that the proposed endeavour has both substantial merit and national importance; that the person is well positioned to advance the endeavour; and that on balance it would benefit the United States to waive the job offer and the labour certification requirement. All three must be met.

What replaced the NYSDOT test?

Matter of Dhanasar withdrew the framework in Matter of New York State Dept. of Transportation, 22 I&N Dec. 215 (Acting Assoc. Comm'r 1998), and replaced it with the three prongs. The largest change was moving the enquiry from the area of employment to the proposed endeavour, and dropping the requirement that the benefit be national in geographic scope.

What is the difference between an occupation and an endeavour?

An endeavour is more specific than a general occupation. In Dhanasar the occupation was engineer and the endeavour was research and development relating to air and space propulsion systems. USCIS asks petitioners to describe not only what the occupation normally involves but what work the person specifically proposes to undertake.

Does my endeavour have to be national in geographic scope?

No. Officers are directed to focus on the nature of the proposed endeavour rather than only its geographic breadth. National importance can rest on national or global implications within a particular field, or on significant potential to broadly enhance societal welfare or cultural or artistic enrichment. Locally or regionally focused endeavours can qualify.

What counts as being well positioned to advance the endeavour?

USCIS weighs education, skills, knowledge and record of success in related or similar efforts; a detailed plan for future activities that you developed or helped develop; progress already made toward the endeavour; and interest from potential customers, users, investors or other relevant entities. The list is not exhaustive, and each petition is decided case by case.

Do I need a letter from a government agency for a national interest waiver?

No. Letters from interested government agencies and quasi-governmental entities are one useful evidence type that USCIS guidance addresses, and they can help explain urgency or benefits that exist even when other US workers are available. They are not a required element of any of the three prongs, and many petitions are granted without one.
