Case Strategy for Early Scholars in the EB-1B Outstanding Researcher Green Card Category
August 26, 2026Understanding the Three-Year Experience Requirement for EB-1B Outstanding Researchers and Professors
The EB-1B classification for outstanding researchers and professors can be challenging to navigate because USCIS adjudicators may interpret certain requirements differently depending on the evidence presented. Although this degree of subjectivity can make an EB-1B petition seem daunting, it can also create an opportunity: a well-structured petition can guide the adjudicator toward a favorable understanding of the evidence.
This is particularly relevant when an otherwise strong EB-1B candidate does not have three years of traditional, post-graduate professional experience. With the right evidence and legal strategy, experience obtained during an advanced degree program may, in some circumstances, contribute toward meeting the regulatory requirement.
For early-career academics and researchers, understanding how USCIS evaluates this experience, and how it should be documented, can be an important part of determining whether an EB-1B petition is viable.
Can Experience During an Advanced Degree Program Count Toward the EB-1B Requirement?
Ordinarily, an EB-1B petitioner must demonstrate at least three years of experience in teaching and/or research in the academic field. Importantly, however, the regulations allow certain teaching or research experience obtained while pursuing an advanced degree to qualify.
Under 8 CFR 204.5(i)(3)(iii), experience acquired while pursuing an advanced degree may be considered if the individual obtained the degree and, in the case of teaching, had full responsibility for the courses taught. For research experience, the research conducted toward the degree must have received recognition within the relevant academic field as outstanding.
This distinction can be especially valuable for Ph.D. candidates and other early-career researchers who have accumulated substantial academic experience but have not yet spent three years working after receiving their degree.
Teaching Experience
Teaching performed as part of a graduate program may potentially qualify when the individual had primary responsibility for the course. Evidence showing responsibility for course instruction, grading, examinations, and student evaluations can therefore be important.
The course does not necessarily have to correspond to the foreign national’s precise research specialty. Instead, the course should generally relate to the academic field in which the individual is claiming expertise. For example, depending on the circumstances, a researcher specializing in a particular area of computer science may be able to rely on broader computer science teaching experience.
The same general concept may apply in fields such as pharmaceutical science, supply chain management, engineering, or other academic disciplines where an individual’s teaching responsibilities encompass a broader field than their specific research niche.
Research Experience
Research experience obtained while pursuing an advanced degree can present a more complicated analysis because the regulations require the research to have been recognized as outstanding.
There is no simple formula for determining whether research meets this standard. Instead, the petition should present the available evidence demonstrating how the research was viewed within the relevant academic community.
Potential evidence may include:
- Publications in scholarly journals
- Citations to the foreign national’s work
- Presentations at academic conferences or other professional venues
- Recognition from universities or research institutions
- Awards or other distinctions
- Media coverage
- Research grants or funding
- Evidence that the research influenced subsequent work or was used to obtain additional funding
- Other objective evidence demonstrating recognition within the field
An award received as a student may not independently establish eligibility under the EB-1B criterion concerning major prizes or awards. Nevertheless, it can still be useful evidence when establishing that research performed during an academic program received recognition from others in the field.
Likewise, research that resulted in grant funding, or research findings that contributed to securing subsequent funding, may provide meaningful evidence of the significance and recognition of the work.
Documentation Can Make or Break the Experience Analysis
Identifying potentially qualifying experience is only the beginning. The petition must also establish that experience through persuasive documentation.
The EB-1B regulations require evidence of teaching and/or research experience in the form of letters from current or former employers. Those letters should identify the writer and provide a specific description of the foreign national’s duties. See 8 CFR 204.5(i)(3)(iii).
For teaching experience, supporting evidence could include a course syllabus, teaching appointment, employment agreement, or other university records, together with a detailed letter from an appropriate university official. The documentation should establish both the nature of the teaching responsibilities and the period during which the teaching occurred.
When properly documented, qualifying teaching performed during a Ph.D. program may potentially be combined with qualifying teaching performed after the degree was awarded. The experience also does not necessarily need to have occurred continuously or at a single institution. Where experience was accumulated at multiple universities, however, each period should be carefully documented.
Research experience calls for a similarly deliberate approach. A letter from a department chair, principal investigator, or other person who directly supervised the research can help establish the nature and duration of the work.
Additional letters may be particularly valuable when they explain why the research should be regarded as outstanding. For example, when a foreign national is one of several authors on a publication and is not the first author, a letter from the lead author explaining the individual’s specific contributions and the importance of those contributions can provide useful context.
Research does not necessarily have to result in a publication to be relevant. If the work was presented at a conference or another professional forum, independent experts may be able to explain the significance of the research and why it received recognition within the field.
That recognition can serve a dual purpose. It may help establish that research performed during an advanced degree satisfies the experience requirement while also supporting the broader case that the foreign national qualifies as an outstanding researcher or professor.
Building the Evidence Around the Strength of the Case
The amount and type of supporting evidence needed will depend heavily on the overall record.
A petition supported by extensive objective evidence, such as publications, citations, research utilization, funding, institutional recognition, and other indicators of professional impact, may require less reliance on testimonial evidence to establish the significance of the research.
Conversely, an early-career researcher with limited publications, citations, and professional experience may need more extensive expert testimony to explain why the research should nevertheless be viewed as outstanding.
This distinction matters because letters of recommendation and other testimonial evidence generally carry less persuasive weight than objective documentation when evaluated by an adjudicator. As a result, a petition that relies heavily on expert opinions should be supported, wherever possible, by independent evidence that corroborates those opinions.
The strongest strategy is therefore not simply to accumulate documents, but to determine what each piece of evidence establishes and how the evidence collectively satisfies the regulatory requirements.
