A single source degree is a single academic credential, one degree from one institution, that on its own establishes the educational equivalency required for an employment-based immigrant visa petition. For I-140 petitions, particularly EB-2 advanced degree cases, USCIS applies this standard in a way that differs significantly from how educational credentials are evaluated for H-1B nonimmigrant petitions.
Understanding this distinction before filing can prevent documentation approaches that work for H-1B but are insufficient for I-140.
What the Single Source Degree Standard Means for I-140
For H-1B specialty occupation petitions, USCIS allows a combination of education and qualifying work experience to establish the equivalent of a U.S. bachelor’s degree. Three years of progressive, specialized work experience can substitute for one year of college under the three-for-one rule. This combination approach is well established in H-1B adjudication.
For I-140 employment-based immigrant visa petitions, particularly those filed under the EB-2 advanced degree category, USCIS has applied a stricter standard. A single credential, or a series of credentials from a single educational progression, must establish the required equivalency. Combining a degree with work experience to manufacture an equivalency that the academic record alone does not support is not accepted in the same way as it is for H-1B.
This is the single source degree standard: the degree itself must do the work.
Why This Matters in U.S. Immigration
The practical consequence of this standard is significant for Indian professionals and other foreign nationals with three-year bachelor’s degrees who are pursuing employment-based green cards.
The H-1B to I-140 Transition Problem
Many Indian professionals receive H-1B approval with a three-year bachelor’s degree supplemented by a combination of postgraduate coursework and qualifying work experience. When the same individual moves forward with an I-140 EB-2 petition, they sometimes assume the same documentation approach will work.
It will not, at least not in the same form.
For EB-2 advanced degree cases, USCIS expects the advanced degree to be established by the academic record alone. A three-year bachelor’s degree plus a two-year master’s degree represents a complete academic progression that clearly establishes the advanced degree equivalent. The combined 10+2+3+2 structure used in the Indian educational system results in 17 total years of formal education, clearly exceeding the U.S. master’s degree standard.
By contrast, a three-year bachelor’s degree alone, supplemented by work experience to reach bachelor’s equivalency, does not position the applicant well for EB-2 advanced degree purposes.
What USCIS Has Said About This
The American Immigration Lawyers Association has addressed this issue in its engagement with USCIS. USCIS has indicated that for EB-2 and EB-3 cases, it does not equate a three-year diploma plus a post-baccalaureate diploma as the equivalent of a U.S. bachelor’s degree, and does not accept a combination of academic background and work experience as the equivalent of a U.S. bachelor’s degree for green card purposes.
This is a meaningful distinction from H-1B, where the three-for-one rule is explicitly available.
Common Misconceptions About Single Source Degrees
Misconception 1: If It Worked for H-1B, It Will Work for I-140
The most common misconception is that educational documentation approved for an H-1B petition can simply be carried forward into an I-140 without reanalysis. H-1B and I-140 petitions are evaluated under different standards, and the credential evaluation prepared for H-1B may not be framed to address the I-140 standard.
Misconception 2: A Three-Year Degree Cannot Qualify for I-140
This is also incorrect. A three-year bachelor’s degree combined with a master’s degree, where the master’s is a genuine academic credential, not a short diploma program, can establish the advanced degree equivalent for EB-2. The credential evaluation must address the combination clearly.
Misconception 3: Any Two Credentials Can Be Combined
Not all combinations work. A three-year bachelor’s degree plus a one-year postgraduate diploma is not the same as a three-year bachelor’s plus a two-year master’s degree. USCIS evaluates the substance of the academic record, not just the number of credentials listed.
How USCIS Evaluates Single Source Degree Questions
USCIS adjudicators reviewing I-140 petitions involving foreign credentials reference AACRAO EDGE guidance for country-specific information on educational systems. For Indian credentials, officers are aware of the 10+2+3 versus 10+2+4 distinction and the implications for U.S. degree equivalency.
The credential evaluation submitted with the I-140 petition must:
Address the specific degree or degrees held and their structure within the country’s educational system. Confirm the U.S. equivalency level clearly. For EB-2, establish master’s equivalent for EB-2, bachelor’s equivalent for EB-3. Explain the analytical basis for the equivalency conclusion rather than simply asserting it. Address the single source nature of the equivalency, distinguishing it from a combination of education and work experience.
An evaluation that does not address the single source standard directly leaves the officer without the analytical framework needed to approve the petition on this basis.
When Professional Credential Guidance Is Appropriate
The single source degree question is one area where the framing of the credential evaluation can make a material difference in the outcome of the I-140 petition. Professional credential guidance is most valuable when:
The beneficiary holds a three-year Indian bachelor’s degree and is pursuing EB-2 classification. The beneficiary’s master’s degree is from a program of unusual structure or short duration that may raise questions about its equivalency. The beneficiary previously received H-1B approval through a combination approach and needs the I-140 evaluation to be reframed. A prior I-140 petition received an RFE related to educational qualifications.
“I treat every client as if they are my only client.” That is the commitment Sheila Danzig, EdD, brings to every credential evaluation prepared at Career Consulting International. Trained under Professor Mathew B. Michael Clark, ScD of the American Evaluation Institute (AEI), with USCIS-accepted evaluations since 2002, she co-authored research on the acceptance of the three-year Indian bachelor’s degree published in the Indian Journal of Education. Each I-140 case receives individual attention.

How This Connects to Credential Evaluation and RFE Support
The single source degree standard makes the credential evaluation the most important document in an I-140 petition involving foreign credentials. An evaluation that does not engage with this standard explicitly gives the adjudicating officer no analytical basis for resolving the question in the petitioner’s favor.
For petitions that have already received an RFE related to educational qualifications, the response must include an evaluation that directly addresses whatever the officer found insufficient. For single source degree RFEs, this typically means an evaluation that explains why the academic record on its own establishes the required equivalency, and an expert opinion letter that supports this conclusion with independent analysis.
Practical Tips
Read the I-140 RFE or denial notice carefully if one has been issued. Identify specifically whether the question raised was about the single source degree standard, the degree level, or the field of study.
Do not assume that documentation effective for H-1B will serve the I-140 without review. The analytical framing is different, and a credential evaluation prepared only for H-1B purposes may not address what the I-140 officer needs to see.
If the credential includes a combination of degrees, confirm that the master’s degree is a genuine two-year academic credential, not a one-year postgraduate diploma, before relying on the combination for EB-2.
Coordinate the credential evaluation with the immigration attorney before the petition is finalized. The evaluation and the attorney’s brief should address the single source degree question using consistent analysis.
Frequently Asked Questions
What is a single source degree for I-140 purposes? A single source degree is one credential, or a standard academic progression of credentials, that on its own establishes the required degree equivalency for an I-140 petition. For EB-2 advanced degree cases, USCIS expects the academic record alone to establish the advanced degree equivalent, without combining education and work experience in the same way permitted for H-1B specialty occupation petitions.
Can a three-year Indian degree qualify for an I-140 EB-2 petition? Yes, when combined with a two-year master’s degree. A three-year bachelor’s plus a two-year master’s under the Indian 10+2+3+2 system results in 17 years of formal education, clearly establishing advanced degree equivalency. The credential evaluation must address this combination as an academic progression rather than a degree-plus-experience combination.
Why does the single source degree standard apply to I-140 but not H-1B? H-1B specialty occupation petitions explicitly allow the three-for-one work experience rule, permitting three years of qualifying experience to substitute for one year of college. I-140 employment-based green card petitions operate under different regulatory standards. USCIS has indicated it does not accept a combination of academic background and work experience as a bachelor’s degree equivalent for green card purposes.
What happens if my I-140 petition receives an RFE about the single source degree? The RFE response must include a credential evaluation that directly addresses the single source degree standard. The evaluation should explain why the academic record on its own, or as a genuine academic progression, establishes the required equivalency. An expert opinion letter coordinated with the evaluation can strengthen the response further.
Does a one-year postgraduate diploma count as a master’s degree for I-140? Not necessarily. A one-year postgraduate diploma is structurally different from a two-year master’s degree and may not be recognized as the master’s equivalent for EB-2 purposes. The credential evaluation must address the specific program and its U.S. equivalency. One-year diplomas are evaluated on their specific content and structure rather than their title.
Can the same credential evaluation work for both H-1B and I-140? An evaluation prepared for H-1B purposes may not address the I-140 single source degree standard. For professionals who need evaluations for both purposes, discussing both requirements before ordering allows for documentation prepared to serve each category’s specific needs. A single evaluation can address both if framed appropriately.
What does USCIS look for in a credential evaluation for EB-2 advanced degree cases? USCIS expects the evaluation to confirm the foreign degree is equivalent to a U.S. master’s degree or higher, explain the analytical methodology, address the specific structure of the foreign educational system, and establish that the equivalency rests on the academic record rather than a combination with work experience. Officers reference AACRAO EDGE guidance for country-specific educational system information.
