H-1B expert opinion letters, also known as specialty occupation letters or expert opinion letters, are documents written by an independent expert to support an H-1B visa application.
These letters are crucial for demonstrating that the offered position qualifies as a specialty occupation, which requires specialized knowledge and a bachelor’s degree or higher. The letter explains why the position necessitates expertise in a particular field and why the beneficiary’s qualifications are relevant.
The primary purpose of a specialty occupation letter is to determine whether a particular position qualifies as a specialty occupation for an H-1B petition. Such letters provide a detailed explanation of the educational background necessary to perform a position’s specialized duties.
Experts in the field analyze the nature of the company and its industry, the position in the context of the company, and the background required for the position as determined by the industry.
Taking into consideration the job duties required of the candidate, a specialty occupation letter clearly demonstrates that the proffered position is a specialty occupation requiring expertise in a particular field. Depending on the specific requirements of a case, specialty occupation letters can also be crafted to explain why a candidate’s particular background is relevant to the position at hand.


Key Purposes of H-1B Expert Opinion Letters:
- Specialty Occupation Determination:
The primary function is to prove that the position meets the criteria for a specialty occupation, requiring a bachelor’s degree or higher in a specific field.
- Demonstrate Relevance of Qualifications:
The letter explains how the beneficiary’s education, experience, and skills align with the job requirements.
- Support H-1B Eligibility:
By providing a professional evaluation, the letter strengthens the H-1B petition and increases the likelihood of approval, according to evaluation companies.
- Address Request for Evidence (RFE):
Expert opinion letters can be submitted in response to an RFE from USCIS, clarifying any doubts about the specialty occupation or the beneficiary’s qualifications.

What is Specialty Occupation for an H-1B?
The term “Specialty Occupation” is central to the H-1B visa and refers to a position that requires:
- Theoretical and practical application of a body of highly specialized knowledge.
- Attainment of a bachelor’s or higher degree in a specific specialty (or its equivalent) as a minimum for entry into the occupation in the United States.
For an H-1B EOL (Expert Opinion Letter), the concept of “Specialty Occupation” is crucial because the letter aims to demonstrate to the U.S. Citizenship and Immigration Services (USCIS) that:
- The job being offered qualifies as a Specialty Occupation. This means the position’s duties are so complex and specialized that a bachelor’s degree or higher in a specific field is the standard minimum requirement for someone to perform the job. The expert opinion can analyse the job duties, industry standards, and typical educational requirements for similar roles to support this claim.
- The beneficiary (the foreign worker) has the necessary qualifications (i.e., the required degree or its equivalent through a combination of education and work experience) to perform the duties of that specialty occupation. The expert can evaluate the beneficiary’s credentials and explain how they meet or exceed the educational and experiential requirements of the position.

4. What happens after 6 years of H-1B?
After six years on an H-1B visa, the visa holder must either return to their home country for at least one year or seek an alternative visa status to remain in the U.S. One common path for staying in the U.S. is to pursue a Green Card through employment, often initiated by filing an I-140 petition (Immigrant Petition for Alien Worker).
