Better Expert Opinion Letters

built upon a bedrock of research

What is an Expert Opinion Letter (EOL) and how can an EOL from ProfVal add value?​

An Expert Opinion Letter from ProfVal represents a highly customized evaluation from a distinguished expert regarding whether a position or an individual's credentials meet USCIS visa requirements. 

Expert Opinion Letters from ProfVal are regularly used in initial applications, in response to a Request for Evidence (RFE), or in response to a denial.

"Employers report the time lost due to the increase in denials and Requests for Evidence [RFE] has cost millions of dollars in project delays and contract penalties, while aiding competitors that operate exclusively outside the United States" (Forbes)

Letters from the talented experts we work with have successfully supported visa applications of entrepreneurs, individuals, small companies, fortune 500 corporations, start-ups, and nonprofits for a variety of visa types.

Executives at Work

An Expert Opinion Letter for an L-1A, L-1B, O, or visa requires a detailed analysis that varies based on your background and visa requirements.


A Work Experience Expert Opinion Letter examines how your work experience corresponds to the academic requirements of a U.S. academic degree.

An Expert Opinion Letter from ProfVal can supplement your visa petition at various stages, including an initial application, an RFE, or denial appeal.  To understand the value of your Expert Opinion Letter, try, for a moment, to step into the shoes of a USCIS agent.


Her academic and professional background is unlike yours. And for that reason, she may be unfamiliar with your business or your area(s) of expertise and may question both. Her questions can result in an RFE; she's seeking evidence that will indicate whether a position, you, or a beneficiary meets the qualifications of a particular visa. An Expert Opinion Letter from ProfVal can help to provide her with evidence and a detailed and highly customized document that increases transparency related to your position or background. In professional, yet relatable terms, an Expert Opinion Letter from ProfVal will help her understand how your position relates to the knowledge, abilities, and specialized background required of your visa.
