What is an O1 Expert Opinion/Advisory Letter?
An O-1 expert opinion letter (also sometimes called a consultation letter or advisory opinion) is a critical piece of evidence in an O-1 non-immigrant visa application. The O-1 visa is for individuals with extraordinary ability in the sciences, arts, education, business, or athletics, or those with a demonstrated record of extraordinary achievement in the motion picture or television industry.
This letter is written by an authority or expert in the applicant’s field who can attest to the applicant’s extraordinary ability and achievements. It serves to:
- Validate the Applicant’s Achievements: The expert provides an objective evaluation of the applicant’s accomplishments, explaining their significance and impact within the field.
- Establish Credibility: The letter from a recognized expert adds weight and credibility to the applicant’s claims of extraordinary ability.
- Provide Context for USCIS: U.S. Citizenship and Immigration Services (USCIS) officers may not be experts in the applicant’s specific field. The opinion letter helps them understand the applicant’s achievements in the context of their industry and why they rise to the level of “extraordinary ability.”
- Support Specific O-1 Criteria: The letter should ideally address specific criteria that the applicant is using to demonstrate their extraordinary ability (e.g., awards, publications, critical roles, commercial success).


Key Components of a Strong O-1 Expert Opinion/Advisory Letter:
- Expert’s credentials: Establish the expert’s authority and qualifications.
- Detailed evaluation: Provide a thorough assessment of the individual’s achievements and contributions.
- Specific examples: Offer concrete examples of the individual’s work and its impact.
- Comparison to peers: Compare the individual to others in their field, highlighting their exceptional abilities.
- Clear conclusion: Clearly state that the individual meets the O-1 visa requirements.
