O-1 Advisory Opinion: What the Consultation Letter Is
By Kyle Farmer, Farmer Law PC, Austin, Texas.
Last reviewed: November 9, 2026.
Short answer: Most O-1 petitions need a written advisory opinion, called a consultation, from a peer group, labor organization or management organization in your field, or from a qualified person or persons in your area of ability. It is filed with the petition. The opinion is advisory: USCIS is not bound by it, and a negative opinion does not automatically mean a denial.

Why O-1 petitions need a consultation
Congress made consultation part of the O visa law (INA 214(c)(3), (c)(6)). The regulation says consultation with an appropriate U.S. peer group, labor organization or management organization about the nature of the work and your qualifications is mandatory before USCIS can approve an O-1 or O-2 petition (8 CFR 214.2(o)(5)(i)(A)). The USCIS Policy Manual calls it a statutorily mandated consultation process for all O petitions (USCIS Policy Manual Vol. 2, Part M, Ch. 7).
For the O-1 categories themselves, see our O-1A extraordinary ability and O-1B visa pages.
Who can write the advisory opinion
The source depends on the type of O-1:
| Petition type | Who provides the consultation |
|---|---|
| O-1A (sciences, education, business, athletics) and O-1B (arts) | A peer group in your area of ability, which may include a labor organization, or a qualified person or persons in your area of ability (8 CFR 214.2(o)(5)(ii)(A)) |
| O-1B (motion picture or television) | Both the union representing your occupational peers and a management organization in your area of ability (8 CFR 214.2(o)(5)(iii)) |
| O-2 (support personnel) | A labor organization with knowledge of the skill area; in motion picture or television, both a labor organization and a management organization (8 CFR 214.2(o)(5)(iv)) |
USCIS maintains a list of organizations that provide advisory opinions for O-1 and O-2 petitions (USCIS Policy Manual Vol. 2, Part M, Ch. 7).
What the opinion must say
- In writing and signed. The advisory opinion must be in writing and signed by an authorized official of the group or organization (8 CFR 214.2(o)(5)(i)(C)).
- Filed with the petition. The petitioner obtains the opinion and submits it with the petition (8 CFR 214.2(o)(5)(i)(C)).
- A favorable O-1 opinion should describe your ability and achievements in the field, describe the nature of the duties to be performed and state whether the position requires the services of a person of extraordinary ability (8 CFR 214.2(o)(5)(ii)(A)).
- A letter of no objection is also acceptable if the consulting organization has no objection to approval (8 CFR 214.2(o)(5)(ii)(A)).
- An unfavorable opinion must set out a specific statement of facts supporting its conclusion (8 CFR 214.2(o)(5)(i)(C)).
- Watermarks. If a consultation has a watermark or other distinctive marks, USCIS asks petitioners to submit the version that shows them, since copies without them may raise authenticity questions and cause delays (USCIS O-1 page).
Is the advisory opinion binding?
No. Consultations are advisory and are not binding on USCIS (8 CFR 214.2(o)(5)(i)(D)). The Policy Manual adds that a negative advisory opinion does not automatically result in denial, because the decision must be based on the totality of the evidence, and USCIS may consider evidence submitted to overcome a negative opinion (USCIS Policy Manual Vol. 2, Part M, Ch. 7).
A consultation is also not a substitute for the O-1 evidence itself. The petition still has to meet the extraordinary ability or achievement standard with its own documentation.
When no consultation is needed
- No appropriate group exists. If the petitioner shows that an appropriate peer group, including a labor organization, does not exist, USCIS decides the petition on the evidence of record (8 CFR 214.2(o)(5)(i)(G); USCIS O-1 page).
- Arts readmission within 2 years. For extraordinary ability in the arts, USCIS waives consultation when you seek readmission to perform similar services within 2 years of a previous consultation. The petitioner should submit a copy of the prior consultation and ask for the waiver (8 CFR 214.2(o)(5)(ii)(B); USCIS O-1 page).
Practical tips
- Match the consultation to the field. Choose a group or person whose field matches the work in the petition, so the opinion can speak to your achievements and the duties.
- Plan the timing. The opinion has to be ready when the petition is filed, and the petition can be filed no more than 1 year before the work starts. USCIS suggests filing at least 45 days before employment begins (USCIS O-1 page).
- Keep it consistent. The opinion’s description of your work and the job should match the petition, the contract or summary of terms and any itinerary.

Who writes the advisory opinion for an O-1A?
A peer group in your area of ability, which may include a labor organization, or a qualified person or persons in your area of ability. It must be in writing and signed.
Is an O-1 advisory opinion binding on USCIS?
No. Consultations are advisory and not binding. A negative opinion does not automatically lead to denial, because USCIS decides on the totality of the evidence.
