O-1 Advisory Opinion Letter: Who Writes It

The O-1 advisory opinion (consultation letter) is mandatory. Who can write it, what it must say, and what to do if the group declines.

Page reviewed October 8, 2026.

Is an O-1 advisory opinion required?

Yes.

Under 8 CFR 214.2(o), an O-1 petition needs a written advisory opinion, called the consultation, from an appropriate U.S. peer group, a labor or management organization, or for the O-1A and the O-1B in the arts a person with expertise in the field. The consultation is mandatory before the petition can be approved. A favorable opinion should describe your ability and achievements, the duties you will perform, and whether the position requires someone of extraordinary ability. The opinion is advisory and does not bind USCIS, and an unfavorable one is not an automatic denial.

What does the advisory opinion rule require?

The consultation is mandatory before an O-1 or O-2 petition can be approved. It is one of the items every petition must include, together with the contract, the explanation of the events and the evidence of eligibility.
The opinion must be in writing, come from a group with expertise in the specific field, and be signed by an authorized official.
A peer group is a group or organization made up of practitioners of your occupation. A collective bargaining representative may be the appropriate peer group.
Consultations are advisory and not binding on USCIS. An unfavorable opinion must set out a specific statement of facts supporting its conclusion, and USCIS may still approve the petition after considering the evidence that answers it.
Motion picture and television petitions need an opinion from both a labor organization and a management organization.

Who can write the O-1 advisory opinion for each classification?

Classification	Who the opinion comes from
O-1A	An appropriate U.S. peer group, a labor or management organization, or a person or persons with expertise in the field
O-1B in the arts	An appropriate U.S. peer group, a labor organization, or a person or persons with expertise in the field
O-1B motion picture and television	Both a labor organization and a management organization

What should a favorable opinion say?

For the O-1A and the O-1B in the arts, a favorable opinion should cover three points. The organization may instead send a letter of no objection.

Your ability and achievements in the field.
The nature of the duties you will perform.
Whether the position requires the services of someone with extraordinary ability.

How does the process usually run?

Find the right organization. USCIS keeps a list of organizations that provide consultation letters, grouped into labor organizations, management organizations and peer groups. It is not exhaustive, and the rules allow other sources, including a person or persons with expertise in the field.
Send the organization a short request. The rules do not prescribe a package. The organization needs enough to comment on the work and your qualifications, which usually means a description of the job and event, your CV, the criteria evidence, and the contract and itinerary.
Check the letter. It should be signed by an authorized official and cover the three points above. If it carries a watermark or other distinctive mark, file that version, because a copy can raise doubts about authenticity.
File it with the petition. USCIS recommends filing at least 45 days before the start of employment and no more than one year before.

What if the group declines or does not answer?

If the opinion comes from a group that is not a labor organization, USCIS forwards a copy of the petition to the appropriate national labor organization. The regulation sets mandatory response times for that organization. If it does not, USCIS decides on the record without the opinion. These are regulatory time limits, not processing times.
If no appropriate peer group exists, the petitioner must establish that, and USCIS then decides on the evidence of record. The burden is on the petitioner, so keep a record of who you contacted, when and what they said.
You can file without the actual opinion by following the form instructions: send the organization a copy of the petition, name it on the petition and tell it that USCIS will contact it. USCIS warns that such a petition takes substantially longer to process.
In the arts, the consultation is waived if you seek readmission to perform similar services within two years of a previous consultation. File the earlier consultation with a waiver request.

Which mistakes cause delays?

Treating the consultation as optional.
Using an organization without expertise in your specific field.
A letter that skips the three required points, or a negative letter with no stated facts.
Filing an unmarked copy when the original carries a watermark.
Claiming that no peer group exists without proof. The petitioner carries the burden of establishing that no appropriate group exists.
Treating a favorable opinion as proof of eligibility. It is advisory, and USCIS weighs all the evidence together.

Common questions

Do I need an advisory opinion for an O-1 visa?

Yes. The regulation calls consultation with an appropriate peer group, labor or management organization mandatory before an O-1 petition can be approved. The written opinion is submitted with the petition.

Who can write an O-1 advisory opinion?

A U.S. peer group, a labor or management organization, or for the O-1A and the O-1B in the arts a person or persons with expertise in the field. The source needs expertise in the specific field, and an authorized official must sign.

What should the opinion say?

A favorable opinion should describe your ability and achievements, the duties you will perform, and whether the position requires someone of extraordinary ability. The organization may send a letter of no objection instead.

What if no union or peer group exists in my field?

The petitioner has to establish that no appropriate group exists, and USCIS then decides on the evidence of record. Keep a record of who you contacted and the result. A person with expertise in the field can also give the opinion.

Can I file if the union does not respond?

You can file without the opinion, but the form instructions say to send the organization a copy of the petition and name it on the petition. USCIS warns that it takes substantially longer to process a petition filed without the actual opinion.

Does Lando guarantee approval?

No. USCIS decides every petition, and Lando does not promise an outcome. Lando is not a law firm. Petitions are prepared in coordination with licensed U.S. immigration attorneys.
