An advisory opinion is often a required part of the O-1 filing package. It usually comes from a labor organization, peer group, or management organization that can comment on the nature of the work and the beneficiary's qualifications in the field.
The exact requirement depends on the case type. Motion picture and television cases may involve both a labor and management consultation. Other fields may rely on a relevant union, guild, peer group, or similar industry body. If no appropriate group exists, the petition may need to explain why a consultation should be waived.
Good advisory-opinion preparation usually means identifying the right organization early, assembling the right supporting documents, and presenting the case in a way that matches the standards of the consulting body. Delays often happen when the wrong organization is approached or the request package is incomplete.
Waiver analysis can also matter. In some situations, the petitioner may be able to show that there is no suitable peer group or that a prior consultation can support readmission for similar services. That argument has to be documented clearly.
This service fits naturally with petitioner and agent strategy, RFE response support, and the main O-1 visa overview. Advisory-opinion problems can slow an otherwise strong petition, so they should be handled early.
If you are not sure which consultation applies to your field, begin with the free evaluation. That is usually the best starting point for mapping the filing structure before deadlines become tight.
