O-1 Visa US Agent Services

O-1 US agent consultant meeting with a visa client

Your U.S. agent for an O-1 petition

Bring your U.S. work plans together with a clear point of coordination. Moose Advisors offers US Agent services for O-1 nonimmigrant visa petitions, serving as the U.S. agent petitioner where the proposed arrangement and required authorizations support that role. We work with you, your employers and your immigration attorney to organize the engagements and supporting business information behind your petition.

Our service helps reduce the administrative burden of coordinating parties, tracking documents and presenting a consistent work itinerary, so you can focus on your professional commitments.

O-1A and O-1B: support for extraordinary talent

The O-1 classification covers individuals with extraordinary ability or achievement. O-1A applies to extraordinary ability in sciences, education, business or athletics. O-1B covers extraordinary ability in the arts or extraordinary achievement in the motion picture or television industry.

Moose Advisors provides U.S. agent coordination for professionals and entrepreneurs pursuing qualifying work arrangements. Your immigration attorney evaluates the applicable standard and supporting evidence. An O-1 beneficiary cannot self-petition; a properly structured agent-filed petition may be appropriate for qualifying circumstances.

Coordinate multiple employers and engagements

A U.S. agent may petition in arrangements involving traditionally self-employed workers or workers who use agents to arrange short-term employment with multiple employers. For an appropriate multi-employer petition, Moose Advisors can act as the authorized agent and help coordinate the parties and documented engagements in one organized process.

We help gather employer details, work dates, locations and agreed terms for your attorney to review. This supports a consistent presentation of the proposed work; it does not provide unrestricted permission to work for any employer or on any project.

Signing an employment contract for an O-1 petition

Employment contracts, agent authorization and itinerary

A clear petition starts with clear work arrangements. Moose Advisors helps coordinate employment contracts or documented oral agreements, employer authorizations and the event or activity itinerary supporting your Form I-129 petition. We help identify missing information and reconcile names, dates and locations across the materials supplied by you and your employers.

When an agent represents a beneficiary and multiple employers, USCIS calls for contracts and a complete itinerary identifying the engagements, actual employers and work locations. Requirements differ when an agent functions as the employer or represents a foreign employer. Your attorney determines the evidence needed for your particular arrangement.

Foreign employers and founder-led businesses

A foreign employer may file an O petition through an authorized U.S. agent. This can include a foreign company owned wholly or partly by the beneficiary, provided the arrangement meets the applicable requirements and involves actual qualifying work rather than speculative employment.

Moose Advisors works with you and your immigration attorney to review the proposed agent role, required authorizations and documentation of U.S. engagements. For a foreign-employer arrangement, that review includes the agent’s authority to file the petition and accept service of process on the employer’s behalf in the proceedings described by USCIS.

Freelance creative professional planning U.S. projects with an O-1 visa agent

Who needs a U.S. agent for an O-1 visa?

The O-1 visa cannot be self-petitioned. A U.S. employer, a U.S. agent, or a foreign employer acting through a U.S. agent must file Form I-129 for you. Many people search for an “O-1 visa sponsor”; when no single U.S. employer can sponsor you, an O-1 agent petitioner is often the most practical route.

  • Freelancers, consultants and independent artists with several U.S. clients, venues or studios
  • Founders and executives employed by a foreign company with no U.S. office
  • Musicians, performers and athletes planning a tour, season or series of events
  • Researchers, creators and filmmakers with project-based U.S. engagements

Common questions about O-1 U.S. agents

Answers to common questions about O-1 visa agents, agent petitions and multiple-employer itineraries. Still unsure which route fits you? Request a free consultation.

No. An O-1 petition must be filed by a U.S. employer, a U.S. agent, or a foreign employer through a U.S. agent. An agent petitioner is a common solution for freelancers, consultants, founders and artists.


The agent files Form I-129 as the petitioner, coordinates the employers and engagements in your itinerary, holds the required authorizations and serves as the contact for USCIS correspondence. Your immigration attorney handles legal strategy and evidence.


Yes, when the arrangement qualifies. USCIS expects contracts or written terms with each employer and an itinerary showing the dates, locations and type of work for every engagement.


Yes. A foreign employer may authorize a U.S. agent to file the O petition and accept service of process in the United States on its behalf.


Processing times vary. USCIS offers premium processing for Form I-129 for an additional fee, with action within 15 business days. Preparing contracts and the itinerary early helps you file sooner.
