Which signed documents do I need to submit?

The O-1 visa is for individuals with extraordinary ability in fields such as sciences, arts, education, business, or athletics, and a significant portion of the supporting documentation must be properly signed to establish the authenticity of the information presented. Several signed documents are typically central to the petition:

• Contracts or offer letters: executed by the contracting party (sponsor or employer) and the beneficiary, describing the terms and the activities to be performed in the United States.
• Recommendation letters: signed by experts or institutions in your field, attesting to your extraordinary ability.
• Consultation letter: a written opinion signed by a relevant peer group, labor organization, or management organization in your field, when required.
• Itinerary of engagements: the schedule of events and activities in the United States, which may require the signature of the sponsor or the professional themselves.

Requirements vary depending on the specifics of each case, so always review the most current guidance on the official USCIS website and consult with qualified professionals. Keeping documents well-organized and properly signed strengthens the credibility of the information and the overall integrity of the petition.
