A U.S. agent can be used when your work is freelance, consultative, or project-based rather than tied to a single employer. In this setup, the agent files the O-1A petition on your behalf and represents you in the United States.The underlying contracts must clearly reflect the nature of your work and be appropriate for your background and level of expertise. USCIS uses this structure to confirm that your work in the U.S. is legitimate and pre-arranged.For example, a public figure or consultant may work with multiple companies rather than one employer. In this case, a registered U.S. agent can represent you and consolidate multiple engagements into a single petition, demonstrating to USCIS that you have ongoing, valid work in the U.S.
