Four Agent ConfigurationsHowever your work is structured. Aventus has the agent role that fits.
Aventus offers four distinct petitioner configurations to match how O-1 talent actually works in 2026 — solo consulting, founding ventures, foreign payroll, or single-employer relationships. Each carries the same multi-employer flexibility under USCIS rules.
Multiple Employer Agent
Work with unlimited U.S. clients under one petition. The most common configuration for consultants, freelancers, and senior specialists who serve several companies simultaneously.
Self-Employment Agent
Launch and run your own U.S. venture while on O-1. Aventus signs as your authorized petitioner so you can operate as the founder or principal of your own company.
Foreign Employer Agent
Stay employed by your foreign employer while doing U.S.-based work. Aventus represents the petitioner relationship that USCIS requires for foreign-payroll arrangements.
Single Employer Agent
For talent in long-term engagements with one U.S. employer, but who want agent-based representation rather than direct sponsorship — preserving future flexibility.
How It WorksFrom profile to petitioner-signed filing — in one connected flow.
The handoff between O1DMatch and Aventus is built around the structural reality of agent-based O-1: separate functions, working alongside each other, with your attorney completing the legal triangle.
