What Is a US Agent Petitioner?
The missing piece between you and your American opportunity
When applying for an O-1 or P-1 visa, you need two things: an immigration attorney for legal expertise and a US petitioner to sponsor your application. That’s where we come in.
A US Agent Petitioner:
Signs and files your Form I-129 as the official sponsor
Takes legal responsibility for your employment compliance
Enables you to work with multiple clients or employers
Handles ongoing USCIS obligations during your stay
Without a Traditional Employer? We are Your Solution. Many exceptional professionals don’t fit the single-employer model. Freelancers, consultants, entrepreneurs, and artists need flexibility. As your US agent, we provide the official sponsorship required by USCIS while giving you freedom to work how you want.
Important Note: We are not a law firm. We work alongside your chosen immigration attorney who handles all legal aspects of your case.
