What Is a US Agent Petitioner?
When applying for an O-1 or P-1 visa, USCIS requires a US entity to file your petition. This is where we come in.
A US Agent Petitioner:
Sign and file Form I-129 as your official sponsor
Enable you to work with multiple US employers or clients
Maintain your employment compliance throughout your stay
Handle ongoing USCIS obligations and amendments
The Alternative to Traditional Sponsorship
Unlike single-employer sponsorship, our agent model provides the flexibility that modern professionals need. Whether you're consulting for multiple companies, building your own venture, or working for a foreign employer, we structure your petition for maximum opportunity.
