LegalOS
The AI-powered immigration law firm for complex work visas
LegalOS is an AI-powered immigration law firm for complex U.S. work visas.
Our AI agents generate a USCIS-ready petition package in 24–48 hours, including forms, support letters, and a structured evidence memo.
Every case is reviewed and signed by licensed immigration attorneys with 40+ years of experience and a near-100% approval rate, so companies get both speed and reliability. LegalOS already supports O-1, H-1B, L-1A, L-1B, TN, EB-1A, EB-1C, and EB-2 NIW petitions and has a 100% approval rate so far across all visa categories.
