O-1A and O-1B petitions carry some of the widest fee spreads in immigration — from ~$6,000 at published-price boutiques to $15,000+ at large full-service firms.
The O-1 category requires evidence of sustained national or international acclaim, so drafting is heavy: expert letters, exhibit indexing, and a detailed petition brief. O-1 also needs a U.S. employer or agent as the petitioner. Compare the firms below, or book a free strategy call and we help you shortlist by your field, timeline and budget.
