Why this firm ranks
Scores combine delivery signals, evidence quality, freshness, project fit, location verification, and risk penalties. Local results only use verified U.S. offices from official firm websites. Non-U.S. results are rotated from public country pools capped at five firms per eligible country, excluding OFAC-blocked countries and countries with fewer than three qualified firms in the dataset.
