An SOC Code Appropriateness Expert Opinion is designed to support H-1B petitions where USCIS questions whether the offered position has been classified under the appropriate Standard Occupational Classification (SOC) code. An independent subject-matter expert carefully reviews the duties of the offered position and compares them with the occupational tasks delineated in authoritative resources such as the Occupational Outlook Handbook (OOH) or O*NET. The opinion provides a detailed analysis of how the position’s actual duties align with the selected SOC classification and explains why the assigned SOC code appropriately represents the nature and scope of the offered position.
