How important are expert opinion letters in an EB-1 visa petition? Has anyone received an RFE because their letters were too generic?
Expert opinion letters can make a huge difference in EB-1 cases, especially for proving extraordinary ability or outstanding contributions. USCIS usually looks for detailed, evidence-based analysis instead of generic recommendation language.
A strong letter should explain:
• Why the applicant’s work is significant in the field
• How their achievements compare to others professionally
• Independent recognition and impact of their contributions
• Specific evidence supporting awards, publications, judging roles, or leadership
Many RFEs happen when letters are too broad or only praise the applicant without connecting achievements to USCIS criteria. Independent experts with strong credentials usually carry more weight than close colleagues or supervisors.
