EB-2 NIW: Recommendation Letter vs. Expert Opinion Letter—what’s the difference?
Both can support your petition, but they bring different perspectives.
📝 A recommendation letter comes from someone who knows you or your work—often a supervisor, colleague, collaborator, or client who has worked with you. It describes your contributions and the impact they observed through specific examples.
🔍 An expert opinion letter provides an independent assessment by a qualified subject-matter expert who does not need to have worked with you personally. The expert reviews your supporting records, explains the significance of your work, and connects the analysis to the NIW framework.
For both, what matters is:
✅ Relevant expertise and a clear basis of knowledge
✅ Specific contributions and outcomes
✅ Disclosure of relationships
✅ Supporting evidence consistent with the claims
Letters help explain and corroborate your record. Neither establishes NIW eligibility on its own or guarantees approval.
International Evaluations connects petitioners and immigration attorneys with relevant specialists from our network of 350+ professors and industry experts.
