We work with credentialed professors, researchers, and industry professionals to prepare expert opinion letters for U.S. immigration petitions. If you have deep expertise in your field and meet our independence standards, we would like to hear from you.
USCIS places significant weight on expert opinion letters from individuals who are genuinely independent from the petitioner — no prior professional relationship, no co-authorship, no employment connection. Our network is built on verified credentials, genuine independence, and field-specific expertise.
We match each petitioner to an expert whose background directly aligns with the visa category being argued — an adjudicator reviewing your letter needs to see that your credentials are relevant to the specific discipline and criteria.
Associate Professor or above at an accredited university, or equivalent senior research position at a recognized institution
Senior position (10+ years experience) at an established company, with verifiable expertise in your specific field of practice
Publications, citations, patents, professional certifications, awards, or other documented evidence of recognized expertise
No prior professional, employment, or co-authorship relationship with the petitioner you are evaluating — required by USCIS
