We maintain high standards because USCIS gives weight to expert credentials. Here's what we look for.
You must hold a terminal degree in your field. This is non-negotiable — USCIS evaluates expert credentials closely, and a doctoral qualification is the foundation of credibility.
Current or recent affiliation with a U.S. university, research institution, hospital, or established organization. Professors, associate/assistant professors, research scientists, and senior industry professionals are all welcome.
A record of peer-reviewed publications, patents, industry recognition, or equivalent credentials that establish you as an authority in your discipline. USCIS needs to see why your opinion carries weight.
You must have no prior professional, personal, or financial relationship with the petitioner whose case you assess. USCIS places the highest evidentiary weight on independent expert opinions.
Expert opinion letters must be clear, precise, and persuasive. You should be comfortable writing detailed analytical documents in academic or professional English.
While we welcome applications from all disciplines, we have particular demand in the following areas.
Submit your application with your credentials. We review every submission within 48 hours. If your qualifications meet our standards, we add you to our expert network and match you with cases in your field.
