Strengthen your National Interest Waiver petition with USCIS-compliant expert opinion letters from our network of 170+ independent specialists across STEM, healthcare, business, and social sciences.
Tell us about your case — we respond within 24 hours.
An EB2-NIW Expert Opinion Letter is a formal, research-backed document written by an independent authority in your field. Unlike a personal recommendation, it provides an objective, evidence-based analysis of your qualifications and proposed endeavor — structured specifically to meet the criteria USCIS requires for National Interest Waiver approval.
USCIS adjudicators review hundreds of petitions across every industry. They may not have specialized knowledge in your field. An expert opinion letter bridges that gap — translating your complex achievements into clear, compelling evidence that directly addresses the legal standards governing your case.
Every letter we produce is custom-written to fit your unique background, proposed endeavor, and legal strategy. No templates. No generic language.
Our letters don't just check a box — they provide the independent, objective validation that USCIS adjudicators are trained to look for.
Published professors, researchers, and industry specialists across every major field. Each expert is independently credentialed and qualified to opine on your specific area.
Every letter addresses all three prongs of the Matter of Dhanasar framework with objective, verifiable evidence in the precise format USCIS recognizes.
Each letter is researched and written from scratch based on your unique qualifications, proposed endeavor, and your attorney's strategic guidance.
Standard delivery in 7–10 business days. Rush delivery available in 3–5 business days for urgent deadlines.
We work directly with your immigration attorney to align the letter with their legal strategy. Attorneys tell us which prongs to emphasize.
Every letter includes free revisions. We want you and your attorney to be completely confident in the final document.
Every EB2-NIW petition is adjudicated under the three-prong test established by Matter of Dhanasar.
