No employer sponsorship. No PERM labor certification. But to secure an EB-2 National Interest Waiver, you must prove all three Dhanasar prongs — and the hardest one to prove is that your proposed work genuinely matters to the United States. Aligned with current USCIS adjudication standards including the January 2025 policy update, our field-matched expert letters address each prong with the specificity USCIS now requires. Draft review included before anything is delivered.
An EB-2 NIW expert opinion letter is a formal written statement from an independent credentialed expert — providing an evidence-based assessment of the petitioner's proposed endeavor and qualifications under the three-prong framework established in Matter of Dhanasar (2016). It is submitted as supporting evidence in EB-2 National Interest Waiver self-petitions filed with USCIS on Form I-140.
To qualify for a National Interest Waiver, a petitioner must demonstrate three things: (1) the proposed endeavor has substantial merit and national importance; (2) the petitioner is well-positioned to advance the endeavor; and (3) on balance, it would benefit the United States to waive the job offer and labor certification requirements. All three prongs must be addressed — and the January 2025 USCIS policy update makes clear that adjudicators now expect specificity and direct relevance. Generic endorsements and letters that could apply to any professional in the field carry significantly less weight than they once did.
An effective EB-2 NIW expert letter is built around the petitioner's specific proposed endeavor — not their general credentials. The national importance of that endeavor, the petitioner's demonstrated track record in advancing it, and the U.S. benefit of waiving the normal labor market requirements all need to be argued with evidence. That is what a well-prepared expert letter does. Every letter we prepare is matched to a vetted independent expert in the petitioner's field — you choose from a shortlist, you review the draft, your approval is required before anything is issued.
Every letter is structured around your specific proposed endeavor — some addressing all three Dhanasar prongs comprehensively, others focused on the specific prong the petition most needs to establish.
EB-2 NIW petitions typically include three to five expert opinion letters. Each letter may address different aspects of the Dhanasar framework — some covering all three prongs comprehensively, others focused on the specific prong the petition most needs to establish.
The most common use case. A petitioner filing an initial NIW needs expert letters that address all three Dhanasar prongs — substantial merit, national importance, and the petitioner's positioning — from independent credentialed experts in their field.
The January 2025 USCIS guidance clarified a meaningful pathway for entrepreneurs whose work creates jobs, drives innovation, or addresses significant U.S. needs. Expert letters can document the national importance of the endeavor and the petitioner's unique positioning to advance it. For petitions that benefit from a structured business plan, see our Immigration Business Plan service.
The updated 2025 USCIS guidance explicitly deemphasises the prior focus on STEM fields. Educators, public health professionals, policy researchers, artists, and others can qualify if the proposed endeavor's national importance is properly documented. Expert letters from the right independent voice make this argument.
The most common NIW RFE trigger. When USCIS questions whether the proposed endeavor rises to national importance — rather than just personal or organisational benefit — a targeted expert letter addressing Prong 1 with specific evidence is included in the response. Rush available in 48 hours.
When USCIS accepts the national importance of the endeavor but questions whether this specific petitioner is well-positioned to advance it, a qualifications-focused letter from a field expert who can assess the petitioner's track record is the standard response component.
For petitioners from countries with significant EB-2 priority date backlogs, getting the petition right the first time — without triggering an RFE — is critical to protecting the earliest possible priority date. Strong expert letters from the outset reduce that risk.

"The letter addressed all three Dhanasar prongs with specific evidence from my case — not a generic endorsement. My attorney said it was one of the strongest NIW letters she had reviewed."
