Why Applicants Trust Expert Opinion Letters to Overcome RFEs

Prevent RFEs with Expert Opinion Letters

Last updated on November 20, 2025

When USCIS issues a Request for Evidence (RFE), it is usually not questioning your potential.
Instead, it is assessing whether your qualifications, education, and experience have been presented in a clear, USCIS-compliant manner.

This is where Expert Opinion Letters play a critical role, by converting raw credentials into structured, USCIS-ready evidence.

For individuals applying for U.S. work visas or permanent residency, receiving an RFE can be stressful and confusing. An RFE often means additional documentation, tighter deadlines, and uncertainty about how USCIS is interpreting your case. Without proper context, even strong profiles can face delays or denials.

The good news is that many RFEs are preventable.
A well-prepared Expert Opinion Letter, drafted by qualified academic or industry experts, helps clarify degree equivalency, specialty occupation requirements, and professional qualifications — significantly strengthening your petition and reducing the risk of future RFEs.

What is causing the rise in USCIS RFEs?

If USCIS is tossing RFEs your way, it might not be because your credentials are incomplete. So, why is this happening?

AI Application Reviews: USCIS now relies on automated tools like Artificial Intelligence (A.I.) to screen cases. Specifically, some missing details or insufficient details might trigger an instant RFE.

Immigration Vetting: Paperwork investigation and background checks are now very strict, especially in H-1B and EB-2 NIW cases.

Translation Mix-ups: Many applicants think that just a translated document is enough to get through. But USCIS usually needs an official evaluation along with the translation.

Confusing Evidence: If USCIS officers fail to connect your degree, work experience, and qualifications to U.S. standards, they are most likely to issue an RFE.

In short, USCIS is saying: We are not 100% about your case, and we need more proof.

The Most Common H-1B RFE Reasons Include:

      • AC21 and the six-year limit

      • Degree in a separate or not closely related field of study

      • Determination of a specialty occupation

      • F-1 OPT or CPT

      • In-house projects at consulting companies

      • Job itinerary issues

      • LCA issues

      • Licensing requirements

      • Living far away from your place of work

      • Petitions filed on behalf of businesses for professionals not typically associated with that field.

      • Questionable employer-employee relationship

      • Requests for an extension or change of status

    What Exactly is an Expert Opinion Letter?

    An Expert Opinion Letter (EOL) is a formal, USCIS-recognized document authored by a qualified industry expert or academic professional. It explains how an applicant’s education, work experience, and achievements meet U.S. immigration standards and regulatory requirements.

    In many RFE cases, the issue is not missing credentials but unclear presentation of evidence. Expert Opinion Letters address this gap by translating raw documents into structured, USCIS-ready explanations.

    In simple terms, an Expert Opinion Letter allows a recognized specialist to professionally validate your qualifications, degree equivalency, and career impact in a way USCIS officers can clearly assess.

    Applicants usually need them when:

        1. H-1B Visa – Proves that your job is a “specialty occupation” requiring a specific skill.
        2. EB1A Visa – Shows that you have exceptional talents with strong support from experts.
        3. EB2 NIW – Shows your skills and job benefits to the U.S. nationally.
        4. O-1 Visa – Confirms you have extraordinary talents in arts, science, or business.
        5. L-1 Visa – Verifies your executive or managerial experience for transferring within a company
        6. PERM Labor Certification – Helps prove there are no qualified U.S. workers available for the job.

      Every single category has individual demands; therefore, just simple recommendation letters won’t work for you.

        Frequently Asked Questions (FAQs)

        Does an Expert Opinion Letter increase the approval rate of my RFE response?

        Yes. Expert Letters often improve approval rates because USCIS relies on third-party academic or industry experts. A strong letter clarifies the petitioner’s position and reduces the risk of denial.

        Why do Expert Opinion Letters help in overcoming USCIS RFEs?

        Expert Opinion Letters directly answer USCIS doubts about your job role, specialty occupation, education, or experience. They provide independent professional validation, which increases the chances of getting an RFE approved.

        When should I get an Expert Opinion Letter for my visa application?

        You should get it when filing your petition or immediately after receiving an RFE for specialty occupation, skills mismatch, education equivalency, experience, or progressive experience.

        Who writes Expert Opinion Letters for RFE cases?

        USCIS requires these letters to be written by qualified university professors, industry experts, or PhD-level evaluators who have recognized authority in the field.

        How fast can I get an Expert Opinion Letter for an RFE?

        Most agencies deliver Expert Letters within 24–48 hours, which helps applicants meet tight USCIS deadlines for RFE responses.

        Are Expert Opinion Letters required for every H-1B or EB-2 RFE?

        No, but they are highly recommended for any case where USCIS questions your job’s specialty occupation, education, or experience proof.

        Do Expert Opinion Letters work for difficult or complex RFE cases?

        Yes. They are especially helpful for complex RFEs because experts provide detailed academic and industry justification that the petitioner alone cannot provide.

            1. Presents your achievements in USCIS-Friendly Language: Applicants usually need them when USCIS officers may not be familiar with your specific field. Additionally, an Expert Opinion Letter explains your work in easy-to-understand language.
            2. Authority: USCIS gives your applications more weight when your skills and educational qualifications are confirmed by a senior industry leader.
            3. Covers Weak Spot: Expert Opinion Letters explain gaps in resume, unusual degrees, or international credentials clearly.
            4. Prevents Uncertainty: A well-written Expert Opinion Letter explains exactly why your foreign degree is valuable to the U.S.
