Receiving an RFE (Request for Evidence) from USCIS can be stressful for employers, attorneys, and foreign workers. Even the strongest petitions can face delays or denials if key documentation is missing or unclear. Understanding the most common mistakes USCIS makes — and how expert opinion letters can quickly address them — is essential for a smooth immigration process.
What Is an Expert Opinion Letter?
An expert opinion letter is a professional evaluation written by a recognized authority in a specific academic or professional field. In immigration cases, these letters help:
Confirm foreign education or experience aligns with U.S. standards.
Validate specialized knowledge or skills required for a specific job.
Provide independent, credible evidence USCIS can rely on.
Expert letters are commonly used in H-1B petitions, PERM labor certifications, I-140 filings, and RFE responses.
Top 5 USCIS RFE Mistakes
1. Misunderstanding Education Equivalency
The Mistake: USCIS often questions whether a foreign degree matches U.S. standards, especially for STEM or specialized fields.
How Expert Letters Help: A qualified professor or industry expert analyzes the coursework and confirms equivalency, translating international education into U.S.-recognized terms.
Real Example: A foreign hire had a Mathematics degree, while the H-1B job required Computer Science. An expert letter clarified that the degree covered the necessary technical coursework, and USCIS approved the petition.
2. Questioning Specialized Fields of Study
The Mistake: Officers sometimes doubt whether a candidate’s major qualifies them for a specific role, especially in niche industries.
How Expert Letters Help: An expert explains how the applicant’s education or work experience aligns with the position and industry standards.
Real Example: A cybersecurity specialist faced an RFE questioning degree relevance. A cybersecurity industry expert detailed typical hiring practices and degree applicability, resulting in USCIS approval.
3. Insufficient Documentation of Work Experience
The Mistake: Many petitions lack clear evidence when professional experience is used to substitute for a degree or to show advanced expertise.
How Expert Letters Help: An expert validates years of professional experience, showing equivalence to missing academic qualifications.
Real Example: A worker missing the final year of a bachelor’s degree had 12 years of industry experience. An expert letter equated this experience to the missing academic requirement, moving the green card process forward.
4. Confusing or Unique Job Roles
The Mistake: USCIS may struggle to understand highly specialized or emerging roles, such as AI engineers, data scientists, or blockchain developers.
How Expert Letters Help: Experts explain job functions, industry practices, and required qualifications, bridging the knowledge gap for officers.
Real Example: An AI startup faced an RFE for a machine learning engineer. An expert letter clarified role responsibilities and the necessity of specific qualifications, leading to petition approval.
5. Misinterpreting Foreign Credentials or Licenses
The Mistake: USCIS sometimes undervalues foreign certifications, licensures, or professional designations.
How Expert Letters Help: Experts provide authoritative validation, explaining equivalency to U.S. certifications or professional standards.
Real Example: A medical technologist with a foreign license faced an RFE questioning credentials. An expert letter confirmed the license’s U.S. equivalency, and USCIS approved the application.
