Employers transferring specialized knowledge employees to the United States through the L-1B visa are facing significantly higher denial rates in 2026. USCIS is applying stricter scrutiny to what constitutes "specialized knowledge" — and many petitions that would have been approved in prior years are now being denied or returned with RFEs.
What USCIS Is Challenging
Adjudicators are questioning whether the knowledge claimed is truly "specialized" or merely job-specific training that any qualified worker could acquire. Officers are also looking more closely at whether the U.S. position genuinely requires the transferred employee's specific knowledge, or whether the role could be filled domestically.
Impact on Multinational Employers
Companies relying on L-1B transfers for global talent mobility are seeing disruptions. The increased scrutiny also affects L-1 to green card pathways, since delays at the L-1B stage push back the entire immigration timeline. Combined with expanded employer site visits and higher premium processing costs, L-1 program costs are rising substantially.
