L-1B Specialized Knowledge Visa
Transferring your company's technical core — proprietary, advanced knowledge uncommon in the industry.
Overview
The L-1B is for intracompany transferees with specialized knowledge of the company's products, services, systems, or techniques. USCIS scrutiny is high — the knowledge must be advanced and atypical within the industry, not just expertise at one's job. Maximum stay is five years.
We build knowledge matrices, training-investment evidence, and industry-norm comparisons that survive RFEs.
Who May Qualify
- One year of qualifying foreign employment in the prior three years
- A qualifying corporate relationship
- Specialized knowledge that is advanced, proprietary, or uncommon
- Continued employer control if placed at client sites
How We Help
- Specialized knowledge documentation and RFE-proof support letters
- Client-site placement compliance under the employer-control rules
- L-1B to L-1A upgrade strategy and green card sequencing
Frequently Asked Questions
Can L-1B employees work at client sites?
Only if they remain under the principal control of the petitioning employer — we document this carefully.
How is specialized knowledge proven?
Through proprietary systems documentation, training records, and evidence that the knowledge is not commonly held or easily transferable.
