Overview
The L-1B visa is for employees with specialized knowledge of the company's products, services, research, equipment, techniques, or management, allowing transfer from an overseas affiliate to the U.S. "Specialized knowledge" means knowledge not readily available in the U.S. labor market. L-1B has a maximum validity of 5 years and is not subject to an annual cap.

Frequently Asked Questions
What is "Specialized Knowledge"?
USCIS defines specialized knowledge as: (1) special knowledge of the company's products and their application in international markets; or (2) advanced knowledge of the company's processes and procedures. The key is proving the knowledge is proprietary, not publicly available, and not easily transferable to a new hire.
L-1B vs H-1B?
L-1B: no cap, no lottery, no wage requirement, requires intracompany transfer with 1 year foreign experience. H-1B: annual cap (65,000+20,000), lottery, prevailing wage required, no intracompany requirement. L-1B suits multinational transfers; H-1B suits direct U.S. employment.
Can L-1B be converted to L-1A?
Is L-1B denial rate high?
L-1B RFE rates have increased in recent years due to stricter USCIS scrutiny of "specialized knowledge." Common RFE issues: insufficient explanation of why the knowledge is truly "specialized," failure to explain why a U.S. worker couldn't be trained. Detailed initial documentation of knowledge uniqueness is strongly recommended.
