L-1B Intracompany Transferee with Specialized Knowledge
Intracompany transfer for employees with specialized knowledge — narrower than L-1A and often the harder of the two L visas to win.
You have specialized knowledge of your company's product, service, research, equipment, techniques, management, or other interests — and your company needs that knowledge in a US office.
