L-1B — Intracompany Transferee — Specialized Knowledge

The L-1B is a US nonimmigrant visa for multinational employees with specialized knowledge of their employer's products, services, research, equipment, or techniques. The knowledge must be distinct or special — beyond general industry expertise. The employer files Form I-129; no formal education requirement applies.

Initial stay is up to 3 years (1 year for new US offices), renewable in 2-year increments to a 5-year maximum. L-2 spouses are work-authorized incident to status — no separate EAD needed. Dual intent is permitted, so L-1B holders can pursue a green card while maintaining status.

This visa is ideal for technical specialists, engineers, or researchers employed abroad by a multinational who need to transfer unique company-specific expertise to a US office.
