The L-1B nonimmigrant classification enables a U.S. employer to transfer a professional employee with specialized knowledge relating to the organization’s interests from one of its affiliated foreign offices to one of its offices in the United States. This classification also enables a foreign company which does not yet have an affiliated U.S. office to send a specialized knowledge employee to the United States to help establish one. Your employer must file Form I-129, Petition for a Nonimmigrant Worker, with fee, on your behalf.
To qualify, you must:
Generally have been working for a qualifying organization abroad for one continuous year within the three years immediately before your admission to the United States; and
Be seeking to enter the United States to provide services in a specialized knowledge capacity to a branch of the same employer or one of its qualifying organizations.
Specialized knowledge either means knowledge you have about the petitioning organization’s product, service, research, equipment, techniques, management, or other interests and its application in international markets, or an advanced level of knowledge or expertise in the organization’s processes and procedures. (See 8 CFR 214.2(l)(1)(ii)(D).) Your employer must also meet general qualifications
