Two options present within the L-1 nonimmigrant visa category:
L-1A Intracompany Transferee Executive or Manager
This allows executives or managers abroad to come work in a US office location, or in some situations to set establish a US location.
L-1B Intracompany Transferee
In this case, specialized knowledge allows an employer to transfer a processional employee with specialized knowledge relating to the organization’s interests.
Requirements for an L-1 visa include demonstrating a qualifying relationship and proving sufficient physical space or setting up a new space. The employee must be working in an executive or managerial capacity for at least one full year within the last three years. USCIS requires significant evidence for this visa type and has a high rate of requesting further information.
