Companies operating in the US can apply to the relevant USCIS service center for an L1 visa to transfer someone to the US from their overseas operations. Employees in this category will, initially, be granted an L-1 visa for up to three years.
There are two types of employees who may be sponsored for USA L1 visas:
The legal definition of management and executive roles for these purposes is quite strict, and a detailed description of the duties attached to the position will be required. In particular, the executive or manager should have supervisory responsibility for professional staff and/or for a key function, department or subdivision of the employer. Such personnel are issued an L1A visa, initially for a three year period extendible in two year increments to a maximum of seven years.
Specialized Knowledge Staff
This category covers those with knowledge of the company's products/services, research, systems, proprietary techniques, management, or procedures. Staff in this category are issued an L1B visa, initially for three years extendibles to a maximum of five years.
On completing the maximum allowable period in L-1 status, the employee must be employed outside the United States for a minimum of one year before a new application is made for L or H status.
