The L-1B Visa is a non-immigrant visa that allows companies to transfer employees with specialized knowledge from a foreign office to a U.S. office. This visa is specifically designed for employees who possess unique skills or expertise that are essential to the company's operations. To qualify for the L-1B Visa, the employee must have worked for the company for at least one continuous year within the last three years. The visa is typically granted for a period of up to three years, with the possibility of extensions, allowing companies to bring in talent that contributes to their success in the United States.
