The L-1 Visa is a non-immigrant visa that allows companies to transfer employees from an overseas office to a U.S. office. It is primarily designed for managers, executives, and employees with specialized knowledge. This visa helps multinational companies maintain a global workforce and facilitate business operations in the United States. There are two main types of L-1 Visas: L-1A for managers and executives, and L-1B for employees with specialized knowledge. To qualify, the employee must have worked for the company for at least one continuous year within the last three years. The L-1 Visa is valid for up to three years, with possible extensions.
