The L-1A visa has duration up to SEVEN years for managers and executives and L-1B up to five years for persons of SPECIALIZED knowledge. The duration of stay is issued for an initial period of three years and may be extended for additional periods. The immigration rules permit an L-1 specialized knowledge employee to EXTEND stay to the seven-year limit if the specialized knowledge employee had actually been performing executive or managerial duties for the preceding six months prior to the extension REQUEST, and the USCIS had been notified of the change of duties through the FILING of an amended petition. In the case of a new office, the visa is issued for one year and extensions are possible. Extensions can be granted in two-year increments: executives and managers can obtain two such extensions, and specialized knowledge personnel one such extension.
