The L-1 nonimmigrant classification enables a U.S. employer under certain circumstances to transfer an executive or employee to its office in the United States. It also allows a foreign company which does not yet have a U.S. office to send an executive or employee to the United State for the purpose of establishing one. The L-1 visa has two subcategories: L-1A for executives and managers, and L-1B for workers with specialized knowledge. Spouses and children under 21 years of age of L-1 visa holder are allowed to accompany the visa holder and will receive the L-2 non-immigrant classification. Spouses may work, without restriction, in the US, but to do so they will need to apply for work authorization and pay the applicable filing fee.
