L-1 visas enable international companies to transfer key managers and professionals from a foreign subsidiary to the U.S. parent company (or from a foreign parent company to a U.S. subsidiary).  Often those employees are also eligible for permanent residence status ("green card") without the necessity of a labor certification.  Unlike other working categories, spouses of L-1 employees can obtain work authorization. 

Our firm has extensive experience representing multinational companies in L-1 cases.   Often the L-1 visa can be obtained in just a few weeks, especially if the employer has a pre-approved blanket L-1 petition.
