The interpretation of "specialized knowledge" for the L-1B classification has evolved substantially over the years since the L-1 visa category was created in 1970. The term has been analyzed in decisions by the Board of Immigration Appeals (BIA), elaborated on in agency guidance, addressed by regulations, and modified by legislation. Most recently, however, there has been increased scrutiny of the L-1 program that has led to rigid application of the specialized knowledge standard that runs contrary to the purpose for which the program was created.
