I Reply the RFE for the Question of L-1B Visa with Specialized Knowledge

Hi William:

I am in L-1B visa three years already. After my employer sent out the L-1B visa renew application last month, we got an notice of Request For Evidence (RFE), asking for evidence of my "specialized knowledge". How to I reply the RFE for the question of L-1B visa with specialized knowledge?


To prove a specialized knowledge capacity for the RFE response, the foreign national's knowledge must be different from or surpass the ordinary or usual knowledge of an employee in the particular field, and must have been gained through significant prior experience with the petitioning organization. 

A specialized knowledge employee must have an advanced level of expertise in his or her organization's processes and procedures or special knowledge of the organization which is not readily available in the United States labor market. Some characteristics of an employee who has specialized knowledge are that he or she: 

  • Possesses knowledge that is valuable to the employer's competitiveness in the market place; 
  • Is uniquely qualified to contribute to the U.S. employer's knowledge of foreign operating conditions;
  • Has been utilized as a key employee abroad and has been given significant assignments which have enhanced the employer's productivity, competitiveness, image, or financial position; and
