Hi, I am so sorry that your o1 got denied with such credentials, I am in a similar situation, hardship pending with dos close to 15 month, applied for o1 visa went to Vermont under premium processing , got RFE, 2/3 criteria satisfied - major significance not met, planning to file response , my query is do they provide officer ID number. I have the fax notice it does not show any such information. the reason I am asking, i have a friend whose eb1 was approved after a response to rfe in her case , officer ID number was present in the rfe notice, he got some prior experiences from google search which was helpful fro the RFE notice response, my lawyers not giving a clear answer. thank you
