Thanks. I understand your opinion:
(1) The unique source for the request of employment letter is the instruction of I-485 Form. Based on this source, the copy of the passport, the I-140 notice, medical examination, and etc. must be sent; but for EB1A, the employment letter is not must.
(2) Surely, sending employment letter will strengthen the petition.
We are talking in different paths: “whether must send” and “it can strengthen petition”.
Anyhow thank you, to strength the petition, I will send as you said.
By the way, how do you know I have no Olympic Gold Medals? I have a dozen, which are made of Chocolate.
Thanks again.
