I'm unclear on the "Statement of Objective" for my Non-Immigrant, Multi-Entry B to be requested in Los Angeles.

Who has obtained a "Statement of Objective" before? I am not sure if the host company in Thailand or the foreign company sending me should provide it? Or both?

Since it is sandwiched between points 1 and 3, which are about the host company, I assume it's the Thai host company. But still want to hear from someone with experience.

Lastly, what it should contain and how brief can it be? On a company letterhead can it simply say "Objective of stay: Mr. Aaron Aaron España will be consulting about the product quality and coordinating production during his stay in Thailand, as we receive orders from our American trade partners, XYZ Co, USA."?
