USCIS routinely wants a statement in the letter that the company is intending to employ you in the future. Why?
Because the I-140
petition is for an offer of employment prospectively AFTER you have your resident status. The resident status is based on employment with your sponsor after you receive your status. You do not have to be working for the sponsor until after adjustment.
It doesn't matter if you have worked for 100 years on a temp visa for the sponsor, what counts is the intent to employ after adjustment and you need to follow through on that intent for at least 6 months after adjustment.
So unfortunately in most cases USCIS does want the prospective offer of employment from the sponsoring employer.
It is too bad the the company lawyers take advantage of the company policy by charging extraordinary fees. It is not unusual for a company to require using their chosen counsel because it is so much easier on HR to deal with one firm that has all their info and knows everything about the company.
But the I-485 is not really in any involving the company except for the letter.
The only way you can really look at this as an investment in a future of freedom.
