回複：關於485的新難題又來了。請8大師或其他高手解憂。謝了。

Company ability to pay is required for I-140 to be approved.  Your actual pay with company B is irrelevant unless you have been paid PW since your priority date.  Hey, you don't even need to work for B before I-485 approval. Yet, B needs to prove their ability to pay PW.
