請教大家：我的485 receipt notice上有這麽一段話。

剛收到485的recipt notice，上麵有這麽一段話：

As a reminder, you may request to change employers under INA 204(j) if your
Form I-485 Adjustment application has been pending for at least 180 days and
your underlying Form I-140 is approved or is still pending. In order to do
so, you should supplement the Form I-485 record of proceeding with
documentation relating to the new job offer that forms the basis of the INA
204(j) protability request.

我的類別是Eb1A，為什麽也有這麽一段話？請問最近遞485的Eb1A們，你們的receipt notice上有這麽一段話嗎？

我究竟可不可以在180天內換工作啊？我現在的工作很快要沒了，必須找新工作，等不及485批了。

謝謝大家！
