I-485與申請EAD/AP的疑問 - 移民

I-485的費用內含I-765/I-131, 但一定要同時遞交三份表格嗎?

板上資訊 "現在規定I485 I765 AP全都綁在一起 不能分開"...
指的是"費用"綁在一起, 不是"遞交時間"要一起, 這樣理解對不對呢?
(因為看到I-485 instruction: If you file i-485, no additional fee
is required to also file an addition for EAD on i-765 and/or AP
on i-131. You may file these forms concurrently. If you choose to
file i-765 and/or i-131 separately after.... you must also submit
a copy of your i-797c as evidence of the filing of i-485.)

想確認一下, 遞交I-485後, 才申請EAD/AP的話, 不用再多付費了, 對嗎?
謝謝!
